Lensfun Ca Correction


#1

Hello everyone,

i have just tried to develop a raw i’ve shot with a Fujifilm X-M1 (xtrans) with an M42 28mm Petri lens. Both are supported by lensfun (lens for distortion and ca).

Distortion is correctly handled, ca isn’t. I post a screenshot.

Unfortunatly in the exif data i have 58mm focal lenght, it’s a pain to change the value every time i change lens, and choosing a longer lens is better for the auto iso implementation of that camera.

I think it could be a nice file also for checking this, since xtrans has no auto ca correction and this lens has both strongs distorsion and incredible ca :wink: : https://github.com/Beep6581/RawTherapee/pull/4515 .

On wetransfer a link to the file: https://we.tl/43Vqq0IwKY

Thank you in advance.!

–original follows:

As far as I know, lensfun CA support is currently not implemented:

@agriggio would know more.
