I tried the same process in 2 non Adobe HDR programs ( Photomatix 6.3 and EasyHDR 3) that save in OpenEXR.
The highlights did not clip in the underexposed shot. Despite this, when I made the OpenEXR file and converted to 16 bit, the highlights clipped. They were DNG files I made with the Adobe DNG converter from my Sony A1 RAW lossless files.
I used the same function for a different pair of 3 bracketed shots.
I have the latest version of Photoshop CC 2022. I took it to Exposure X6 and Exposure X7 ( not from Adobe) and had no color banding or other problems redistrubuting the tones and colors and doing other slightly elaborate edits. I then exported the layer as a 64圆4圆4 3D LUT. I left the bottom clipping numbers at 0 and 255 while moving the slider on the histogram. I saved the 16 bit file as PSD in Prophoto RGB, made a levels layer, and slided the highlights to the left and the shadows to the right. I took the OpenEXR file in Photoshop, changed to 16 bit mode, and selected exposure and gamma. In the past, I used Photoshop CC 2021 Merge to HDR Pro to blend 3 DNG files and save as 32 bit OpenEXR. better than Photoshop CC and Lightroom Classic CC without all the problems with conventional HDR program methods. The absense of clipping and color banding in Exposure X7 allowed me to adjust the tones, colors, etc. The highlight clipping and all the problems with it vanished. I blended the photos with Merge to HDR Pro, saved as 32 bit OpenEXR, made a 16 bit PSD file with Exposure and Gamma with the right numbers entered, adjusted the levels and gamma in new layers, and made a 64X64X64 3D LUT for use in Exposure X7 (a non Adobe program), and took the flat 16 bit TIFF file from Photoshop to Exposure X7 along with the LUT. I tried the same set of bracketed photos with Photoshop CC 2021. The rep made me install Photoshop CC 2021. I then did a screen share with a support rep from Adobe. No such issue existed in Photoshop CC 2021. So 6 output options but only with 2 real output generated.Previously, I posted about Photoshop CC 2022 clipping highlights without fail despite the underexposed shot in the bracket not having clipping when using Merge to HDR Pro. The Compatability options for Lightroom are the same in Lightroom and DNG converter: So,not a specific Lightroom issue it seems. I downloaded Adobe's DNG converter for a 'second opinion' but the same results there. I tried to generate a 4.1/7.1 DNG from my Nikon NEF's but that did not work, in all casess the result remained the same: Compability Ligthroom 1.0 With all testing i discovered some strange behaviour i could not find any information about. One of the problem images i shared in my dropbox folder: Dropbox - RM_20160311_161039.dng Can someone test it on his/her Windows 10 system and let me know? However, these DNG's are no problem for explorer. In Lightroom i tried to make DNG's with al lower 'versions' available (see list below) but only version 1 (CR 2.4) is generated. I almost never navigate to my folders with DNG files so i never noticed before but explorer is crashing on folders where DNG's reside which are made with compatibility with Lightroom 4.1 (CR 7.1).įirst i tought it had to do with my RAF files, turned into DNG's but i think it has to do with the compatiblitiy.
