Ideally the user would input the number of stops that the center should be darkened, and then the tool would scale that using a cosine function out to the edge.

Quote from: svedosh on December 03, 2014, 01:42:32 pmI confess that you lost me with linear gamma. Ok. here's the root problem. I'm still shooting on film with my beloved Master Technika, and the work flow passes through an Imacon and a desk top before heading to the client. Subjects are building interiors and exteriors (unless I'm shooting for my own pleasure), so uniform lighting is important. I respect the view of art photographers who like darkened corners; I can't live with it. I dropped the old Schneider 3c center filter for the 47XL lens, and they don't make any more. None on ebay or any of the usual haunts. So I'm trying to recreate it digitally. I can't get a 3c filter (2 stops at center image) but I can get a 3b (1.5 stops). So what's the pro consensus as to the least evil? Shoot with the wrong filter or correct with the wrong function? Or is the linear gamma solution an option?
