Colour calibration which is correct PS, Windows viewer or IE?

Hello.
I have a iOne display 2 calibrator, Im using Photoshop CS5, and viewing pictures in the standard windows photo viewer.  Im producing digital art to be primaraly viewed on the web.
Recently Iv been working on a project within Photoshop to get the best post work done. Today I calibrate my monitor  and found pictures viewed within PS different from windows viewer by the fact that PS apears to have more contrast and Saturation.  I open the same image in Internet explorer and its different again by being even more saturated plus contrast, which one is correct?
In Windows Color Managment The ICC profile made by ione is set to the monitor, and in Advanced tab the Device profile is set to sRGB IEC61966-2.1, everything els is system default.
Within PS iv set the Colour settings to the ione made profile.  Using Proof for RGB monitor shows no difference.  If I have PS, IE and windows viewer showing the same image at the same time, and I change the ICC profiles, all three images are effected, yet non of them match?
I havent a clue whats going on, and what app is using what colour managment.  I want to use PS to get the best ballance for the Web viewer, the problem is which is correct?
Thanks.

Yes, this is all normal. IE will usually be off a bit. And proofing to Monitor RGB is a simulation of how it will look without color management.
The point that Noel makes above, about the difference between calibration and profiling, is an important one. It confuses a lot of people at first.
Another thing that might help keeping the concepts of color management clear, is this: Don't focus on the individual pieces, the individual profiles. Focus on the process, the relationship. The important thing is the translation between the profiles. The profile is only there to facilitate that translation.
So you have a source profile, which in this case is the document profile, sRGB. That's a standard color space. Then you want to display that on your monitor, which does not have a standard color space, but a rather irregular one that is specific to that particular monitor.  That's why all monitors display differently.
The calibrator measures the monitor and makes a full description of its particular characteristics (after it has been calibrated). This is the monitor profile. So what happens then is that the source profile is converted, translated, to this destination profile. The result is that the file displays correctly, on all calibrated systems, because they all have this sRGB file translated to their individual monitor profiles.
So you can see it matters which profile goes where, and that the two should not be confused.
Iv never even known untill today that a profile is or can be embedded into the image itself, or even how iv done it?
The document profile is normally embedded by Photoshop. But you can choose to not embed it, either in the Save dialog or through Save For Web (where the default is to not embed). There are checkboxes for this.
If you don't embed, color managed applications will either assign a profile or not do anything at all, just send the numbers straight through.

  • Printer Colour calibration

    I have an officejet pro K8600 running under Windows 7. I know this would not be considered a true photo quality printer but the output is good enough for my purposes generally.
    The only caveat is that when I print on photo paper the results are always darker than the screen display. The screen itself has been calibrated with a Spyder (which has corrected the yellow tinge in Photo Viewer). Is there a method published to calibrate the colour rendition of the photo output so I don't have to over lighten the pictures on screen to get a good print?

  • Prints made by LightRoom to dark, made by Windows viewer Ok

    I have noticed that the colours of photos, made by using the print option from LightRoom, are much to dark and dull.
    And before anyone start thinking of using the right color profile for the printer, read the line below:
    When the same picture is opened in the default viewer of Windows Vista and print is pressed, the colours do match the colours of the screen. (± 5%)
    - The used picture is a non adjusted RAW picture made by an EOS 5D and TIFF a printer file which is used to calibrate the printer.
    - LightRoom version 1.2 (Problem also noticed in 1.0 and 1.1)
    - In LightRoom all options to adjust the picture are set to Off
    - LightRoom is the colour correction set to be handled by the printer driver
    - The printer driver is set to ICM, NO colour correction
    - The monitor is calibrated.
    - Printer = Epson R2400
    So when the picture is printed by LightRoom the colours are much to dark and dull, and when using the simple Windows viewer, the colours of the photos are printed correctly.
    Anyone have a suggestions??
    Thanks in advantage

