Implementing custom color management

Hello
I need to develop a PS plugin that implements its own color management. In particular, I need to be able to bypass Photoshop's display colour management to do soft-proof of my own, i.e. I need to control the display RGB values directly.
Does Photoshop SDK allow for such a control?
Thanks in advance
b

I guess the image display callbacks are what I need... I need to be able to replace PS live softproofing (i.e. what happens when user chooses "Proof Colors") by my own one, for any colour mode: RGB, CMYK, Multichannel.
Is there any known workaround for that?
Cheers

  • Color Management Custom Profiles - None available (Vista)

    I get bad color in my prints from LR. My printer supports Adobe RGB, and hence I believe it would fix the problem is I could get LR to convert the image to Adobe RGB before printing. Under Color Management, I click on "Managed by Printer" to get a popup menu that has both "Managed by Printer" (checked) and "Other" as options. I select "Other" and a window appears with the title "Choose Profiles" and the text "Choose profiles to appear in Custom Profile popup:" The problem is that the window is empty. There are no choices! I have checked and I have the ICC files installed in Windows\System32\spool\drivers\color and they are associated with my printer by windows. I copied and add icm versions of the icc files. Still no profiles appear.
    Does this work for others? Can anyone get any options to show up?
    Thanks for any help or advice.

    AdobeRGB and sRGB are NOT printer profiles, they are color spaces and you should not be able to select them in Lightroom. You need actual printer profiles if you want to print application managed from lightroom. Almost every reasonably modern printer includes them. It looks like this printer does not include them in a way so that you can use them. On most printers, you can still print printer managed, but it appears that this printer is not correctly color managed. I checked out the manual for it and it clearly is not color managed at all. Typical for HP's consumer line unfortunately. Apart from having a profile generated by any of the places that do that for you (which is about as expensive as an ink cartridge), I don't think you can print to this thing from Lightroom at all. In this case, really the printer manufacturer is to blame. They should have been doing ICC/ICM color management ages ago instead of relying on all applications to be dumb. It still stinks though.

  • Color management - Spyder2 PRO or Custom ICC profile?

    I've got a Canon MP800 (multi-function inkjet) that I use at home for prints. As I get more serious about photography, I'm noticing that the colors I get on my prints are not matching what I see on my monitor very well.
    I'm using an Apple LCD, and I've done the software calibration and created a custom monitor profile. From within Aperture, I then use the canned Canon print profile for the type of paper I'm using. In the print dialog box, I select "no color management". Still, the prints tend to have a slight orange cast or they are "warmer" than I see them on my monitor.
    I am considering two possible next steps, and I'd like to get your feedback on which would be most appropriate for my set-up.
    1. Get the Spyder2 PRO Studio hardware/software combo, or
    2. Get a custom ICC profile made for my printer through Neil Barstow/Pixl
    They cost about the same, but I'm wondering what would give me the best prints. I'm still a novice when it comes to color management, but I'm reading Martin Evening's "PS CS2 for Photographers" and learning a lot.
    Your help is appreciated!

    I thought I'd mention that I have the EyeOne Display 2, and it came with a certificate that takes $200 off the csot of the more advanced system if I decide to upgrade at some point...
    So the earlier note about profiling the monitor first is a good one, and you might be out as much money if you do need to also profile the printer.
    I'll add a note that everyone really needs to profile monitors, especailly if you have two or you aren't really comapring apples to apples when doing image comparisons across both screens.
    Confusingly the EyeOne instructions claim if you have two monitors running on one video card it can only profile one of the monitors. That's not true on the Mac, you just need to move the menu bar to the screen you wish to profile. OS X has an icc profile per screen that gets set by the software.

  • Can't get Lightroom Color Management to select custom profiles

    I can't get Lightroom Color Management to select custom profiles.
    - I select "other" in Profile,
    - a pop-up box shows me numerous profiles to choose from
    - I select a profile and the selection is highlighted
    - I press "OK" and the pop-up box disappears
    - but if I go back to the "Profile" selection line, only "Managed by Printer" is available.
    What's wrong here?
    Is the inability to select a profile the reason that prints from Lightroom look way to dark when I print them?
    Vick

    Oh, I'm on Windows, XP with SP2.
    The profiles are in C:\WINDOWS\system32\spool\drivers\color
    I used the .exe that was provided by Epson for installing the drivers.
    Nothing fancy, nothing different.
    For Lightroom, I installed it off CD, and got the 1.3.1 update off their Adobe site.
    Any clues there, to solve the puzzle?

