P: Anamorphic Lens Support (De-squeeze)

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? 

Thanks for the insight regarding the processing engine. Good to know!

Regarding your comment:
"Maybe if we just spam post "Lightroom Classic" into this thread about 10k times it will get moved to where we want it."
No - learn how the forum works before going off half-cocked... 

Put me on payroll and I'll put in the time to learn how the forum works. No need to get snarky. We're just excited to hopefully see some sort of progress on this since the thread started back in 2013.

Respectfully,

Ivan

@Rikk Flohr: Photography here are some samples: https://www.dropbox.com/scl/fi/1li4iy7wxyffa787mwrln/Sony-Anamorphic.zip?rlkey=77etoa3re7pn4ebniawxvs6kj&dl=0

Ahh, good to know.

Thank you for the clarity Rikk.

I did not know the engine integration of Camera Raw in LRC.

Lightroom Desktop, Lightroom Classic, and Camera Raw use the Camera Raw processing engine.  In order to have this feature in any Lightroom Platform, it has to be in the Camera Raw engine - which is why it is moved here.

This thread was in Lightroom Classic.

Every thread opened there keeps getting moved into thread in Camera Raw.

I think the admins may dislike us or have something severely against people who use LRC.

It's actually getting pretty damn aggravating.

My original post and thread was in LRC and it got moved to this one.

Maybe if we just spam post "Lightroom Classic" into this thread about 10k times it will get moved to where we want it.

Didn't realize that this thread was for Camera Raw. Just started a thread in the Light Room Classic. Here's the link. Wouldn't it be nice to browse through our anamorphic images already de-squeezed without having to go to Photoshop/Camera Raw? If anyone gets a chance, please hop on over there and upvote so we can get traction on this missing crucial feature.

Cheers,

Ivan
