The operation of the Photoshop color management

Hey guys!

I spent some time, research and try to understand the inner workings of the Photoshop color management and met much information unclear and contradictory, especially in what concerns the test format. I think I thought that some of them out, but (for ease of my sleep) I thought to ask direct questions, just to be sure. I guess it's more of a curiosity thing.

I'm on a Mac OS X 10.8, Photoshop CS6, monitor calibrated from the standard range, working in sRGB for the web.

(1) what I have gathered, to get a specific color as possible on my screen, all I have to do is the workspace sRGB or have images with embeded sRGB tag and including my calibrated monitor profile ICC loaded in OS X. In this way, all the images and colors in Photoshop will respect sRGB and my calibration profile will ensure that my monitor is in fact the correct sRGB color display (for as long as it's still capability). Fix?

(2) I have met many 'practical advice' where people mention using the format of test > Monitor RGB as a way to monitor the colors for the web and then I saw people saying that's not true. As I understand it, the function of monitor RGB strips the tag embeded and does not take into account the workspace of the image, instead showing you the RGB values in the 'native' of the screen color space, which in my case would be sRGB-ish. Photoshop color management, but not the profile of calibration of displayaround a bit. Fix?

(3) when the viewing a tag image sRGB, activating / disabling the test format: RGB Monitor on and outside has absolutely no effect. Am I right to assume that this is because the sRGB tag is getting 'off', but since the monitor is standard gamut, the native color space is always sRGB?

What I find weird is when I change the display profile in OS X to my only calibrated for, for example, a generic RGB, activating / disabling the test format: Monitor RGB effect - changes in brightness of picture visibly. If my above hypothesis was correct, it shouldn't happen, right? Where my confusion.

Thank you!

Many people overcomplicate it. It's actually very simple.

1 Photoshop converts on the fly from the document on the monitor profile profile. As long as the monitor profile is an accurate description of the screen, it shows correctly regardless of the original document profile. That's the whole point of the color management, translation of one color space to another aspect/goal of maintaining.

There is no particular reason to work in sRGB just because your monitor is (or close). However, you will not see directly the colors in the file that are outside of the monitor range.

2. waterproofing to Monitor RGB is a quick test to see how the image appears without any color at all management. I guess it could be useful in some cases, when you need consistency to accuracy. Other than that, it is completely useless, that it shows what it looks like on your system. And anyway, there is no reason today not to use fully color managed browsers.

3. Waterproofing is an extra turn to the conversion mentioned above. The point is to limit the range to test the profile, so that you can see this cutting will do to the image. It will documents profile > profile proof > monitor profile. If the profile of evidence has a range equal to or greater than the monitor profile, you will see no difference.

Important point to keep in mind: If the profile source and destination are the same, no conversion happens and color management is by definition disabled or disabled.

The first part of the string of audit, document evidence, may be a "convert" or "assignment". Convert maintains appearance, while assign run numbers, but changes its appearance. It's the checkbox 'Keep the numbers' in the proof Setup dialog box.

  • What's up with the bridge color management?

    After obtaining a range wide screen (Eizo S2243W), it was a pleasure to be able to see the Adobe RGB colors that I knew were in the file, but previously could not be displayed. Although the Windows desktop and interface elements user sounds loud, I got used to that.

    ID, PS, AI, everything works perfectly. But I discovered that the bridge does not follow suit. The funny is that it shows the mute, standard version for 'gamut' - saturated not as one would expect with a range wide screen and non-functional color management (if this is the case). The only reasonable explanation for what I see is that the document profile is converted to sRGB. I can't reproduce otherwise.

    I'm no stranger to the color of help desk management, and according to my experience, the prime suspect in this case is still the monitor profile. So I've done several things to validate the profile. I recalibrated using the calibrator Eizo grouped with its EX1 (actually just a renamed Spyder3) sensor, and I recalibrated using color eyes Display Pro with another probe Spyder3. I also tried with Adobe RGB as the monitor profile just for troubleshooting.

    In all cases, I checked in the color settings PS that the profile has been actually used, and in any case, the effect of muting still shows in Bridge. Now, I am sure that PS/ID/HAVE rendering is indeed good. Suite color management is synchronized, using Adobe RGB as RGB working space.

    I have also purged caches of bridge in every way I can think and then reset the preferences of Bridge by ctrl-launch and control of the confirmation dialog box.

    The screenshots of the following two require a color managed browser and a range wide screen, since the difference is outside the sRGB gamut. The first used Adobe RGB as a monitor profile and a Adobe Integrated RGB, the second has the Eizo monitor profile assigned and integrated. They are similar, but the other should show exactly as I see it (click to view the display not set cache, the difference does not directly show in Firefox):

  • Photoshop color management

    Hi all

    I noticed a small problem (which is probably my fault).  My color for some reason settings are all extinct.

