so, say i have an 1200x1200 image. i crop this to 400x400. then i apply a vignette to the image. (at least how i'm doing it), you can't see the f'n vignette, because it applies it to the original image size. what am i doing wrong? i know i could increase the size of the vignette, but maybe i want it to be really thick (really black?) at the corners of my crop? i can't figure out what to do differently other than to export the crop & vignette it again.
