Rick, I wouldn't go as far as saying Photoshop has a flaw when correcting perspective. I think it works the way it's supposed to. Have you tried using the crop tool with its option set to Perspective? The feature is rather hidden though they did publicise it when Photoshop 6 came out. I requested that the feature plus all the other perspective and distort commands, including the arbitrary feature so that it works with layers, be put into one tool but the idea was poo-pooed. I downloaded a cheapo demo of a programme mentioned here and found it had a sort of perspective tool! I think it's a programme Paul Tansley uses as a viewer. Oh, well... When you use a swing and shift, you're still using the full frame - aren't you? I have used it in film on a promo (music video) for effect but that was years ago so can't remember exactly what happens to the frame. However, if you do it in Photoshop, you have to stretch and squeeze the pixels so the result is bound to be different, I would've thought, since stretching and squeezing will add or take away pixels. If I am wrong, happy to have my perspective corrected. --/ Shangara Singh http://www.e-pixel.co.uk Adobe Certified Expert ~ Photoshop 7.0 PortfoliosOnCD for Photographers http://www.portfoliosoncd.com =============================================================== GO TO http://www.prodig.org for ~ GUIDELINES ~ un/SUBSCRIBING ~ ITEMS for SALE