    When I open a document in my preview of the BONE, the colors are as it should.  When I opened the document in Photoshop, the colors are all off saturated and muted.  When I use 'Save for web', which gives me a preview colors come back and save under the name properly, as they looked in the operating system preview.

    What is happening here and how can I do Photoshop open images as it should with no discolouration.  In my color profile settings, the only one who comes close is if I change it to "monitor colors.

    Thanks again in advance!

    -Patrick

    Set your display profile (in operating system settings) so that it matches your actual display.

    Right now your display profile does not match your screen and Photoshop tries to compensate for the incorrect display.

  • I'm trying to print using my own profile and no color management.   I have found a lead to the Adobe Color Print Utility but reached a point where he declared that she would not work with future versions of the Mac operating system.   I have Mac OS 10,11,

    I have been printing PSD images with my own profiles and color management using an Epson R2880.

    I've now changed to a Mac with OO 10.11.3 and unable to replace the color management.   I found a lead on the Adobe Color printer utility but failed and got a message saying that the utility has only worked with an earlier version of the OS 10.   Is there a way to turn this problem?

    GHK

    You don't want or need to use the old setting 'No Color Management'. Is no longer the right way to print with a custom printer profile, in the current versions of Photoshop and OS X.

    To use a custom profile to print, use the attached picture settings:

    • In the print dialog box, set the Photoshop color management menu manages colors.
    • Select your profile to the printer in the printer profile menu.
    • In the settings of printer driver Epson (under Printer Setup button) make sure that the Epson printer driver is set to the color - off management.

    I don't know why Adobe Color Printer Utility works in 10.11.3, because I can throw on OS X 10.10 and 10.11. But in the end, it doesn't matter, because you don't want to use it for this purpose Adobe Color Printer Utility is only to print a profiling target, no images. And it won't let you print using your custom printer profile, because the whole point of the utility is to print with no discoloration whatsoever.

  • Photoshop - Second monitor color management

    When I use Photoshop on my laptop (windows) on the image of the screen of the laptop and its colors are just about perfect.

    252360b4a67f7cb3ff19aa003e2da3ed.png

    However, when I drag the window to my second monitor Photoshop knows how to manage color at all and so my white and grey look completely yellow!

    eafe5fd9d07af5c4e09242d1eb653333.png


    It's very start especially when you try to design images for printing and so I was wondering if there is a way to disable the Photoshop color management and have it use the OS and default colors of monitor management games or I should say people change in preferences, I tampered with and changed all the settings and it seems to be able to adjust the color saturation and brightness but nothing gets rid of this yellowish harmonic and makes my whites white!

    Thanks for any help.

    You use Windows 7 or higher? You must run the utility of color grading on each monitor that you want to use.

  • Color management policies

    If color management policies are disabled in the control panel of the Photoshop color settings dialogue that happens when a file is pasted into a document that has a different workspace? Is the pasted file is converted in the workspace or are the numbers assigned to the workspace?

    EG: Working space is Adobe RGB 1998, the file being stuck in this document contains an Adobe sRGB space. The color numbers in the pasted document will convert to Adobe RGB 1998 or they will be affected?

    Thank you

    Citing the Description area of the Photoshop color management settings to the 'Off' RGB policy:

    "When you import the colors in a document, the numerical values of the colors are priorities on the appearance of the color."

    An assignment will take place.  Using your example, I checked by pasting a picture of sRGB rainbow gradient in Adobe RGB document with RGB strategy set to Off.  The rainbow gradient has changed to look the same, we would see if they had taken the original document of sRGB and reassigned it the Adobe RGB profile.

  • Cannot access the options of color management for HP 6700 Mac OS 10.8.5 (Mountain Lion)

    Hello.

    I have the HP Officejet 6700 Premium e-all-in-one, and I can't find any way to access the color management options.

    The printer is attached (Wi - Fi) to my iMac Mac OS 10.8.5 (Mountain Lion).

    I want to correct a magenta cast for the photos I printed.  I had the problem of magenta-cast in Lightroom and use Preview to print the photos, so now I want to work with color profiles in Photoshop Elements.

    Photoshop Elements is recommended I have 'disable color management in the printer Preferences dialog box.

    However, I am not able to find for the 6700 color management preferences in settings under Mountain Lion:

    Not sub (Apple) > System Preferences > print & Scan.

    Not sub (HP utility) > Open Embedded Web Server.

    Not sub (HP utility) > the printer settings.

    Non-print preview dialog.

    I can't find any clear directions in the online help (HP or elsewhere) that I've read so far.

    Any suggestions would be most appreciated.

    Hello

    Thanks for the reply and the screen shot.