  • Disabling color management in canon driver

    Hello
    Can anyone tell me how to disable Color Management in the Printer Driver Dialogue Box for Canon (ip4000) printer?
    Other AI CS4 users must have needed to do this, in accordance with the instructions in the Color management print window when printing in AICS4, as otherwise the colors just dont work when printing.
    As most AI users will know the guidance says "Let Illustrator determine colors", and "dont forget to disable color management in printer driver dialogue box". How do you do that then?
    I have no idea how to find the Canon printer driver dialogue box, and Canon did not seem to know what I was talking about when I phoned them - they said contact Apple or Adobe.
    Grateful for any any advice.

    I don't think it is stupid at all. Even home or small office printers nowadays have the capacity to turn their own colour management on and off. That does not necessarily result in implementing custom profiles though. It is just saying "don't try and match the colours by yourself" basically (although probably a bit more sophisticated in the driver's kitchen).
    As for doing it on a Canon printer (make sure you follow the next steps with Illustrator closed so it can apply to all pictures you will print) :
    - Open the Printing Preferences control panel of your printer,
    - In the Color/Intensity section, select "Manual" and click on "Set...",
    - Check that all colour adjustment sliders are at 0,
    - Go to the "Matching" tab,
    - In the "Color correction" drop box menu, select "None",
    - Close all dialog boxes and you're done.
    It has made a huge difference on my prints with a Canon ip3600 printer. They were way too reddish before, now they are as close as they can be to what I want - provided I don't have nor need any calibration hardware to make highly precise colour calibration end to end.

  • Regarding color picking and color management - can someone, please test this?

    Please take a few seconds to test this and let me know the result.
    This is with CS5 but probably the same with older versions:
    Create a new document and zoom out so that the canvas is smaller than the window.
    Change the Standard Screen Mode color to Custom and choose some color, for example gray that is 60 for each R,G, and B.
    You can do that in the Interface page of the Preferences or by right clicking on the empty area of the window that is beyond the image's canvas.
    Using the eyedropper tool pick the color of that empty area
    Press Alt + Delete to fill the canvas with that color.
    Do you see a difference between the canvas and that area.
    I see a slight difference when the color management preview is on and no difference when it is off (soft proofing using Monitor RGB)
    I have some ideas but it will be great of someone can make a clear conclusion and explanation for this behavior.

    Thanks for that confirmation, Chris.
    Same thing with my apps, though with effort I suppose the colors for the controls and background COULD be put through the color management system at startup time...  Lots more complexity though, and that would kind of diverge with the concept of theme selection, not to mention potentially uncovering bugs in the control implementations...  And, if the user has gone out of his way to set everything to a pretty shade of blue, and along comes a color-managed dialog that's gone greenish because that's what those color values REALLY mean, that would likely be reported as a bug just because it's different...

  • Confused about Color Management in CS5 (Photos appearing differently in all other programs)