    Hello.
    I am happy as a child, finally seems to have found a solution on the "dull colors" problem at least for my LR 1.2.
    My printouts from my PC (Vista based) LR to my HP all-in-one (network connected) was a disaster. Dark muddy colors. General recomendation was to use "managed by application" option in LR. As no profiles were installed, available from the install CD or from HP I more or less gave up.
    I borrowed a laptop (XP) and installed LR and installed drivers for my HP printer. Voila! Fine printouts, not like the ones I get from my Vista based LR. I tried to select "Profile other" (=managed by application) option and suddenly found ICC profiles for my HP printer. I did a test printout using "managed by application" selecting appropriate profiles, with same good result. Looked in Windows/System32.. catalog and found the HP printer profiles. Looked in my Vista and found other profiles but noone for the HP printer.
    So, for some reason the HP installation program did not managed to install profiles correctly in Vista. So I copied the profiles from XP to Vista and mapped them in the Vista color management tool to the printer. Now I can select the files in Profile others (=managed by application) and get acceptable prints. After changeing the option in the printer driver to "Managed by application" instead of using Prophoto the result was even better (just as stated in the manual).
    Hope this help some of you to solve the "dull color" problem. If anyone of you need profiles for HP 3210 all-in-one pls give me a hint and I will send the profiles to you. If you have suggestions for profile for handling matte paper on HP 3210 I am interested to hear from you.
    Good luck.

  • Camera Calibration - which Profile to use?

    This is a spin out of another thread in the forum - How do I avoid magenta discolouring?.
    I am using a Lr 5.7.1 on OS X Mavericks (10.9.5) and photos from 3 cameras - Nikon D600, Nikon D40, and Canon 450D - they all exhibit a very similar behaviour with RAW files described below, but it much more noticeable with the Nikons and very noticeable with the D600. I have been using Lr since version 3 (I think but I might have started with version 2, I cannot remember).
    By default I have always imported my RAW files leaving the profile under Camera Calibrations as Adobe Standard. I have been moderately unhappy with the results I was seeing in Lr, not with all the images but with quite a few of them; in a nutshell they don't as I envision them and they don't look the way they look in camera. With "the way the look in camera" I mean inspecting the histograms and clipping warnings.
    I am fully ware that Lr does not read the picture control settings of any camera, my Nikons have always being set to Standard.
    Below are 2 screenshots from a photo taken with the D600.
    1) Histogram with Adobe Standard profile
    2) After and before view, left "Adobe Standard" right "Camera Standard"
    There are 2 different images, the histogram is changed, the greens are render differently. I also know which one I'll pick for further work, the right image, the one with Camera Standard as the profile.
    Back to the question for this post: Camera Calibration, which Profile to use? (and why?)

    ssprengel wrote:
    Which profile to use is a matter of personal taste, so why does it matter what other people use?
    I am not sure I would agree with this statement without making some important qualifications.
    Camera profiles can be used for creative purposes, no disagreement there. However, I don't think this is the sole purpose of camera calibration and camera profile, isn't it? Jeff Schewe, who sometimes contributes to this forum, wrote in The Digital Negative "The profiles are designed to calibrate a particular camera model's particular colour rendering intent [...]. It's entirely possible that your particular camera might be a bit different from the one they profiled, so you might be able to make a customer profile for your camera that would produce a more accurate rending than what comes with Lightroom and Camera Raw"; the quote is taken from his section on Lightroom Camera Calibration and leads to conclude that the purpose of camera profiles is also to reproduce the colour rendering intent of camera.
    My point on the original post is that it seems that Camera Standard, with both my Nikons set to "Standard" picture controls, seems to better reproduce the colour rendering intent of both cameras, specially if greens are involved. All I am looking for is advice regarding best practice. This is absolutely non trivial from my point of view, best practice is not a matter of personal taste as I am sure you know. Insisting that default settings are best practice, I am not saying you are saying this, is not helpful.
    ssprengel wrote:
    As to your question about making Camera Standard the default profile, you do it the same as customizing any other LR default:  by selecting an unedited photo, setting Camera Standard as its profile, then on the keyboard use Alt - Set Default…  (the button was Reset before pressing Alt) then confirm that you want to update the LR defaults to the current settings.
    This is correct.
    ssprengel wrote:
    I am not sure how to find photos with a particular camera profile but perhaps one of the filters in Library can do that, or a smart collection query.  I don’t have LR in front of me right now to try things, myself.
    I don't think this possible. I cannot find a way to do it with smart collections or the filter library. I'll keep experimenting.

