We must be on to something! I used Document->Convert Format/ICC profile and found that it is indeed RGB-32: After conversion to RGB-8, all detail is gone and the highlights are blown. The original files are 3 exposure-bracketed JPGs. The darkest has all the details in the clouds that I wish to preserve. Do you have a suggestion how to use the HDR merge function without this loss? As a test, I imported 1 picture (the darkest one) in HDR merge, applied a bit of local contrast, converted from RGB-32 to RGB-8 and again saw some loss of detail.

Thanks for the quick reply! Here are the settings: I tried fiddling with Resample, ICC profile (just 2 or 3 options) and Embed ICC profile - but no luck. All outputs look identical. Clarification of my original comment: when taking a screenshot, both the document and export look identical with the blown-out highlights.

Hi all, I'm new to the forum and have been using AP enthusiastically for a few years. I love the HDR and tone mapping functions, but discovered an issue when exporting the document. Colour rendering clearly is not equal in the document and the exported file. I have read several issues that address something similar, but was unable to find how those issues relate to this one and what I should do. This screen pic shows the problem in the highlights: Interestingly, when I take a screenshot, the document and export are identical. I use: MacBook Pro 13" 2017 sRGB IEC 61966-2.1 colour profile in-camera (JPG, not RAW) and in the export settings I am a nitwit on colour profiles, but it seems clear that my laptop is interpreting the document differently from the JPG+screenshot and that it has nothing to do with the screen or calibration. What can I try to make these images match?
