I have some older slides taken with a lens that produced significant vignetting (edge darkening) on the sides of the image. It is a gradual darkening equal to about -1.5/2.0 f-stop on the outer third of each side of the frame. Almost unnoticable on a cloudy day, it is most visible against a clear blue sky.
Before I try to upload these, does anyone know how to correct this problem in a photo editing program? I use PS Elements II. This is an old optical problem, and it seems someone coulda/shoulda come up with a digital fix for it by now.
My efforts at fixing this so far have not given me the results I want, as I usually end up with some stepping of the blue sky as a result of my correction.
Thanx!
