P: Enhance - Denoise or Super Resolution - should inherit edit history

[Antoine HLMN]

Hi,

It has been some time since I haven posted anything here. Mainly because I haven't been using LR a lot since I was disappointed by the updates or ... lack of them. That feeling remains. However, I must admit the most recent features of enhancement, Denoise and Super Resolution are much welcome. Certainly Denoise, as noise reduction used du s..ck compared to third party software.

Soooo, I would suggest to inherit the edits history when applying photo enhancement. This should be easily fasible starting from the raw file and copy pasting the edits.

Why?

Large amounts of history affect performance, bloat the catalog with what is in effect useless data.

The Enhanced DNG is new file! Also, whilst Denoise will append any existing edits to the new file, Adobe recommend that Denoise is carried out before edits are applied.

Why not make the same case for Virtual Copies, Copy/Paste/Sync?

Because LR is about being non destructive as much as possible. It means you can't edit or undo or edit parameters once Enhace has been ran. That's the whole point of DAM and  NLEs compared to open in PS, or any other plugin returning a Tiff file. Having the (raw) data at one side and the edits in LR database.

You don't necessarily know you're going to use Enhance while editing an image. See where noise reduction is burried under Basic, HSL, tone curve, ... tools.

Exactly, and that's how I'd suggest it to work: while editing a file, when Engance is prompted by the user, perform the Enhance on the unedited raw file and then apply the already performed edits. This way, you apply the Enhance on the linear image (raw) and kook it by copying the edits.

Other way to see it: imho, it makes no sense to have a .dng file with the edits already baked in. It goes against the spirit of the .dng file as a replacement for a raw file.

"Because LR is about being non destructive as much as possible."

But - as Ian points out - Denoise creates a new "RAW" file: so in terms of the original, it's completely non-destructive anyway.

You have fundamental misunderstaing of denoise works. Denoising ignores any existing edits during the denoising process. In short, the edits are applied to the denoised file, not before.

[Antoine HLMN]

It's true, it creates a new .dng, which contains the edits, and are not baked in. Opening that .dng in a non-Adobe software just opens the "raw" (unedited) file. Opening it in Photoshop, it opens Camera Raw in order to process the edis. So basically, it knows which edits to apply, and weather those are 'compressed' in a single, last action or containing all the edit history shouldn't change a thing. When processing the image, I hardly doubt it process all the history in order to finish with the last one. It also doensn't contain processed information, as it would blow file zises immensely. So displaying the edi'ts history shouldn't affect prformance and Ian's answer, with all due respect, might not be 100% corretct.

At Ian, sorry if I wasn't clear. I was talking about all the edit history (crop, masking, Exposure, Tone Curve). Of course, Enhancing an image creates a new image on which those edits must be applied. It's a given that and upscaling or "AI"-noise removeal cannot -or at least not that easlily- be undone.