  • G5 presents QT as 256 colours (colors) - which prefs to trash?

    My G5 dual processor tower has been playing Quicktime movie clips perfectly until a day or so ago.
    I think the problem was downloading webcam applications to start using a webcam again. I downloaded Macam in the end and installed
    it and its component in library/quicktime.
    Anyway, now the G5 plays a QT clip off a recorded cd as if in 256 colours or worse. (Every face looks like a contour-map). Going to the A/V controls in the Window menu of Quicktime and tweaking the brightness slider a tiny bit to the right resolves it, but that setting can't be saved so I would have to do that everytime I opened a QT movie). Using the internet to look at QT streaming eg NASA TV everything is fine.
    My Quicktime version is 7.6.4  I am running OS 10.4.11.  On my G4 macbook with the same settings the QT movies play perfectly so it is not the CD.
    I have trashed the /library/preferences/com.apple.windowserver.plist  but no change. I zapped the PRAM.
    Any suggestions of more preferences to trash?

    In answer/further answer to the previous 2 questions:
    It is quite evident that the monitors (LaCie CRTs) are displaying in thousands in that the image one can view is quite evidently degraded, more like it is composed out of sand paper rather than a smooth transition of pixels. You can see for yourself, at least with a CRT (not so evident with an LCD display) simply by going into the Displays preference in the System Preferences and changing your settings from Millions of Colours to Thousands, and it is even more obvious when you downshift to 256 colours. For interim correction of the problem each time after I reboot I need to remember to go into the Displays preference and switch to Thousands and then back to Millions where the settings remain correctly rendering until the next reboot when their apparent effect returns to Thousands even though the preference box shows "Millions" of Colours.
    The problem is definitely software related, not hardware, at least not the monitor hardware. It maybe a bad drive component or someting in the internal drive wire harness... (I now own a stack of dead or bad drives from various machines over time which, along with an extensive history of Apple confirmed hardware issues, has convinced me beyond a doubt that a lot of evils are hardware related.)
    I'm sure of my previous statement because I do occasionally boot from another partition on an external drive wherein I never have the problems I have been describing. That is there is something in the configuration of my current OSX partition on my internal G5 tower drive, either softare or its internal hardware, that is causing these Display preferences to repeatedly corrupt over time. In the past through trial and error I've been able to figure out which combination of preferences to purge and rebuild, but for the life of me this time I can seem to get rid of the problem.

  • GT72 - Dragon Gaming Centre "Instant Play" & Display Colour Calibration issue

    Hi guys,
    Very much enjoying my GT72, but I've noticed a strange error that I can't seem to find the solution to either on this forum or elsewhere.
    Basically the computer boots up to an incorrect colour calibration setting (really blue) which I have tried to set properly with the default windows "Calibrate Display Colour" tool. It seems to stick after doing that, but rebooting reverts it to the previous default.
    I've also noticed that when pressing Fn+F4 for the Instant Play, it seems to change color display settings; if it was on the default really blue setting it'd change to my calibration, and vice versa.
    I was wondering if anyone had any ideas on how to prevent Instant Play changing calibration settings and having my calibration stick between reboots?
    Thanks in advance!

    yeah.... with so much different angle and good quality, they are truly good photo shooting pieces!

