Vignette correction

The lens I took this photo with is a Canon FD 50mm f/1,8 adapted to my DSLM. The photo is a total mess, I just didn’t pay attention at this moment. I focused on the clock at an aperture of 1,8 and then I forgot to go back to 9.0 or 11.0 for the shot. It also appears that I messed with the exposure time, dialing it to 1/16000.

The photo now serves as a training subject for me for correcting a heavy vignette in RawTherapee. Not that I never corrected a vignette in RT. But this photo gives me a hard time. I’d love to see how you do it. Of course I also like to see corrections done with other software than RT.

In addition to the RAW in question I upload another similar one I took with an aperture of either 9 or 11 as a reference for the vignette correction I want to achieve.

my proposal: in addition to the standard vignette correction of RT, I darkened the center of the sky a little bit:

Thank you, I will take a look at your .pp3 file.

A quick attempt using Adobe’s lcp file, I will try to make something without it.

No lcp and slightly darker:

Every single development looks good. Play Raw is wonderful, one can learn so much.
