About color profiles

Hi Friends i am Murali From india.
i have one dout friends
i make on File From Photoshop.
using color profile : sRGB IEc
i need to output for CMYK. so i am convert to CMYK
that CMYK Image Is added Darkenss. so the quality is not
well.

This is probably the effect of your now calibrated monitor vs. the uncalibrated one.
Often uncalibrated monitors show highly over-saturated colors. It looks very rich and flashy and people are wowed.
But these over-saturated colors cannot be printed and do not reflect the true state of the image data.
When your monitor is calibrated properly it will display the colors as they should be.
When you chose sRGB all the colors - particularly the reds and greens - will appear more saturated. That is the effect of this color space that is much smaller than Adobe RGB or Pro Photo RGB.
LR will automatically find and select your calibrated color profile if it is saved in the right place / folder.
And you can't change that. There is no provision for a different color space in LR.

PS: As Pete and other posters have said already: Set the white point of your monitor to 6500 - that is the accepted standard. Don't choose sRGB to make your photos look good. Rather work with a calibrated monitor and then edit your photos in LR to your liking. You seem to think that your photos are a given and you have to adjust your monitor to make them look good - that's not how it's done.

One again about color profiles and lightroom

I have wide gamut monitor (nec pa271w) and I tried to calibrate it. After calibration it created new color profile and make it default in windows color managment. But now all pictures in Lightroom are not so colourful as they were before. If I choose srgb(default profile for windows) the colors become as they were before calibration but in this case I see srgb color space and not full color that my monitor can produce. I read articles about calibration but didn't find how to solve the problem with lightroom.

Confused about color profile support in PNG

NOTE -- you have to hover over the image to see the real images. The images embedded in the webpage have their profiles stripped -- just like photoshop does! Interesting.
I ask a similar question on this before, but couldn't give a satisfactory demonstration of how photoshop doesn't support color profiles in png's.
But now I have a great one.
Picture A: this is with the correct color profile and displays correctly in firefox and probably other browsers -- also displays correctly on windows desktop and in large-icon view.
Ok, anyone who doesn't believe me, grab that image and try to read it into photoshop...
I do, and get no warning on profile mismatch like I do on jpg's or tiff's:
photoshop strips the existing profile and adds sRGB which isn't the correct profile.
This is how photoshop transforms good colors into bad:
Completly screwed up.
I have had multiple people notice how my png saved images from photoshop had "off" or bad colors -- usually washed out in comparison w/my monitor profile.
I can get 'ok' results if I flatten the image and *convert* my existing profile to sRGB -- and I usually get
something that looks 'acceptable'...though the jpg's render in accurate color.
Basically, photoshop can't read or write png web images. and maintain color fidelity unless they have no profile. Even if they have an sRGB profile, I usually get washed out looking pics if I don't strip it but let adobe convert it.
In googling for my own problem, I found references to this problem in Adobe Photoshop going back to 2002.
Why does adobe refuse to fix this? It's horrible.
They could fix it with a file plugin for existing CS5-6 users, but it really needs to get fixed and Adobe needs to stop ignoring this problem.
:-( I find this extra depressing because I prefer to distribute my pictures losslessly in png, but with photoshop, I'm left with lossy jpegs to get accurate color reproduction.

How did the SFW thing even come up?? When I embed profiles in jpg and tiff, I do it as part of the File Save or File Save As dialog. I can choose what profile to save it with -- and I usually save it with my currently calibrated monitor profile -- as that color profile is what was used to create the picture. Why would I want to convert them to some other profile?? Only thing I have needed to convert have been PNG's because it doesn't embed my monitor profile in the PNG the same way jpg and tiff do.
If it did, png's would look the same as jpgs and tiffs... but the jpgs and tiffs have the full depth of color and look the same as they do in PS. png's look washed out because -- it's been my belief that PS is not storing my profile in the png, but setting a bit in the file to use the sRGB profile.
AFAIK, PNG provided for a sRGB profile-compat bit -- so images that were compat w/that profile could just set a bit rather than including a profile. I see no evidence that PS is saving my monitor profile with the PNG.
My 'settings' for RGB are to convert to working RGB profile which is my monitor profile.
I do have it set to ask me abou profile mismatches on opening or pasting.
Since I don't get a 'this document has a different color profile than the working space'
message when I edit most png's, I assume it has none. Thus from my settings
it should autoconvert it to my monitor profile and save that on save -- which seems to be what happens when I save as jpg or tiff (or I can check off the box to save profile...but I usually don't).