    The first thing I want to do you is to reset the printing system.
    OS X Mavericks: reset the printing system

    Then add the printer, however when it by adding not just click on the name of printers, click Add printer or a scanner. Make sure that the 'use' is set to the printer and not Airprint.
    If it is displayed as Airprint, you will be missing feautres compared to the actualy printers driver.

    After that, I'll provide you know several documents that you may find useful to perform this task.

  • HP B8550, how to disable color management in the driver? MOS SNOW LEOPARD

    I would like to turn off the color on the printers driver management.  The challenge I'm having

    is my pictures on my computer do not match those of the printer.

    Hi bpj1242, actually you can simply disable the printer color management. What you need is an application that allows to manage the colors, such as Photoshop. In this application, you can then choose "Applacation manages colors." This will automatically disable the printer color management. In the print dialog box you will see under message options, the printer color management has been disabled.

  • Management of the print color settings

    I've never had no problem printing from Photoshop on my Macbook Air, until I think I've accidentally pressed some keys on my keyboard which was obviously shortcuts.

    Now, whenever I try to print - the first image attached appears, as it usually happens with normal printing pre box, where you can choose the paper size, layout, color etc etc.


    I visited the print settings dialog box and everything seemed normal.

    I also went in Edition > settings of colors... but it was a bit out of my League that I don't know anything about the print & color management settings.


    If this is useful - I've also attached a screenshot of my current color settings.


    Can someone help me pleaseee - it drives me crazy!


    Thanks in advance!

    Photoshop Print Settings.pngScreen Shot 2015-09-24 at 4.08.33 pm.png

    It is the normal print Photoshop dialog box. This must always come first. Access you the settings of the printer driver by clicking 'Print Settings '. It is also quite normal.

    Do not take into account the color settings dialog box, it is not relevant here.

    BTW, having the printer manage color is a somewhat safe setting, but you can usually get better results by letting Photoshop manage color and make the conversion to the desired printing profile. Then you will need to choose the right profile manually, and also make sure that the printer driver is set to the correct paper type. And the printer to support.

    In addition, the document profile is listed as "Display". This is the profile of Mac OS X will assign to the screenshots, but it is generally not a good idea to use the display as a document profile profile (both are different things and have different goals). Best to convert it to a standard such as sRGB profile if you intend to use the file to something else.

  • The duller colors of Camera Raw in Photoshop: why?

    Hello!

    I open my Canon 70 d with Camera Raw 8.4.1 RAW files. After this step, I open the file corrected in Photoshop CC. At this stage the colors have changed, everything is duller and less contrasted.

    See the image.

    Capture.jpg

    Color-managed raw camera: Adobe RGB, 16-bit.

    Photoshop color management: RGB: Adobe RGB (prepress Europe 3)

    In addition, no verification of color is active.

    How can I fix this problem?

    It is a problem with your display profile. The conversion of source profile to display the profile is not the same in these two cases, so a bad display profile can appear in this way.

    ACR converts from its internal workspace, linear ProPhoto. Adobe RGB is just export color space here, so not relevant. Photoshop OTOH converted Adobe RGB.

    Recalibrate and review the settings of your Stallion. Profiles of V4 and focused on the LUT have caused problems for some, so try and matrix-based v2 if you have these options. You can also test by substituting a known, good profile that would be for a standard display sRGB or Adobe RGB for a wide range.

    If you select "Photoshop manages color" the Epson R1900 with the commune 7.0 Updater installed on top of the 6. something driver automatically disables the printer color management.

    If for any reason any it is working properly, the R1900 user guide is available online. Page 28 and 29 of this guide shows how to turn off the Epson printer color management.

    Looks like a problem of color for me.

    Photoshop strives to show you accurate color rendition, by your images color profiles and color associated with your monitor profile.  Many / most of the other programs are not proper color management. It is the key.  You can interpret the color you like as the 'proper' color, when in fact it's one that's not going to.

    If your monitor profile describes accurately the characteristics of color of your screen, then it's the other programs that display the images in a supersaturated way, because they do not take into account the monitor's color profile.  Trust what you see from Photoshop.

    Chances are, given the images you posted, it could happen: your monitor is a model of the range of colors and Photoshop sees a profile associated (by OS) who tells him that, and so Photoshop color - managed accordingly: colors in the images marked with the sRGB IEC61966 - 2.1 profile are desaturated some , for an accurate display.  Other applications that ignore the color profile of the monitor will not transform the colors and will be over-saturating them.

    Another problem as possible: the monitor profile may not describe accurately the monitor.

    Color management is a bit too complex to try to teach the post by post on a forum.  I suggest that you are looking for information about it online.  Beware of people ' all mean ', because it is not a thing, you can just set and forget and do things.  You must wrap your mind on how it all works in order to make the right choices on your system.

    What do you see in the dialog box color management of your operating system?
