Thanks I appreciate that.
The program that I use is Photoshop 6 and I use a Wacom tablet.
Did I read in a thread somewhere about a ‘warp tool’, I just use quick mask to select the area to morph and then I skewed it on a different layer. For blending I used a combination of adjusting contrast (of the morphed an not morphed to match shades), airbrushing eraser ( for a transparent transition), and other blurs with my art history brush.