    I recently noticed this and it's been driving me crazy; when I view photos in Photoshop CS5 they appear significantly lighter/more washed out than when viewed in other programs like Zoombrowser, Digital Photo Professional or just in a regular Windows folder using Filmstrip mode (Windows XP).  When opening the same photo in both CS5 and Zoombrowser and switching back and forth between the two windows the difference is very apparent...for example, one of the photos I compared was of a person in a black shirt -- in CS5 (lighter/washed out) the folds in the shirt were very obvious, but in Zoombrowser (darker, more contrast/saturation) the folds were nearly invisible and it looked like just solid black.  Now, after messing around with the settings in both Photoshop and in Zoombrowser I've found a few ways to get the photos to look the same in the two programs; one way gives them both the lighter/more washed out appearance and another way gives them both the darker appearance with more contrast and saturation.  My problem is that I'm not sure which view is accurate.
    I use a NEC MultiSync LCD1990SXi monitor with SpectraView II calibration software and calibrate it every 2 weeks using these calibration settings (screenshot): http://img52.imageshack.us/img52/8826/settingsx.jpg
    In the SpectraView II Software under Preferences there's an option that says "Set as Windows Color Management System Monitor Profile - Automatically selects and associates the generated ICC monitor profile with the Color Management System (CMS)."  This option is checked.  Also, when I open the Windows' Color Management window there's only one option displayed, which is "LCD1990SXi #######" (the ####### represents my monitor's serial number).
    I assume the above settings are all correct so far, but I'm not sure about the rest.
    Here are my current default Color Settings in CS5 (screenshot): http://img97.imageshack.us/img97/666/photoshopcolorsettings.jpg
    Changing these settings around doesn't seem to make the photo appear much different.  However, when I go to Edit -> Assign Profile, then click off of "Working RGB: sRGB IEC61966-2.1" and instead click Profile and select "LCD1990SXi ####### 2011-06-21 18-30 D65 2.20" from the drop-down menu, the picture becomes darker with more contrast and saturation and matches the picture in Zoombrowser.  Also, if I select "Adobe RGB (1998)" from the drop-down menu it's very similar in terms of increased darkness and contrast but the saturation is higher than with the LCD1990SXi setting.  Another way I've found to make the image equally dark with increased contrast and saturation is to go to View -> Proof Setup -> Custom and then click the drop-down menu next to "Device to Simulate" and select "LCD1990SXi ####### 2011-06-21 18-30 D65 2.20" again.
    Alternatively, to make both images equally light and washed out I can go to Zoombrowser -> Tools -> Preferences and check the box next to "Color Management: Adjust colors of images using monitor profile."  This makes the image in Zoombrowser appear just like it does in CS5 by default.
    Like I said, I'm confused as to which setting is the accurate one (I'm new to Color Management in general so I apologize for my ignorance on the subject).
    It would seem that assigning the LCD1990SXi profile in CS5 would be the correct choice in order to match the monitor calibration given the name of the profile but the "Adjust colors of images using monitor profile" option in Zoombrowser sounds like it would do the same thing as well.  Also, I've read that Photoshop is a color managed software whereas Zoombrowser and Windows Picture and Fax Viewer are not which makes me think that maybe the lighter/washed out version seen in Photoshop is correct.  So which version (light or dark) is the accurate one that I should use to view and edit my photos?  Thanks in advance for any help or info.

