This is a Color Test (for my own illumination) and I'm sure others will have some wisdom to share. In the past, the safe route was to work in a wider gamut color space to preserve color and avoid premature clipping (ProPhoto RGB, Adobe RGB, P3, etc), then convert my small JPG files to sRGB for emailing and web posts to be sure other saw essentially what I saw (limited to sRGB, of course). That was a good approach for images heading to an inkjet or to a press too because sRGB whacked a lot of colors that can be printed using CMYK inks (not to mention additional ink colors and spot colors). I have a good friend who is an experienced, color management professional and it's his opinion that converting to sRGB is no longer necessary (with a few limited exceptions here and there). Most browsers and email clients are color managed these days. I respect his judgement, but it's always nice to test and get some confirmation and feedback, which is what this post is all about. I created a composite image in AP v2.4.0 and used Apple's Display-P3 profile in this file. I purposely chose an image that has skin tones, some subtle shades, some bright colorful portions, then added some grayscale and fully saturated color patches for evaluation. I wanted any differences to be visible if they existed. ( I haven't viewed the results on this forum yet, as I am still creating the original post.) I'll attach the original AP file, along with 3 different exported JPG versions, all 2000px on the long side, at 85% JPG quality. 1. First, I exported the Display P3 original from AP and embedded the Display P3 profile in my first export. On my Retina display, that is the brightest JPG of the three, since my display IS a P3 display. So, the color patches retain their original saturation and brightness. 2. Next, I exported the Display P3 file from AP, but on export, I converted the file to sRGB 1966 and embedded that profile in the export. As expected, the saturated color patches are less saturated because they are now clipped to the smaller sRGB gamut. The rest of the image looks pretty much identical on my Retina display and also on an old Viewsonic sRGB gamut LCD display (about 15 years old). That is what I was expecting and hoping for. 3. The third JPG image export I did differently. First, I converted my original AP file from Display P3 to sRGB. Then, I exported to sRGB. The color patches look the same as in No. 2 above, which I expected. My daughter also looks the same overall. However, I was a bit surprised to see that the foliage in the background showed a tonal shift (slightly darker) compared the the sRGB exported from a Display P3 working space. This was the same result on my Retina and Viewsonic monitors. As mentioned, I haven't seen the result as posted on the forum yet, but I will after clicking the "Submit" button. By the way, I chose Apple's "Display-P3" profile for this test. Why? It uses a tone curve that looks identical (or at least very similar) to the tone curve in sRGB. This should minimize any tonal changes between sRGB and Display P3 (which is why I was a bit surprised to see the foliage in No.3 above different from No. 2 above). DCI-P3 (at least the version I have) is an ICC v2 profile and was supposedly designed with cinemas and theaters in mind, so they use a very low white luminance and a gamma of 2.6. For the work I do, I felt Display P3 made more sense. BTW, the Apple Display-P3 profile I have is an ICC v4 profile. So, there it is. I suspect some people will have some interesting feedback, so bring it on!! I'm about to click Submit, so I'll get a look at the post at the same time you do. Thanks. P3-sRGB Test.afphoto