Color Profile Problem

Hey, I have a question about color profiles.
If you go to system preferences -> display -> color, and use "Color LCD." Now click on "calibrate," use expert mode, and click continue all the time. does the screen change at all?
Mine seems to become greener, is that a problem?

Hi haginile,
When you start the calibration did you follow the instructions and move the sliders around until the Apple icon in the box looks neutral gray to you before hitting the continue button?
Jrsy
Actually I forgot to mention that you need to adjust both left and right sliders through each of the five calibration steps before continuing to the next step.

A general question about JPGs, color profiles and the web.

(Didn't get much help in the PS forum, so I'm gonna try this here.)
I save a website background image in Photoshop with its color profile (in this instance, Adobe RGB 1998).
When I view the image in IE (latest), it looks the same as it did in PS.
When I view it in Firefox (latest), it comes out darker.
I'm guessing this has something to do with one of the two browsers taking the color profile into account, and the other not.
What is everyone's solution to this problem? Should I not be including color profiles with my JPGs? And if that isn't the problem (ie, I should keep doing it), which is the color profile I should be using in RGB?
I keep hopping between Adobe RGB (1998) and sRGB 2.1 and can't decide which one to adopt once and for all.
Thanks.

You are correct. The colors differ from IE to FF because FF and Safari use the color profiles found in your images.
You might like the discussion found on Usability Post: http://www.usabilitypost.com/2008/07/30/photoshop-color-profiles-for-web-images/
I've been using sRGB 2.1 for a few years and have had no major issues with it.

IPhoto fix that worked for me (Coregraphics & Adobe Color Profiles issues)

Ok, I posted a few days back in reference to getting help with my iPhoto. I do apologize on the fact this is quite the long post but maybe it will be easy to understand for those who are like me and not all that computer literate. I searched all the discussions and used all the different advice from different people but had no luck. I was able to FINALLY get iPhoto up and running again last night after doing just a few simple things. Please note that this may not work for everyone. Also please note that I AM NOT an expert in dealing with computers and working with computers. It's just that my ADD kicks in when something needs fixing and I won't stop till its finished. Below are a few lines from the crash report that I was getting each time I attempted to open iPhoto from my Macbook Pro Late 2011 running 10.8.3.