    Sorry for the late reply;
    But before we go there or make any assumptions, it's important for
    you to determine whether you're seeing consistent color in your
    color-managed applications and only inconsistent color in those that are
    not color-managed.  For that you'll need to do a little research to see
    if the applications in which you're seeing darker colors have
    color-management capability (and whether it is enabled).
    I opened the same picture in 7 different applications and found that the 6 of the 7 displayed the photo equally dark with equally high contrast when compared to the 7th application (CS5).  The other 6 applications were Zoombrowser EX, Digital Photo Professional, Windows Picture and Fax Viewer, Quicktime PictureViewer, Microsoft Office Picture Manager and Firefox.
    However, at least two of these programs offer color management preferences and, when used, display the photo (from what I can tell) exactly the same as Photoshop CS5's default settings.  The two programs are two Canon programs: Zoombrowser EX and Digital Photo Professional.  Here's the setting that needs to be selected in Zoombrowser in order to match up with CS5 (circled in red):
    And here's the setting in Digital Photo Professional that needs to be selected in order to match up with CS5 (again, circled in red):
    *Note: When the option above "Monitor Profile" is selected ("Use the OS settings") the image is displayed exactly the same as when the monitor profile is selected.  It's only when sRGB is selected that it goes back to the default darker, more contrasty version.
    So with the red-circled options selected, all three programs (CS5, ZB, DPP) display the images the same way; lighter and more washed out.  What I'm still having trouble understanding is if that ligher, more washed out display is the accurate one or not...I've read several tutorials for all three programs which only make things more confusing.  One of the tutorials says to always use sRGB if you want accurate results and *never* to use Monitor Profile and another says that, if you're using a calibrated monitor, you should always select Monitor Profile under the color management settings...so I'm still lost, unfortunately.
    What I also don't understand is why, when the monitor profile is selected in CS5, the image is displayed in the dark and contrasty way that the other programs display it as by default but when the monitor profile is selected in Digitial Photo Professional it displays it in the lighter, more washed out way that CS5 displays it using CS5's default settings (sRGB).  Why would selecting the monitor profile in DPP display the photo the same way as when sRGB is selected in Photoshop?  And vice versa...why would selecting the monitor profile in Photoshop display the photo the same way as when sRGB is selected in DPP?
    I feel like I'm missing something obvious here...which I probably am.  Again, I'm very new to this stuff so pardon my ignorance on the topic.
    By the way, I find that the way that the non-color managed programs (Windows Picture and Fax Viewer et al.) display the photos is more aesthetically pleasing to the eye than the duller, more washed out display that CS5 gives the photos, but ultimately what I want to see in these programs (especially PS5 where I'll be doing the editing) is the accurate representation of the actual photo itself...i.e. what it's supposed to look like and not a darker (or lighter) variant of it.
    So just to reiterate my questions:
    Why does selecting Monitor Profile under the color management settings in DPP give the same display results as the default sRGB profile in CS5 and vice versa?  (CS5 with monitor profile selected having the same display results as DPP with the sRGB profile selected)
    When using CS5 with it's default color management settings (sRGB), using DPP with the Monitor Profile selected, and using Zoombrowser EX with "Adjust color of images using monitor profile" selected this results in all three programs displaying the same lighter, washed-out images...is this lighter, more washed-out display of the images shown in these three programs the accurate one?
    I noticed when opening an image in Firefox it had the same darker, contrasty look as the other non-color managed applications had.  Assuming that the CS5 default settings are accurate, does this mean that if I edit a photo in CS5, save it, and upload it to the internet that other people who are viewing that image online will see it differently than how it's supposed to look (i.e. in a non-color-managed way?)  If so, this would seem to indicate that they'd see a less-than-flattering version of the photo since if their browser naturally displays images as darker and more contrasty and I added more darkness and contrast to the image in CS5, they'd be seeing a version of the photo that's far too dark and probably wouldn't look very good.  Is this something I have to worry about as well?
    I apologize for the lengthy post; I do tend to be a bit OCD about these things...it's a habit I picked up once I realized I'd been improperly editing photos on an  incorrectly calibrated monitor for years and all that time and effort had been spent editing photos in a certain way that looked good on my incorrectly calibrated monitor but looked like crap on everyone else's screen, so the length and detail of this post comes from a desire to not repeat similar mistakes by editing photos the wrong way all over again.  Again, thanks in advance for all the help, it's greatly appreciated!

  • Funky Banding Seen in PS CS5 Color Management with Some OpenGL Modes

    While experimenting with gradients and large gamut color spaces in response to another post, I came across a peculiarity with displaying image documents in Photoshop CS5 that are using ProPhoto RGB when OpenGL is enabled.
    The test is a simple radial gradient from black to gray using 16 bits/channel and the ProPhoto RGB document profile.  In my test setup, I am using the standard Windows-supplied sRGB profile for my monitor, and the video card is an ATI Radeon HD 4670 running Catalyst 11.1 drivers.  The following are screen grabs using the same technique and software in all cases.
    Exhibit A follows:  This is the display with OpenGL Disabled or Enabled in Basic mode.  Note the perfectly smooth gradient.
    Test 2 (below):  Same document as above, OpenGL enabled in Normal and Advanced modes). Note the slightly colored posterization / bands in the display of the gradient.
    This is not a limitation of my video card's OpenGL implementation, because on this very same system one of my own applications, using 16 bit color management and OpenGL (GL_RGBA16 format specifically) displays a smooth, clean gradient.
    Here is the Photoshop file from which I generated the above displays.  I'd be curious to hear whether you see something like the first or second image when you open it in Photoshop CS5.

    Thanks for the responses, and thank you, Chris!
    Just to clarify (I know Chris understands, but some of the other responses don't list the OpenGL mode)...

    With OpenGL Enabled in Normal mode (i.e., what's shown when you click the [Advanced...] Button in Edit-Preferences-Performance.