  • Colors differ in PhotoShop and Windows Viewer

    Dear members
    I got a problem.. when I adjust/ photoshop a picture in PhotoShop cs3 I save it.
    Then when I open it in the Windows Viewer.. the colors are different from PhotoShop. Some are lighter other darker.
    When I send this to print. The colors of the Windows Viewer match the result. And the colors of PhotoShop doesn't.
    I've got my screen also calibrated.
    Does anyone know where the problem is?

    Dave,
    Really there was no offense taken. It's only that these problems are a bit more complicated than simply calibrating the monitor. Learning to understand these things takes time. For me it took many long mountain bike rides and hikes in the Santa Monica Mountains where I could clear my head enough for the light bulb of understanding to turn on.
    I might have reacted a but harshly too. Really, we're all here to learn and share information and hopefully not get too confused.
    Assie,
    "'Trust what you see in Ps and don't worry about Viewer as it's just an approximation'
    "I think this is with my system different. When i see a picture in viewer and i let it printed professionally. The colors on the printed picture are the same of the viewer.. and not the same with those in PS. "
    Good, your back in the thread. In order to help you we need to know a couple of things. What is your RGB working space? What monitor do you have and how has it been calibrated - gamma, white point, luminence, calibration device, etc?
    With the images you are having printed professionally, what is the data flow for the printing? What type of printer is being used and what is the lab's color management setup? Are you sending them tagged files and if so, what profile is being embedded?
    Really the best way to wade through all this is one baby step at a time. First make sure that your screen is calibrated properly (this means hardware colorimeter) and your ambient lighting is correct for the luminence of your screen. Prints need to be viewed under a standardized light source. Inkjets love the lighting from Solux (solux.net). If you are going to display prints under other types of light, then it's best to make custom profiles that factor in the light source as part of the profile.
    Once you have your monitor properly calibrated, you can be reasonbly sure that what you see in Ps is what is in your file. For any kind of output, you need to customize the data for the output device. Normally this is done with output profiles, and usually better results come from custom profiles. You have to know what's happening to your data at every step of the way to determine where things are going awry if you get prints that are not meeting your expectations, so tackle one thing at a time and don't move on to the next until your'e sure the last step has been done correctly or it will be difficult to pinpoint what to change.

  • LP2475 - best colour calibration settings for stock photography

    Hi - I have just purchased the LP2475 and am new at colour calibration.  The general colour seems very over saturated.
    I am mainly using the monitor it to do 2 main things :
    1) using lightroom / pshop and adjusting photos that will be available online for stock photography purchasing.
    2) using lightroom /pshop and adjusting panos to print via 2 out-of-house print companies.
    I understand that I have to buy a colour calibration device and I will make up custom printer profiles for the 2 different companies where I get my photos printed (one is a canvas & one is a photo printing company).
    However, the issue lies in what general calibration settings I should have in lightroom / pshop for my stock photos - because once sold, they will be printed on all various types of printers, and viewed through various types of monitors - most not calibrated.  So what are good general settings.     It seems very over saturated with colour, and I cannot actually seem to adjust the saturation in the button menu on the monitor as this setting is greyed out.
    Thanks
    Lucy

    I recently bought a Spyder2Pro, which was
    recommended
    by Scott Kelby, Editor of Photoshop User Magazine,
    and am very happy with it. The main difference
    between Spyder2Pro and Spyder2 are multiple
    monitor
    support and more choices for monitor gamma and
    tempereature settings. Since I use multiple
    monitors, I went for Spyder2Pro, although it was a
    bit more pricy (got it for $189 at JR.com). All
    my
    monitors were calibrated very quickly and I was
    amazed how much difference the tool made. If you
    have one monitor to calibrate, I think Spyder2
    would
    be fine (it was $89 at JR.com a few days ago).
    One hint with the multiple monitor thing is that on
    the Mac, all of these tools just end up generating an
    ICC profile that gets assigned to your monitor.
    What that means is that they all actually support
    multiple monitors, just not all automatically... for
    the ones that do not know how to select displays, you
    can just move the menu bar to whatever screen you
    wish to profile and the software should create a
    profile for that screen.
    I use the EyeOne and like it a lot. But any hardware
    calibrator is better than none.
    As a side note, I think using a color temperature of
    65k for the monitor and a gamma of 2.2 is really a
    good setting to use with any calibrator.
    Svendo,
    I fully support the comments in this post but still prefer the GM Eye 1. Dont try to do the job with your eye. 99 times out of 100 you will be way off the mark.

