P: Anamorphic Lens Support (De-squeeze)

I think having Camera Raw support is ok. I still think it would be best to have LIGHTROOM CLASSIC have the desqueeze function built in (without lens distortion corrrection). Just a simple, type in your squeeze ratio, and you get the final image to work on.

I already have builit actions to help 'batch' de-squeeze images in Photoshop. I think what would benefit a lot of us is having to go to Photoshop/Camera Raw and then back to Lightroom. Adding this to CR will not save me a step and the huge pain that it is to manage orginial images and de-squeezed images. 

So for me I'd say if we can prioritize a de-squeeze function in LR Classic let's make it happen. For camera raw support, we're already in photoshop. Those are my two cents. 

 Rikk,

4 pictures taken anamorphic. The .NEF was taken with my Nikon Zf using a Viltrox 28mm f4.5 autofocus pancake lens with a 17mm thread Freewell 1.33x anamorphic adapter attached to it with a custom mount.

The 3 .ARW files were taken with my Sony a6500 using a Sirui Nightwalker 35mm f1.2 manual focus lens with a Sirui 1.25x anamorphic adapter threaded on. One of those was obviously taken vertically.

I want to be able to enter a ratio. I have no need for lens profiles as most of my lenses are either modified or manual focus with no interface and therefore no profiles to be had.

I would like to be able to just enter a squeeze ration and specify horizontal or vertical for the desqueeze.

Bonus points if you can do a locked or unlocked image size ratio and if locked, specify what color bars you want on the top and bottom or left and right sides depending on horizontal or vertical.

I'm currently working on a custom lens (modified from a helios 44-2) that will have a 1.72 anamorphic ratio, hence the want for the ability to just enter a squeeze ratio value and not rely on common ones only or on lens profiles.

Thank you

To me it's crucial that de-squeeze is a seperate thing from profiled lens distortion and the existing Transform controls:

• I don't expect or need Adobe (or anyone) to profile every anamorphic lens that gets released.
• Usually we choose anamorphic because we like the character, e.g. vignetting, distortion.
• But hey, if you want to profile an anamorphic lens, great! Just let the de-squeeze happen without the rest of the distortion removal.
• De-squeeze should be seperate from Transform, so that we can still crop/rotate. straighten etc. with the image handled properly. Premiere and After Effects do this correctly with non-square pixel aspect ratios.
• De-squeeze should automatically change the aspect ratio of the photo, so that no cropping or borders are introduced.

@Dustin Stockel did you create profiles yourself for de-squeezing? Using Adobe Lens Profile Creator? What you showed there looks great, but I am unable to run Adobe Lens Profile Creator.app on my brand-new Mac, which seems like a problem. But it looks like you were able to create a profile that de-squeezes without any other correction?

For myself, just a simple desqueeze would be sufficient for my needs. That is what I do in video, and lens distortion correction is a different action.

Are we wanting lens profiles or just desqueeze support?  While I would love to have the additional canvas created for desqueezing, at least we can easily make profiles to desqueeze ourselves.

Agreed.  While I do plan on fully profiling the Catos and Remus I have, most times I just want to desqueeze, so that's how I have it setup.

I agree with this sentiment. I a simple de-squeeze function would be stellar. If it will speed up the process, I'd say forget about 'lens correction' aspect of it. Just a simple de-squeeze that can handle different ratios is what's needed. Hope this becomes a reality soon!
