Hi guys, thanks for the replies as always.
Good notes on the catchlights, cant understand how I can stare at a picture for 10mins during editing and still manage to miss these things. All three of these were taken from either full body or 3/4 body pics that were then blown up using Blowup3, which I just got yesterday morning. Must admit I'm quite impressed with it, and i was looking forward to going through some dusty RAWs of unusable pics due to cut limbs, posing, dog running in out of nowhere etc, and just making face shots with them, which is what you have here.
My slapstick painting on #1 is obviously very noticable though lol, however it wasnt her shoulder i was painting out, it was her hand that was held just slightly away from her chest. The shoulders are at a very square angle and I dont think her other shoulder was visible at all behind her neck, and if anything was seen, it was almost certainly blown out in the highlights. The right-angled shoulders were why I never used that pic before in the first place, and I didnt have the means to crop to her face without being left a pixelly mess.
(Lol Derrel, you brought out the paranoia in me there, I really really really hope that my days of painting fake backgrounds are truly behind me now).
So #1 and #2 might be salvagable if I take a bit more care in the editing. #3 is actually part of a fairly decent half-body portrait which I just liked the look of blown-up, so that ones done anyway. But #1 and #2 I never expected to be able to use for anything, so Alien skin have definitly made me happy.
Thanks a lot everyone!
EDIT: Plus really stupid question time, is 'punch' controlled exclusively by contrast, or is there other ways to increase impact? I'm thinking vivid colouring, which isnt going to help me with B&W, but is there other methods?
