There is so much to see and read on here, that we are all guilty of skim reading! LOL!

You can create a blur type vignette too, so you were not wrong at all! And you did get my point that I preferred subtle vignetting. LOL! With subtle vignetting you don't so much see the vignetting as you see the center more clearly because there is a little more contrast. If you go back and look at Number 2, you may notice that the area around the flower appears lighter - although it is not. It's the outside edges that are darker. :-)
