    Re: Adobe RGB vs. sRGB

    I think the reason some people are not seeing a difference between the sRGB image(s) and the aRGB image(s) is because some browsers/image viewers respect color-space while others do not. It's entirely possible a particular phone, tablet, browser, etc. is displaying aRGB images in an sRGB color-space.

    @hark :: Not that you're asking for my advice on your workflow but I feel your pain regarding clipping and such when working with a pure sRGB workflow. That's one of the reasons I switched to an aRGB workflow as well. In short, I import and do all my raw processing in aRGB. As a final step I'll convert the image to sRGB, do a "Save As" and use that .jpg for posting online. If, and when, I find I have clipping issues once an image is converted to the sRGB color-space, I deal with it then, on a case-by-case basis. It's annoying to some degree, having to do that, but I'd rather do that than sacrifice the wider overall gamut that aRGB provides. Remember... You can always down-sample but once down-sampled, there's no going back... I decided on this workflow after experimenting with even wider gamuts, such as ProPhoto, and finally decided that working with aRGB is a good, middle of the road sort of path.

    My thoughts on shooting .jpg are simpler: shoot and process in sRGB. If I'm shooting .jpg's the whole reason is to AVOID post-processing altogether. If I'm going to process a shot, I'm going to process a raw file. I'll let my camera "post-process" my .jpg's.

    Just my two-cents.

    Thanks for the info, Paul. After updating Camera RAW on my laptop, that's when I began noticing a much larger issue with clipping. This has been my only workable solution. Moving forward, I think I will simply switch to sRGB at the very end. I haven't had any issues when printing sRGB but also haven't scrutinized the difference when printing.

    My normal browser is Chrome. After just viewing this thread via Firefox, the red tree has a very subtle difference in color and brightness...but not by much.

    Here is the screen shot from my phone (via Tapatalk). It lists the bytes. I swear when I looked at it last night, the bytes both were listed in the 1xxx range, not the hundreds. Might have been because I was tired and heading to bed. Yeah, let's just go with that!

    Re: Adobe RGB vs. sRGB

    @Horoscope Fish , I'm trying to wrap up my understanding of color space...
    Would this be true.... We may be experiencing clipping in our processing. Since aRGB has a wider range of colors, that is, it can display more extreme reds, blues, etc., there is less clipping. Have I got that? And moving ahead, not everyone's equipment/software handles the aRGB the same. Some systems might just ignore the extremes, leaving some 'blah'. And other systems might convert everything to sRGB so some people might see little or no difference between the two? Am I on the right track?
    I must have a really good camera.

    Well, yes and no... aRGB is a broader color-space than sRGB. Period.

    However, there is much overlap between the two color-spaces... aRGB overlaps with sRGB everywhere except in the Blue and Green channels:
    ......
    Adobe RGB vs. sRGB-srgb-vs-argb.jpg
    .....
    That being the case I would say, "yes"; aRGB images will be better able to capture color in those areas not covered by the sRGB color-space but, since the overlap is effectively 100% in the Reds, i'd say, "no" to that part of your question. I may be splitting hairs a wee bit but I'm trying to be fair and accurate. What matters to me is that aRGB is the wider color space and that's why I've chosen to use it. It's bigger, it's arguably "better" than sRGB so why NOT use it, right? The answer to that is, because every so often you'll clip a color channel when converting a shot from the wider aRGB gamut to the smaller sRGB gamut. You then have to either go back and correct it in the aRGB color-space (so it doesn't clip when converted to sRGB) or learn to just let it go and get on with life. Sometimes (most of the time, in my experience) the clipping is so minimal I just let it go.

    You're on the right track. When a photo is assigned a particular color-space it has been "tagged". This means the photo itself contains a bit of information about it's color space that image viewing software can read and understand. Some (and these days I think most) Internet browsers see that tag and will display images accordingly. Safari is color-managed, Firefox is color-managed and I don't know about Chrome. For a long time Chrome was not color-managed, but that may have changed. Individual applications on your phone, tablet, etc. may or may not be color-managed. I would think this day in age they would be but it's not a given and it can account for why the same photo will look different on different devices.

    Re: Adobe RGB vs. sRGB

    On my PC at work (big AOC monitor), the bottom photo has less vibrance. It's very evident.

    On my Galaxy Note 8, there is no difference at all.

    Here's a Flickr album of only two photos, processed the same way you did it. One in AdobeRGB, the other sRGB. On my same monitor here at work, they look the same. I'm wondering if Flickr changed something.

    I'm actually surprised with that. The bottom one *should* be the more vibrant of the two if there is any difference in color. Hmm....

    Adobe RGB vs. sRGB
    Here is another comparison. The first image was done as Adobe RGB. The second is sRGB. I have an entire folder of car show photos that will require converting. I did batch processing one time for resizing but haven't ever done it to change my color profile. 126 images is a lot, and I don't want to mess this up.
