Been having problems getting adequate results with CornerFix, and now it's time to ask the experts here...
I'm getting extremely grainy results when I run M9 DNGs through CornerFix. While most of the magenta cast is gone, the edges are very grainy, and the de-vignetting is not smooth.
I've created various profiles over the past few weeks, but can't get one that works well. Given what I'm seeing, I think I must be doing something wrong...I doubt many people would consider the results I'm getting as acceptable, and yet I know many speak very highly of CornerFix.
I've attached an example from my most recent attempt, using the VC 15mm f/4.5 Super Wide Heliar:
Original DNG straight from M9:
After running CornerFix:
And, a crop from the middle-left side edge of the above photo:
What I'm seeing is a very light left edge to the post-CF photo, plus the grain I've mentioned. It's near impossible to see in the photos above, but the center of both the pre- and post-CF files is the normal beautiful M9 look; but the post-CF edges are more grainy than Tri-X.
I've created many different profiles: lens detection on/off, different f-stops, overexposing (as recommended by CF) and exposing as metered, subdued and non-direct light, etc. Still can't get anything that I would consider decent enough.
Is there another way to make profiles, or anybody have lessons learned on making good profiles? Anybody have a profile for a VC 15mm they are "proud" of and willing to share? I know the benefit of CF is that the profile is unique to the lens, but I'm willing to try anything at this point.
I love the look, size and perspective of the VC 15mm lens (except the magenta cast), but am starting to think I should switch it out for the ZM 18mm. Not much point in have the 15mm if I can't get files out of it that I'd like to work on. Again, I'm pretty sure I'm the one doing something wrong, as many people have posted great photos from the 15mm using CornerFix.
Thanks for your help.