  • ICal month view some events shown only as ..., they show correctly in other views.

    iCal month view some events shown only as ..., they show correctly in other views.

    This is so utterly annoying- I never had this issue with previous versions of iCal, and I can't even run those versions on tiger now that I've upgraded. The tiger upgrade in general has disrupted my workflow much more than I thought it would-
    Because of the way I use iCal, not seeing the full even title in month mode makes iCal pretty much useless to me. I don't want to have to click between dozens of events that begin with "Renders of" to find which set of renderings are due on which days. Nor do I want to go through and rename all of my "Renders of Levels 1a-3c" etc to make the titles more useful. It should just WORK.
    Well, let me know if anyone finds a better way of making this work other than "resizing ad lib until things sorta show up"

    Under the Effects-Lumetri Looks-Desaturation choose a B and W effect. Then add the luma corrector from the Video effects-colour correction section. Adjust the brightness and contrast to get the effect you want.

    For general advice see Troubleshooting issues with iTunes for Windows updates.
    The steps in the second box are a guide to removing everything related to iTunes and then rebuilding it which is often a good starting point unless the symptoms indicate a more specific approach. Review the other boxes and the list of support documents further down the page in case one of them applies.
    Your library should be unaffected by these steps but there is backup and recovery advice elsewhere in the user tip.
    If you've already tried something like the above then try opening iTunes in safe mode (press and hold down CTRL+SHIFT as you start iTunes) then going to Edit > Preferences > Store and turning off Show iTunes in the Cloud Purchases. You may find that iTunes opens normally now.

  • Opens and plays correctly in the viewer, but of zero length in the browser.

    The song I sing to FC is "I can't get started with you." It probably is my fault because I don't come in the front door like the rest of you, with capture from a camera. I come from Still Life, exported to iMovie. Unfortunately, Still Life seems to label the .MOV as coming from an old version of iMovie, even though I am using iMovie HD 6.0.1. Final Cut Pro will not import my .MOV.
    I have contacted Granted Software about removing the erroneous designation. In the meantime I tried a workaround by exporting from iMovie HD 6.0.1 to Quick Time Pro 7.04. I got a .DV and Final Cut opened it. Unfortunately, it opened it in the viewer and I do not know how to get it to the Browser and the TimeLine, where I can add the great effect which I want. It did play in the viewer.
    I then tried going directly from Still Life to Quick Time Pro and again got a movie that Final Cut would open and which would play in the viewer. This time the sequence did seem to appear in the Browser, but, Item Properties Sequence 1, while showing correctly much data about the sequence, was blank when it came to size.
    My Final Cut Pro is an upgrade from Final Cut Express HD 3.0, so I opened the same movie in FCE. Same result. Looked good in the viewer, as my consolation prize.
    Given that few of you travel this path, I am not overly optimistic about chances for a solution. But I thought I would ask. Gentlemen? Ladies?