-Run and attempt to repair any Color Profiles that may need to be fixed. There were 4 that could not be fixed for me. Locate these profiles and move them to your desktop (Note: I was still able to open and use all applications in my Adobe CS6 Master Collection after moving these profiles but you may want to check just to be sure if you are using Adobe).
-Even though I had done this many times, run the Disk Utility App in your Utilities Profile and Verify and Repair any permission needed (For me, I had none at this time that needed to be repaired).
-Next, I did an Apple Hardware Test. For me and the model Macbook Pro I am using, I had to restart my computer and when the screen went black for me at restart about the time the start up sound is about to come on, I pressed ALT-D. On some models you just have to press D. I did disconnect everything prior to doing this except the power cord and the Internet. I did a full AHT test that took about an hour or so. If you get an error code, be sure and right it down whereas your issue may be something different than mine and this will not apply to you. There were no problems from the test and then restarted the computer.
-At restart I decided to get into the OS X Recovery by pressing Command-R to either start from scratch or find some other way to fix the issue because I was tired of racking my brain on this and was about to throw the computer in to the wall.
http://support.apple.com/kb/HT4718 For help or questions on the OS X Recovery Process
-Once in the OS X Recovery from the Mac OS X Utilities Pane, I selected reinstall and then I selected my current Hard Drive. Luckily by doing this (not that I was aware or anything, but none of my files or folders were deleted and it only reinstalled Mountain Lion and whatever else it needed)
-This process took about an hour and once finished, I restarted my computer
-I logged back in to my account but did not attempt iPhoto at this time. Instead I immediately checked to make sure that 10.8.3 was what was reinstalled back on my Mac. I then checked for Software Updates which I had a few and installed these updates.
-I then went back to the Disk Utilities App from my Utilities folder and Verified the Disk and Disk Permission. To my surprise, many of the files that were in the iPhoto crash thread (posted above) were now showing up as needing to be repaired. I repaired what needed to be repaired.
-I verified all my Color Profiles to make sure none were showing up again (which there were none that needed to be repaired)
-I did a check check of some Adobe CS6 Apps just to verify they were opening and working correctly
-I restarted my Mac (Once again) and logged back in. I opened up iPhoto and everything worked and is working PERFECTLY. I then re-connected my printers and my Time Machine and performed a back up before importing photos back in to iPhoto. I DO WISH NOW THOUGH THAT I HADN'T DELETED AND RE-INSTALLED IPHOTO but it is nice being able to start over and organize iPhoto a little better than before.
I am sorry this is such a long post but for people like me who are not professionals in the computer department, sometimes it's good to "dumb" things done so that us "average joes" can understand a little better. Hopefully this will work for those who are having issues like mine. Thanks for all the help from everyone from my previous posts.

Tom:
To help prevent loss like you experienced see the tip at the end of my signature.
Do you Twango?
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.

Picture color profile in Lightroom vs Photoshop CS2 editing

Hi all, I hope someone can solve this for me.
When I'm viewing picture in Light room, all my pictures are a bit warmer ( have a yellowish tint to them ) compared to when I view them in Photoshop CS2. The same is true if I view them in other programs. This is true for all my picture file type (jpg, tif or raw). I get the feeling that it's Light room that in the wrong in how it displays the picture and not the other programs. Using the warms tool to make the picture a bit colder, only adds a bluish tint to the image which isn't even close to what it looks like (unedited) in Photoshop.
I get the feeling that Lightroom does something to the picture, or uses some sort of color profile, driver that other programs don't use.
Is there a way of changing this?

>When I purchase these ADOBE products I expect them to JUST WORK!!!!!
Unfortunately, when Microsoft, Dell and others enter the fray it's no longer up to just the Adobe folks. Differences between Photoshop and Lightroom are almost always due to a corrupt monitor profile. Adobe has nothing to do with that.
>I dont wanna have to be worried about corrupt profiles yada yada yada!!!
I just want to be able to do my color correction and exposure corrections in Lightroom export as a High Res Jpeg and then do the remainder of my work in Photoshop and have them both look the same.
If your screen is correctly calibrated that will be the case. Unfortunately if you want to do color sensitive work on a computer with a typical monitor, you have to have a rudimentary understanding of profiles and color management. There is unfortunately no way around it. This is no different from traditional color photography where you have to understand what different film, different filters and different development do to your colors. The terminology is just different.
>How do I fix this and please go through it STEP BY STEP BY STEP!!!!
I am not one for the computer lingo....
OK. I'll assume first that you have no hardware calibrator and that you are on windows:
1. Make sure your Photoshop color settings are set up to respect embedded profiles. See the
first screenshot in this post(ignore everything else as it is no longer relevant in LR 2).
2. Open your monitor's properties panel, click on advanced and go to the color management tab. Delete any profile you see there. This is the culprit. Probably a bad profile got installed in some driver update for your graphics card or your monitor.
3. Restart Lightroom and Photoshop and that's it! You'll have corresponding colors. You are however, cheating yourself as your monitor is completely uncalibrated. This is how 99% of computer users run their monitors.
So here is what you should be doing if you care about your color and matching to print and making sure that others see the same colors. Even though hardly anybody calibrates, the only way to get a good average correspondence is to calibrate your monitor and use color managed apps. This sequence is valid for both macs and PCs
1. Do as above step one and make sure Photoshop is set up correctly and then go out and buy a hardware calibrator (or order online). They can be had for <$100 for pretty good ones. Look for example for Spyder2 and Huey Pro.
2. Calibrate your screen following the instructions from the software
3. Restart Lightroom and Photoshop. Now you'll have identical but correct color.
If you have a mac, you can cheat slightly and use http://www.computer-darkroom.com/colorsync-display/colorsync_1.htm instead of hardware calibration. You cannot expect very good correspondence between monitor and prints though with that method.

