Recently I was playing around with some of my landscape pictures. I am struggling to understand that if in my picture colors, shadow, highlight everything looks perfect than how come it shows so much of clipping when I turn the clip indicator on? If the detail was lost wouldn’t it be apparent? When I turn the clip indicator off and see the areas where it was showing clipping I do not see any loss of details with my naked eyes. Also, trying to fix the clipping takes away almost all the nice looking contrast from the picture.
I have attached a screenshot of how the bad the clipping is in my edits. I have also attached the XMP and a RAW file so you can help me understand what am I doing wrong.
If you right click on the clipping icon you will see that it can be set to different threshold levels. I personally never use the clipping indicator when editing and just trust my eyes since photography is about the look. However, I use the raw clipping indicator to determine the best raw file from a bracketed exposure set of images.
In this one photo…assuming srgb for gamut checking then …just bumping it to 100 percent removes the warning which is mostly on the leaves and due to saturation I believe…if you then drop it you have to go down to a 90% threshold before any more significant changes show …or at least grossly so I think its just a calculation at the margins or the greens are really pushed …
I tried in ART just for comparison and like DT with the defaults some of the green leaves were out of gamut with the default processing and profile…
So I tested the Adobe DCP profile …standard one for your camera… there if you don’t use the look part of the profile you still have the gamut issue for sRGB
But enable the look and it is corrected at least for this image… so perhaps if you were to profile your camera with a colorchecker and get a new ICC profile for DT then you might be able to compensate for the gamut issues that might be attributable to the profile?? At least that is one interpretation…
I never tried color-checker thinking shooting RAW will give me full control on the white balancing my pic in post processing. But I will try out your suggestion and see how it goes.
Well and even before that (ie profiling the camera) the CC module can use the color chart in conjunction with the channel mixer to introduce a tweak to the standard input profile … You can use settings for neutral and some others that might be nice for taming your greens and improving color accuracy in your landscape shots. I think there is one that is biased towards correcting foliage if I recall without looking…
In all my viewers/editors those levels are set to 1 and 254 equivalent, because at 0 and 255 you don’t know whether they are clipped or not. I keep them turned off normally, preferring to view the histograms in order to assess the degree of over/under exposure.
In the case of this image it a gamut thing … The overexposure tool in DT can be set for gamut exposure or a single RGB channel …by default I think it’s set to full gamut
Hi @europlatus,
i tried to take a look at your xmp file, but I think it doesn’t contain your edit? When i open the xmp in an editor, i can see that only the modules rawprepare & demosiac are in the history.
if you still have the full edit, i would be happy if you could upload the full file again
I don’t worry gamut clipping, the transform to rendition gamut should take care of that. Luminance-wise, I don’t see any clipping in your capture, which would indeed lose detail.
Here’s my take, primarily concentrated on a tone curve to dig out some shadow detail (loggamma curve followed by a control-point curve that I shaped by-hand), then a crop that took out some of the left-hand stuff to put the sky reflection on the water in a place to lead the eye:
