I came on to report a few stuttering issues on importing to a catalog from my CF card(which is what I normally use). They populate in chunks, which can be ok, but they don't until I scroll around to "force" it.
That's a problem!
I'm smiling as I read your last point about inverting the RG...I so far just tried the gradient once, and noticed it "zeros" out the area in the center, and thought "weird, why isn't the center getting the treatment"...Then I realized I guess it works the same as the grads....UNTIL I read your post!!!! I was hoping it did this!!! (I just hadn't played around with it enough, I guess). First chance I get I will check it out.