Converting RGB to DNG without affecting color profiles

Hi guys
I'm working with the DNG SDK in C++ for some time now. I need to be able to take a raw RGB (not camera raw) and convert it into a dng file. After playing arond with it for a few days, I realized creating the camera profile drastically affects the resulting dng image.
I can't seem to produce a dng file that was identical to the input source. My picture appears very washed out and I end up using the adobe color profiler to try to bring the image back close to it's original color.
I'm trying to find a way to produce dng files without the need to affect the colors in any way, the resulting picture should be bit identical to that of the raw RGB input file.
I'm not even sure if I can do this considering the usage of the dng format.
UPDATE
I've realized that my program is loading the RGB buffer into the fData of the stage3 image object. I have a feeling I need stages1 and 2 but i'm unsure if I need to and if so, then i will probaby need a source DNG to produce those stage1 and stage2 unless I can get stage1 or 2 from stage 3 (appears it works vice versa).
I'm able to do the reverse (DNG to RGB raw) by extracting the buffer from the stage3 render. but in this case, all the metadata has been filled in by the input DNG. However, going from RGB to DNG, I don't have the metadata to fill into stage 1 and 2.

My understanding of the JPG is only middling. I thought I understood that it uses anchor pixels and either a translation table of some sort or difference mapping, using 8 bits per piece of information.
If that were the case, surely changing the translation from CMYK to RGB would be fairly simple.
In this case, the usage is Ebay and they only accept JPG, PNG (and maybe BMP and GIF, I didn't look that closely), but require RGB. I was actually quite surprised to find that JPG allows CMYK since, as you say, anyone dealing with CMYK is going to be dealing with commercial printing and few people who deal with commercial printing would play around with JPG.
I always stick to TIFF or PSD for workflow, but JPG is popular for a reason - when it comes to web, JPG is the only format that can deliver manageable file sizes with full-screen or "large" images for web. Our top level banner photo is 2590x692 and needs to be under 400kb for sane download speeds. PNG couldn't touch that. Even with the aforementioned 1800x1200, PNG is nearly 2mb, while I can maintain very decent quality with a 500kb file with JPG that works well for 'zoom in' type usage.
So there's no way around JPG. It's just annoying that the first person to touch a random selection of the pics was primarily an Illustrator user and saved *some* of the pics in CMYK mode.
It's like that old story about the farmer who didn't want anyone to steal his watermelons, so he cleverly posted a sign "None of these watermelons are poisoned", only to find a note the next day saying "Now, One of these watermelons is...".
Far more work to fix 'some' of the images compared to just doing it right the first time.
But then again, for workers like that, if you can't trust them with an easy job, you could hardly trust them with more complicated jobs...

