Hi everyone!
The problem I'm having is the photos appear in slightly warmer colors than the original image.
So it's not just about exporting, but directly viewing the image.
The same problem happens when using Lightroom.
The images I am working with have color profile Adobe RGB (1998), my working space is sRGB, when I open the image I select: "keep embedded profile", when exporting I select "Embed color profile" and "Convert to sRGB" .
I state that I have already read the thousands of threads here on the forum, but I cannot solve the problem in any way.
I have tried all the solutions but I don't understand what the cause is, I would like to understand first if it is a "problem", or simply the image is improved.
I did the same test with a windows pc, and the colors are kept the same, even when converted to sRGB.
I leave here 2 screens where you can directly see the difference between the 2 images, where the original is colder, while the open and exported one is warmer. And other screens with working settings.
I suppose I could make a screen capture from Preview of the two outlines and provide a deltaE (difference) report, but it's tiny and somewhat insignificant on this end. I don't know why Preview is having this issue, but Apple hasn't been as thorough in dealing with color management issu
Also, please tell us what each of the screen shots shows us, what app (where the app title isn't shown) and what system. It's often MUCH harder for people who didn't create the image to see the problems or know what is right.
The app I use to view the original, exported jpg file is Preview (macOs).
I also tried with a browser (eg. Google Chrome) and the result is the same, even knowing that the browser does not manage the color profiles.
I have read about similar problems HERE: the difference is that in the other cases it happened on Windows and not on Macbook.
I tried to recalibrate the color profile of the screen, both color LCD and sRGB, but nothing changes (by recalibrating the white on D 6.500, the original white point is D 6.509).
Preview is color managed, and should display identically to Photoshop. If it doesn't, something in the color management chain isn't working as it should. When two color managed applications disagree, the prime suspect is always the monitor profile.
I can't see anything wrong with your settings or setup - except that you have Proof turned on in Photoshop. There's no need for that, so turn that off and check again. Sometimes proof tables are a bit off.
Another possibility is that color management is working, but one of the apps is using the wrong monitor profile. That can happen in a dual display setup, especially if one of them is an integrated display (e.g. MBP/iMac).
If you have Lightroom Classic, again, you can compare the image to Photoshop in the Develop module and again at 1:1. They should match exactly. If not, we need to look into possible GPU issues or display profile corruption.
With Mac preview, the image exported from Photoshop matches exactly what I see in Photoshop, what doesn't match is the original image displayed by Preview versus the same image displayed in Photoshop.
IF the original is in Adobe RGB (1998) and the exported image is in sRGB, and you're on a wide gamut display, you can expect a slight difference viewing the two; one has a smaller color gamut and the larger color gamut is visislbe on a wide gamut display.
I know that the 2 color profiles have a different range of colors (one wider and one smaller for the web), but I expect the whites to more or less match.
In fact, as I said in the previous threads, if I see the image in "Proof Colors"> sRGB, I see the colors faithful to the original image, displayed with Mac Preview.
My need here is to export a series of images for the web, all of which are native with Adobe RGB 1998 profile, and stay as faithful as possible to the colors of the original and the intention of the photographer.
I can drag and drop with the shift key one layer over to the other image. Of course, one MUST convert to maintain color appearance (not color numbers). They line up in perfect sync and as I toggle the layer on and off, I see no difference.
It could be an issue with the 'export' process or JPEG compression. We need more info about this and if indeed, if you bypass this 'Export' and simply convert, maybe resize and save as JPEG, if the issue disappears.
I had the opportunity to do several tests on another Macbook air, installed Photoshop latest version, with macOs older than mine.
I tried the various exports and the results are exactly the same as mine, so thanks to this I rule out a broken display profile.
For the original image I don't have too much exact information to answer, which I know are simple shots with Adobe RGB associated color profile in 8-bit raw camera, I don't think a particular job has been done, if not the classic steps.
Export 2. Open the original image in PS > Save for web with: JPEG, Maximum quality 100%, Include ICC Profile active, Convert to sRGB active. The result of this export matches to Export 1.
Export 3. Open the original image in PS > Save for web with: JPEG, Maximum quality 100%, Progressive active, Include ICC Profile active, Convert to sRGB active. This is the export I have been using since the beginning, and in this case the result is that the red is increased compared to the original image and Export 2.
Export 4. Open the original image in PS > Export as with: JPEG, High Quality (7), Convert to active sRGB, Include active ICC Profile. The result is exactly the same as in Export 3, as Export as JPEG, by default it makes the image Progressive.
So here the difference lies in the activation of Progressive JPEG, where if deactivated the colors of the image remain more faithful to the original, if activated the colors become warmer.
The strange thing is that if I view all the exports on a browser, or load them into a website, the colors are exactly the same, and they all correspond to the Export 3/4.
The other thing is that the original image I see in Photoshop corresponds exactly to the Export 3/4.
So even if I export according to the Export 2/3 mode, and then upload to the web, I will still have a different result than my saving.
maintaining the fidelity of the colors of the original image, but that it is as close as possible to what I will see in the browser, so as to already have while saving a more real preview of what I will see on the web.
I haven't used Progressive JPEG for more than a decade and I don't observe them in my daily life - may be because JPEGs are downloaded too quickly to show the progressive download process. I don't think you need to use it unless it's a requirement. Is your browser colour managed, by the way?
The color of my browser is managed on Default, even forcing the profile color to sRGB the results don't change (restarting the browser, of course).
Then I believe that if using the Export as function of Photoshop, automatically integrate the Progressive, I think it is a simple evolution and adaptation to the image on the various web devices (PC, smartphone, tablet, etc.)
@TheDigitalDog As I said above in previous threads, for the display I use the system default color profile Color LCD.
I tried to recalibrate it by bringing the white point to D 6,500 (the default white point was D 6,509).
I did the same thing by trying another display color profile sRGB IEC61966-2.1, tried exports and various activities but nothing changed, it remains exactly the same as for Color LCD.
Ok, if I understand, Export 1 (convert to profile then save JPEG ) and Export 2 match. This is what is expected and what I'm seeing too. Export 3 is the issue (bug?) and not how you should proceed. If this is the correct understanding, I think the next step, if even necessary is file a bug report and simply stop using Export 3.
@TheDigitalDog Exactly.
But what I see in Photoshop (starting from the original image itself), match with Export 3 (progressive jpeg), and not only, even with the various browsers (Chrome, Safari, Firefox), the only one that shows me the difference is Preview Mac. For this reason it is not clear to me who is right and who is not, and how to deal with export.
With Mac Preview, I see img_01 and img_02 with different colors, the first more faithful to the original image while the second more red. I can't explain why since the color profile is the same.
If I open these 2 images in Photoshop, however, I see them exactly the same, the correspondence of what I see in Photoshop (starting from the original image) matches with img_02 (progressive).
