I've been noticing issues lately from time to time with certain images from my P65+ being much noisier than I would expect them to be, with even the noise suppression being unable to help.
Now, I've been REALLY busy shooting, more than a bit sleep deprived and a little scattered lately so it took me longer than I care to admit to figure the problem out.
I finally noticed that the noise was occurring only on the edges of images, in particularly when I was applying liberal movements to wide lenses. As it turns out, the noise was introduced when the LCC correction (with Falloff Correction applied) attempted to adjust for vignetting. Sometimes at full strength, it's trying to compensate for up to a 2 stop loss in light and the information just isn't there in the files.
So yesterday, I just dropped the Light Falloff correction to 25%, pumped more light into the right side of the frame, and all was good again.
It makes me think that (as much as I hate putting anything in front of my lens that I should go back to using center filters on the wide lenses.
I also had one more idea to resolve these instances.... shoot a middle exposure, shoot a +2 exposure and drop that on top of the middle using the LCC exposure (with NO Falloff Correction) as a mask in Photoshop. I'm gonna have to play with that now.... but first COFFEE.
I'll cross post this to LuLA, as I think it's pretty pertinent.
