Re: Issue : PWP clips highlights of linear DNG file

I asked Google Gemini about the handling of raw files by darktable. darktable uses the RawSpeed library to read raw files, including linear DNGs. RawSpeed is an open-source library originally developed by Klaus Post and now maintained as part of the darktable project. Here's how darktable potentiall...

Re: Issue : PWP clips highlights of linear DNG file

Could you enable user-control of highlight and gamma ? .... Been there done that.
Im not sure of what your answer means.

One more observation: Dark table, which is also built on RawLib, does not clip the highlights when processing the same DNG file.

Re: user interface : unexpected order of processing in batch with splitter

The point is not that a big deal now. The two breakpoints are on a warp transformation. I was confused by the first breakpoint occuring on the right branch, which I had not noticed since my attention was on the transformation dialog box. I thought there was some sort of corruption in the software as...

Re: user interface : unexpected order of processing in batch with splitter

Would it be possible to sort the transformations, such that when a choice of execution order exists, leftmost transformations would be processed first ?

Re: Issue : PWP clips highlights of linear DNG file

When Linear DNG is used, I would expect that no other editor is required since demosaicking is already performed. In this case, demosaicking is performed by Adobe Camera Raw. It would be nice if PWP could directly input DNG files without clipping the highlights. I asked Microsoft Copilot about libra...

user interface : unexpected order of processing in batch with splitter

See attached screenshot and workspace script Observation Branches can be executed right-to-left, as evidenced by the occurence of breakpoints. The first observed breakpoint occurs in the right branch. Expectation The breakpoint in the left branch is expected to occur before the breakpoint in the rig...

Re: Issue : PWP clips highlights of linear DNG file

Hello Johannes, I went back to the NEF file (not the dng-converted file). Blown highlights are detected after development. Exposure compensation plays a big role in this. As shot, it has blown highlights, as detected by Photolab 8: 2025-03-26 PL8 with blown highlights151047.jpg By reducing exposure ...