  • Color Management in Bridge CS6

    Hello,
    I'm having a strange color management issue in Bridge (64 bit). Essentially, Bridge is not displaying images in either the thumbnails or preview pane using the correct color profile.
    Background: I'm on Windows using a dual monitor setup (both independantly calibrated) but I have the issue even when I use only one monitor. Photoshop has no issues with color settings. I've tried resetting all settings (hitting Ctrl as Bridge starts). I've tried purging my cache and having Bridge generate monitor-size previews.
    The weirdest part is when I start Bridge, for a split second images appear to be in the correct profile, and then Bridge adjusts everything to the wrong color profile.
    Any thoughts?
    Thanks!

    about A:
    I don't get that, I have a custom made monitor profile based on D65 and with or without this profile the only difference one would spot would be in the total picture, this screenshot shows what I see and that is not as much difference between the Bridge thumb and preview (and in the metadata placard you can see they are 16 bit ProPhoto with on top of it the floating PS panel with the same image. It is one picture of one screen, without my monitor profile (and without knowing what happens during the adding process to the Adobe site) or with, the difference between both applications would not change, only the total picture. (or I really don't understand anything anymore about color management )
    The first threshold question is whether you're using a wide gamut monitor. I'm going to assume the answer is yes. The reason it's essential to embed your monitor profile in your screenshot is if you do not have a wide gamut monitor, someone looking at your image who does will be able to tell since the gamut will be smaller than it should be. If you are not using a wide gamut monitor, that would explain why you cannot see the difference. Additionally, whether you have a wide-gamut monitor or not, if you do not embed a profile, the untagged image will appear way oversaturated when brought into Photoshop (this is happening for me) unless I can guess the approximate color space of your monitor.
    Admittedly, if you are using a wide-gamut monitor, then although the image will be way oversatured without a profile (until I assign one), both the Photoshop portion and Bridge portion should be way oversatured by the same amount. However it's not particularly helpful to use guesswork and approximation when trying to narrow down a problem like this. You say "this screenshot shows what I see," but you have to keep in mind you are looking at it on your monitor. Even though your screenshot will obviously look right to you on your monitor, someone looking at it on a smaller gamut monitor won't see what you're talking about.
    about B:
    There you have a point but this was a current project at hand and at this moment there is a bit over saturation in the wood. In real life I also almost never have to deal with the bright colors of your example. I don't want to go again messing my workspaces to create a screenshot for the files you provided but I can assure you I have less to none difference between both files in both Bridge and PS, like I never have seen your problem on my current computer (Mac Pro, 2 x 2,4 6 core intel Xeon mid 2012 and a lot of RAM and SSD etc including ATI Radeon HD 5770 1024 MB VRAM running OSX 10.8.3) as well as my former MacPro with same graphic card - and two others - that I used since 2008 during OSX 10.5 to 10.7 with all used versions of CS.
    Yea, I understand why you don't want to mess with your workflow. I wouldn't either if I were in the middle of a project. But (assuming you have a wide-gamut monitor) if you finish a project and do get the chance, I encourage you to try the ProPhotoRGB color patch in Photoshop versus Bridge. When you really stray from sRGB, you, like me and Yammer, should see a major difference. I suppose there's the possibility that the Mac version of Bridge works differently, but that doesn't seem likely. It's possible you've never noticed the difference before because (again, assuming you have a wide-gamut monitor) you've never been looking for it, or you don't shoot many subjects with colors vastly outside sRGB - things like flowers, dyes, clothing, bright lights, etc.
    And as for the quote, I also never make my choices based on colors for DNG in Bridge, in fact, I always shoot with manual WB set to 5500 K, whether in daylight or artificial light, I just don't bother because I want my colors to be adjusted in ACR and refined the way I want them in PS. The plus side of manual WB is that all colors are off in the same way and can be adjusted in the correct direction in one go for a series
    That's an interesting idea and really illustrates the beauty of shooting RAW - tons on flexibility. And in fact, whether you use manual white balance, or don't, with RAW everything can be corrected or adjusted from a certain baseline by the same amount after the fact anyway.

