Hi, I'm using lensfunpy to correct my raw footage made with my Canon DSLRs (and MagicLantern). I export the geometry distortion as a UV map to un-distort the images, this is working well so far.
But I've got some issues when it comes to vignetting correction, it seems that apply_color_modification doesn't accept floating points data as input, I get either an error or a strange image as output.
I decided to try with 8 bits images, but I'm wondering if the output is gamma corrected.
Could you help me ?