    I'm the grumpy guy around here. It just seems to me that everyone expects to install FC Studio and be Dede Allen overnight. Just rubs me the wrong way is all. There's a pretty steep learning curve with Studio, especially for someone who wanders in from left field (OH, wait, Rand-- right field) and I certainly expect someone to at least TRY before asking the most basic questions. I've been working with this program since version 1 and I'm still learning things about it.
    The dsr-11 is a little workhorse of a deck. It's a real basic unit-- no vu meters, timecode or user bit display etc. But for getting your DV material into and out of fcp it's just fine. I've had mine for over 5 years now and it's steady as a rock. I've never had ANY issue with it. TIP OF THE DAY: Don't get clumsy and knock the door off. And insert small tapes gently. It takes it's time with tape insertion, unlike an old 3/4 or beta sp deck where you can slam tapes in and out without a second thought.
    Yeah, the manuals are pithy, but you know, there is a lot of great stuff to be learned from them. One of the things I love about fcp is that there are multiple ways to do any one thing, depending really on your workflow and methodology, and basic approach to a computer system. you can find things in pulldown menus, by keystroke commands, in folders in the browser. Actually it's easy to teach your self to skim the manuals-- there always seems to be an intro page or pages that describe in excruciating detail a particular function. If you grasp that, or know already WHAT the function is, you can skim forward to the HOW.
    DO learn the keyboard as much as you can. Dragging clips around is a sloppy way to work, in my never very humble opinion.

  • Modal popup window refresh the parent (calling) window/view

    I have a modal popup window that is adding detail records.  When this window is closed via the Hide method in my controller I would like to refresh the parent (calling) window/view.
    What is the best way to do this?
    Regards,
    Diane

    Here's my process.....
    2-windows & 3 views
    Window 1 - Selection View and Detail View
    Window 2 - Add View (used as a modal popup window called by a button click on the detail view)
    Selection View has all the options for obtaining a list of data for the detail view.  The detail view has an Add button.  Component controller has the hide method and access to the other components that do the update/query methods. On the detail view the user can click Add and a popup modal window shows.  User enters data and clicks either the add or cancel button.  The Detail view needs to refresh to show the additional data that has been added by the modal window.  There are calcuated values in the detail view from a supply function.  This function is not running and the values are not changed.
    What should be put in the hide method that will cause the detail view to obtain new data and supply the calculated values?  If I was using the Add view as part of the same window as the detail/selection views I'd just put in a navigation link between the detail and add views and fire the plug.  I like the idea of the popup window so I'd like to get this to work.
    I put the wdContext.initialize() in the hide method - which yes - caused the detail view to run - however the context lost all the key values so I received a data not found.  I then tried to initialize those nodes that did not contain the key values but the detail view did not display new values.
    Thanks for any ideas.....Diane

  • Colour Calibration / White Point setting - Is Imac Display really professional quality

    I am trying to calibrate my imac 27" using i1 Display2 calibration software. I am trying to set a traget of 6500 using the software but it advises the current is only 5600 and suggests moving the RGB sliders to get this current white point up to my 6500 target. Unfortunatly i have no idea where i find these sliders on my imac. Can anyone advise how i change my current white point to get to the 6500 target?
    Also, on the brightness issue, does shades work to reduce my brightness or will it simply interfere with my colour calibration?
    Finally, i was going to use my iMac for professional photography. (Mainly on line but some print work required). Honestly, is the iMac display up to the job or should i consider changing
    Thanks

    Corbybhy, the glossy screen is the biggest and silliest myth out there. Really.
    I have been a professional art director & designer for over 26 years, and by the way, for many years my high end professional CRTS were made of glass (and glossy). Another myth is that the screens cannot be calibrated, and are too bright. Hogwash. I use Spyder3Pro and have had few problems, guessing your device will be the same. Actually, the monitors seem to stay consistant for a heck of a lot longer than the old high end CRTs did. In the old days, most professionals calibrated to 5000k, but these days 6500k is the standard.
    The amount of MISINFORMATION that is being spewed always amazes me. If you can keep your lighting consistant and somewhat dim, your life will be easier. Reflections are simply not a major issue, and are also overblown as a issue (by the way, my iMac sits next to a window, I just use shades to dim the ambient light).
    I work mostly in print, and produce mostly publications, advertising & marketing materials. I have ZERO issues with my screen matching my proofs. ZERO. I do a huge amount of imaging, retouching & post-processing... all from my 27" iMac.