  • Color management/print profile setting in LR2

    I tried to set a custom print profile in the LR2 Print Module. Specifically, I picked print to JPEG and under "Color Management" I picked "Profile/Other. When I pick other, an empty pick panel pops up. I use Vista 32 and under "\Windows\system32\spool\drivers\color" there are lots of ICC profiles available. How do I point LR2 to the location where Vista stores these profiles?
    Franz

    franz:
    >As described in my opening problem description, I would like to print to JPEG and using the new LR2 ICC profile option provided under "Color Management" / "Profile/Other" and pick an ICC profile.
    I'm not sure what the solution may be. When I chose to print to a .jpg file I see four profiles show up: sRGB, Adobe RGB, and Pro Photo RGB in addition to my normal printer profile. If I chose 'Other' then I see all of the profiles in C:\Windows\System32\spool\drivers\color. If I deselect 'Include Display Profiles' then I only see those profiles associated with my default printer. I know that sRGB and Adobe RGB are installed by the disk that installed my V500 scanner drivers, but those are 'generic' files and may also have been installed by other driver software.
    Note, none of the profiles in that folder were copied there by me. All 31 were installed either by a printer driver installation, monitor installation, or installation of my Epson V500 scanner.
    Quite possibly some were there after I installed the system but before I installed any drivers--I can't say for sure because I never looked at that folder before installing drivers.

  • Color management detective needed!

    I need help with some color management issues I'm having.
    I've noticed that RAW images imported into Aperture (both 1.0.1 and 1.1) look very different than those imported into PS2 via ACR. I've been told that this is simply a result of the different conversion algorithims each program uses.
    However, since I don't see a lot of discussion about that here I began to wonder if the differences I see between PS2 and Aperture are unusual. Also, I've noticed that when I export a RAW file from Aperture or PS2 as a JPEG, the colors of the resulting files look slightly different than they did before export (no adjustments were made in either program). Finally, when I upload the exported JPEGs to a website, the colors change once again!
    This is very frustrating, because I spend a lot of time adjusting the image and finessing the colors... only to see it significantly altered when I put it on the web. I'd like to better understand what's happening here and have more control over the process.
    So I've created a website with various examples of what I'm talking about. I imported the same RAW file into Aperture and PS2 without adjustments. Then I used OS X's Grab application to take a screen shot of how the image appears in each program. Then I exported the image as a JPEG from both PS2 and Aperture, using Adobe RGB as the embedded profile in both cases. (Note: my monitor profile is a custom profile created by EyeOne) Then I uploaded the JPEGs to a website I often display photos on, and then took a screen shot of how both the Aperture-exported and PS2-exported images appear on the web.
    Please look at http://web.mac.com/chriskresser/iWeb/Site/Last%20Roll.html
    So, my questions are:
    1. Why does the color vary so dramatically between Aperture and PS2? Is this normal, i.e. do you experience the same thing? Is there something I can do about it?
    2. Why do the exported JPEGs look different than their RAW master's? Again, is this normal and is there anything I can do about it?
    3. Why do the JPEGs uploaded to the web look different than the JPEGs opened in Preview or PS2?
    I've tried to standardize my color workspaces as much as possible, but I'm not sure I've done it correctly. In Aperture, onscreen proofing is off and I'm just using the default colorspace (which I understand is a wide-gamut RGB?). In PS2 I am using Adobe RGB as the working colorspace. My monitor profile is the custom calibrated Eye-One profile.
    I really appreciate any help you can offer. I'm pulling my hair out trying to get this straight.
    Thanks,
    Chris

    Thanks to everyone for helping me figure this out.
    Let me make sure I understand. In Aperture, when I go to export a JPEG for web use or printing from another application with my home inkjet I select sRGB as the color space.
    In PS2, I use Adobe RGB as my working color space, but when I save a JPEG for the web, I change the profile to sRGB before exporting. Do I use the "Edit>Convert to profile..." command for this? Or should I be using sRGB as my working color space in PS2 since most of my output is for the web and home inkjet? (There are occasionally times I send files to a printer for output, though).
    The Aperture RAW and PS2 RAW look significantly different on my monitor too, not just on the web. I'm using the default ACR settings - do you think they need to be customized for my camera? I see what you are saying... the ACR RAW does look much brighter than the Aperture version and kind of washed out. Not sure how to fix that though...