Embedded Color Profile is Lost When Content is Published to Web or Dragging Image Window on Desktop

Hello, Everyone. I have a question that I have struggled to crack on my own to no avail. I hope someone here can help.
I am trying to publish some images to the web using color corrected monitors, RAW format, and a color checker passport to create a perfeect color profile. Here are the technical details and my workflow.
Camera: Canon Rebel EOS Xsi
Format: RAW + L
Color Space: sRGB
Color Checker: X-Rite ColorChecker Passport
Monitor Calibrator: Spyder4 Pro, fully updated software
Computer: Lenovo T420 ThinkPad
Second monitor: Samsung LED SyncMaster SA350 (NVIDIA)
Photoshop: v12.1 x64 (CS5.5)
Photoshop Color Settings: Custom North America Web/Internet
RGB: sRGB IEC61966-2.1
CMYK: U.S. Web Coated (SWOP) v2
Gray: Gray GAmma 2.2
Spot: Dot Grain 20%
Policies
RGB: Preserve Embedded Profiles
CMYK: Preserve Embedded Profiles
Gray: Preserve Embedded Profiles
After importing the image into Photoshop, I make sure the RAW space is set to sRGB IEC6 1966-2.1
Use the eyedropper to select a neutral color one step away from pure white on the RAW image of the color checker, create and set the custom white balance.
set the white balance
Export the image as a DNG
Load the DNG into the X-Rite ColorChecker Passport software to create a color profile
Back to Photoshop
Open the RAW file
Set the white balance to the custom profile created above
Set the color profile created with X-Rite
Open the color-corrected image in Photoshop (see color setting above)
Save as JPEG
Publish
First, everything seems to go great throughout this entire process, until I see the image on the Web: LINK. Once published, the image has a very noticible golden-yellow tint to it. The color-corrected image looks great on both color-calibrated monitors, in RAW and JPEG. Absolutely perfect. After noticing the ugly yellow tint in the image I posted to the Web, however, I became aware of a couple more weird things.
1) When the JPEG was open in Photoshop and I moved the window that contained the image around on my second monitor, the image immediately took on that golden-yellow tint: you can see a screen shot of the color corrected image on my Samsung (bottom) and the yellow version of the same image created when I drag the window around on the Samsung (top) HERE.
2) When opening the X-Rite software, I got a warning saying that the laptop monitor had been calibrated, but that the Samsung had not. I got this error even if I calibrated the Samsung monitor right before using X-Rite. Also, the monitor is definitely calibrated, because the images look great, and the colors match what I see on the laptop.
3) Recently, I noticed that when waking my computer from sleep, the Samsung monitor no longer holds its Datacolor (Spyder4) calibration.
I thought the problem I was having might be due to the monitor, for the reasons stated above. However, I later noticed that when I open the color-corrected JPEG with the default Windows image viewer, it retains the color correction settings. The image looks fantastic, and doesn't lose it's color profile when I drag the window around. Also, there seems to be less color loss in the Word documents and PDFs I included this image in: LINK.
I checked this with several more images, and the results are the exact same. I scoured the Web as best I could, but my problem seems to be pretty unique. Does anyone have an idea what might be causing this?
Thank you!

Thank you, twenty_one, for taking the time to read my post and put up a reply. I am going to rebuild my question and post it again here. But first, to answer some of your points:
1. A raw file has no color space, until it's opened into one in the raw converter. So this is controlled in ACR, not the camera.
I just wanted to be as thorough as possible. One of the steps I took was to set the Color Space setting in my camera to sRGB:
2. White balance has no bearing whatsoever on camera profiles. A profile is not for white balancing, it's to account for the spectral distribution of the light, which is something else. You make the profile and assign it in ACR, then you white balance for processing.
I know. I wasn't talking about white balance in my camera. I set the white balance here:
I grabbed the color for setting the WB here:
3. If you get a message about monitor calibration upon opening the camera calibration software, something is seriously confused. The two have nothing to do with each other. No relation whatsoever.
Camera calibration software?
4. A corrupted monitor profile will only show up in Photoshop and other color managed software. Other applications that are not color managed will not use the profile and are not affected. So find out which apps are and which aren't before drawing any conclusions.
Agreed. That's partly what I am trying to get help with.
5. Your links don't work, and in any case clicking on links is something most people including myself dislike. It's much better to insert screenshots in the post, by using the camera icon in the reply box.
I'm new to this forum, so this is helpful to know. This image shows the color-corrected image (bottom) on my Samsung. It looks exactly the same in the same window on my laptop monitor. When I move that window around on my Samsung screen, it turns gold (top). The image, when posted to the web, looks *similar* to that gold color.
So let's say I only use Photoshop on my laptop, which is not displaying any colors. Do you think the golden hue problem will go away?

