P: Anamorphic Lens Support (De-squeeze)

Thansk to ChatGPT I now have an app (automator) on my mac that I can just drop a folder on... and it desqueezes all the dng's in it. And it skips the ones it has already done 🙂
So the workflow is very simple:

1. Import via Lightroom and convert raw to DNG
2. Drag my Anamorphic 1-33 folder on the app icon on my desktop
3. Refresh the folder in the lightroom catalog

Adobe lens profiler doesnt work anymore on newer MacOS. Dustin, are these profiles only the de-squeeze? Would you be so kind to share them?

Two anamorphic NEF raw files shot on a Nikon Z8, both using the Blazar Mantis 75mm T2.0 lens (1.33x anamorphic squeeze factor) :

I'm eager to get native anamorphic desqueeze support built into the Camera Raw engine, so that we might use it directly inside of Lightroom Classic!

Currently unfortunately not, but it would be ideal to have sliders at 1.33, 1.5, 2.0...

Could this be done in lens correction? 

thanks for this tip. best way for me. hoping that one day, Adobe will finally make this development to allow us to desqueeze more easily inside Lr

Many thanks for putting this subject forward!

I've been pushing back my editing on some anamorphic photography tests just because of how much of a pain it is to go from Lightroom Classic to Photoshop for the desqueeze and have a proper overview.

Sample infos:
• Camera body: Canon EOS R
• Lens: SIRUI Saturn 75 mm T2.9
• Ratio: x1.6

It felt important to include both horizontal and vertical samples, anamorphic vertical does have it's own character for photography and the desqueeze feature should cover it too.

I've also tested some anamorphic lenses that didn't keep a constant ratio when changing focus, in close ups especially (I don't have any sample for that though), so the lens profile solution wouldn't help with those cases, same thing for many moded vintage cinema lenses and other adapters, it's just wild territory.

I think a ratio slider going from -5 to x5 (precise enough for 1.33 / 1.62 ratios etc) would already cover all cases even the most extremes ones with adapters mounted on already anamorphic lenses, in both vertical and horizontal orientations.

Cheers,
Romain

Yeah, I saw someone mention custom lens profiles but couldn't figure out how to make a desqueeze profile from scratch. A step by step YouTube tutorial  or something like would be helpful if anyone was inclined to do that.

Hi @Dustin Stockel, like @Stu Maschwitz I too am really interested in your solution. I didn't see any info on how you were able to achieve these desqueeze options in your custom profile. Any chance you can elaborate on your process and/or share files as a starting point?