    Here are some of the technical specifications for the books, cards, and calendars. I hope this gives you an idea about their quality and form.
    BOOKS
    All iPhoto books are printed using acid-free paper for long-lasting image quality. The photos are printed at a high resolution (300DPI if you use iPhoto 6). There is no external modification--such as sharpening or contrast adjustment--of the photos; what you see in the application is what is printed in the book.
    Hardcovers Books
    The cover is hard-bound and covered in linen. You select the linen color during the book-ordering process. The hardcover books have a solid, stiff binding that is glued and crimped. The internal pages, measuring 8.5 x 11 inches, are printed on McCoy 100# Text Gloss paper stock.
    Softcover Books
    The softcover books come in three sizes:
    - Large 8.5 x 11 inches
    - Medium 6 x 8 inches
    - Small 2.6 x 3.5 inches
    All of the softcover books have internal pages that are printed on McCoy 100# Text Gloss paper stock. The large softcover book has a white cover (Kromekoteplus Folding Cover, 16 point) with a cutout on the front that reveals the cover-page photo in the book. The covers for the medium and small softcover books have the cover image and title printed directly on the cover. All of the softcover books have a glued binding and feature a thick cover of McCoy 100# Cover Gloss paper stock.
    CARDS
    All cards are printed on McCoy 120# Silk Cover paper stock. The postcards measure 4 x 6 inches, and the greeting cards measure 5 x 7inches.
    CALENDARS
    All calendars measure 8 x 10 inches and are printed on McCoy 100# Silk Cover paper stock.
    To ensure the best print quality, we have chosen to use Kodak NexPress technology. The press uses a dry toner, which is fused to the surface of the paper. Please see NexPress' site for more information:

    TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto database file and keep it current. If problems crop up where iPhoto suddenly can't see any photos or thinks there are no photos in the library, replacing the working Library6.iPhoto file with the backup will often get the library back. By keeping it current I mean backup after each import and/or any serious editing or work on books, slideshows, calendars, cards, etc. That insures that if a problem pops up and you do need to replace the database file, you'll retain all those efforts. It doesn't take long to make the backup and it's good insurance.
    I've written an Automator workflow application (requires Tiger), iPhoto dB File Backup, that will copy the selected Library6.iPhoto file from your iPhoto Library folder to the Pictures folder, replacing any previous version of it. It's compatible with iPhoto 08 libraries. You can download it at Toad's Cellar. Be sure to read the Read Me pdf file.

  • Color Management Settings in Windows 7/Vista

    I know this is not exactly the right forum to ask, but I also know that some people very knowledgable in color managment read/write here:
    Can somebody explain to me what the setting of "Device Profile" in "Windows Color System Defaults" really does/affects:
    I've searched the web and found nothing but questions ...

    Noel:
    I have custom calibrated with an Eye-One puck.  I was just searching around looking for a way to verify that indeed the profile was in place, concerned that it might not be, and came across this advice in the links attached to my first message. But my ultimate goal was to verify that indeed I had my monitor profile in place.
    After reading through the links, although I did tick the "Use Windows Display Calibration" I did not push the "Calibrate Display" button, recognizing that this leads to a visual calibration routine.  In the links I attached, and also:
    http://www.pusztaiphoto.com/articles/colormgmt/win7/default.aspx
    the authors are suggesting that ticking the "Use Windows Display Calibration" is a necessary step to ensure that your custom profile is loaded and remains loaded.  Although I admit that this seems illogical (hence my question) the author of the article linked above asserts that checking this box does not relate only to a visual calibration via the "Calibrate Display" button.  Indeed, in referring to the Microsoft description of this module, where it says that"Windows profile loading" should only be used in conjunction with the visual calculation function his advice his is to "[i]gnore it," indicating that the people who wrote the help article misunderstood its function.
    And, as noted above, after trying this I did notice a profile shift with my custom calibration in place, so it did pique my curiosity. In the last analysis however my ultimate goal is to know that my custom profile is properly loaded.
    Any thoughts on what is the best way to do that?
    Thanks,
    Brian