Bad ramifications of color profile used in previews

It seems that Aperture's choice of color profile for its previews has some rather wide implications. In a RAW workflow, previews are assigned an Adobe RGB profile. In a JPG workflow, previews aren't generated at all at first (which makes sense - no need to create a JPG from a JPG), but they are created once you edit a photo. Then once again, the preview is assigned an Adobe RGB profile, irrespective of the color profile of the original photo. This all kind of makes sense. Presumably, Adobe RGB is the same as, or close to, the color profile Aperure uses internally.
The problem comes when photos are "shared". With the Aperture preference set to "Share previews with iLife and iWork", Aperture generates an XML file that can be used by external programs. This XML file points the external program at the previews (or the original in the case of an unedited JPG). Then photos can be picked up in various places:
* In mail.app via the Photo Browser.
* In any app via the Media section in Finder.
* On an Apple TV via the "Choose photos to share" option in iTunes.
BUT - all these photos (with the exception of an unedited JPG) will ALWAYS have an Adobe RGB profile. This is generally not good, since the photos will display badly in any app that isn't color managed. Unfortunately, this seems to apply to Apple TV. Photos there have the typically subdued look of Adobe RGB when not color managed. The situation actually gets worse with JPGs. An unedited JPG which originally had an sRGB profile will display fine, but as soon as you edit that photo in Aperture, it willl display badly because now iTunes/Apple TV is working with an Adobe RGB profile. I've done tests and it's painfully obvious.
Anyone else come across this? I'm not sure what can be done. Maybe having an option to generate proviews using sRGB would be good, but that might involve too much processing in Aperture when it's continually generating previews as you edit.
Thoughts appreciated!

The export settings don't have any effect on the problem, unfortunately. What preference are you referring to? Do you mean the Import "tab" in Aperture prefs? That just governs what Aperture uses for its initial preview. it will now, by default, use the preview that is embedded in every RAW file to speed up processing. As soon as you look at the photo, even without editing it, it will then generate its own JPG preview (with Adobe RGB profile).
I haven't received any other feedback about this problem anywhere, which is surprising to me. I think I can only post the problem through Apple feedback, and hope for the best. It seems that, in the meantime, the only course of action is to export everything you need to display properly on an AppleTV, and re-import those JPGs into Aperture (or iPhoto) so they can be displayed via iTunes. A royal pain!

Acrobat 9 Pro color profiles?

here is my situation:
I create multipage mockups in Illustrator (all of my Adobe software is Creative Suite 5 Design Premium running on Win7 32bit [I wish it was 64, but printers don't like it so.. yeah]) and after creating them , i then save them to a modifed PDF Preset PDF file.
My problem is this: All of my color profiles are synched via Bridge for uniformity. I know this doesn't apply to Acrobat (though it should, and if it does it doesn't say it anywhere that i've found). The original Illy Document has a profile embedded and the colors look and print out just like i need them to. the pdf version however seems to not like that idea and appears to have different profiles for each page. I have made sure that the color profiles are included and no color conversions happen.
Why am i getting this?
I can provide a sample set of files so you can hopefully see what i see if you need them.
I do not know that much about any advanced features of Acrobat, so it may be setting that I'm not aware of or something like that. Color is also not a very high priority (though i really wish it was) in my workflow and thus my understanding of it is also fairly limited. Color theory in college doesn't count i don't think

This may have nothing to do with your problem, but -- at least with Acrobat 8, there is a 100MB limit to the scanned image. Are you trying to scan something larger than that?

How to get paper color profiles when printing from Acrobat

Hello,
I've been in trouble trying to print with specific paper profiles from Acrobat.
I'm running on mac os 10.8.5, and the latest version of the suite (Acrobat XI).
My printer is an Epson 3880.
I can print ok using my paper profiles when I'm printing from Photoshop; the paper profils show up in the printer box,
and I can choose from my different paper profiles, some of which I've installed recently, non-Epson papers.
But those paper profiles don't show up in the menu when I print from Acrobat…
Any hints why I can't reach those?
Thanks in advance for any help,
Keth.

Are you talking about the color profiles? If so then:
1. Go to File>Print
2. Click the Advanced button
3. Select Color Management from the window pane
4. Select the Color Profile from the Color Profile pop-up menu

Iphoto and color profiles

I know this is a tricky topic, but I'm trying to nail it down.
The colors of the prints from iPhoto on my Canon Pixma iP4000 inkjet do not match what I see on my ibook G4 LCD monitor on my ibook. I do most of my editing within iPhoto (although some in Elements). What color profile do you suggest I use with the display--I've tried Color LCD and sRGB (both types) but the colors are still off from the printed output.
The photos generally have sRGBIEC61996-2.1 embedded in them. The output is better with Colorsync on than off, but I still get a yellowish cast on my printed output. I know I could adjust picture by picture, but I need a more comprehensive solution. I'm also not sure anymore how files sent to photo processors and Apple books will turn out compared to my display.
Many thanks for any advice you could give. BTW is there any way to find the kind of embedded profiles in a picture from within iPhoto 6, as well as its current (edited) resolution and size?

dhollister:
You probably know more about it that I but in iPhoto's Advanced preferences section there's a checkbox to Add ColorSync Profile (upon import). I've not gotten a good handle on it but you can experiment with some files with that option turned on and off to see if it will correct your problem.
Just ran a test with an image file right out of my Canon camera with the Camera RGB profile. I imported that file with and without that check box selected and didn't see any diffference. Checked the EXIF fields with another application, iView MediaPro, and both reported just "RGB". The user may have to add the particular profile to the file before importing to the the profile they want. I added with iView MediaPro the sRGB and the sRGB IEC6 1966-2.1 profiles and saw little difference when comparing them on screen. I then added the Adobe RGB 1968 profile and then saw a more saturated color in the image. All comparisons were made in iPhoto in the full screen mode.
I know Apple uses the sRGB profile for it's printing, books, etc. so have set up my Photoshop CS2 preferences to use that profile. I've also set my monitor to use the sRGB profile. The books I've ordered have been good color wise so I guess it's working for me.
Hope this information has been of some help.

What color profile for digital printing?

Under color settings in InDesign i only find profiles for offset press but what color profile should i use if i want my document printed on a digital printer?

indewarry wrote:
i just find it strange that there is no 'standard' profile for printing for digital press. All profiles are for conventional press.
Like conventional presses, digital equipment uses a range of inks and papers, so there is no single profile that would always be correct, and the press operator can often calibrate the equipment to one of several differnt standards. I use a printer that offers both offset and digital (using an HP Indigo) printing, and all of their equipment is calibrated to GRAcol.
The fact that the printer couldn't tell you the correct profile is a big red flag shouting that they don't know anything about color management. Don't expect good color fidelity, and insist on a contract proof.

Print driver/color profile problems after 2.0 update

Since I updated to the latest version of aperture 2 I have had problems with printing on my canon 5200R printer. The coloring is way off, as if aperture does not seem to recognize the canon print drivers or color profiles. I have read about printing from another program but was so happy with color quality using aperture 1.5, is there a fix for the current problem?

Bump.
