I guess that the answer is that what happens through the lens, to the image, to the light, is far more complex than what can be corrected by simply stretching or skewing an image. When PS is correcting perspective, imo it's simply stretching the image in different degrees of intensity (skewing). That link that Das provided shows better what happens. In the case of the picture I posted here, all I did was to stretch the upper part of the image while maintaining the bottom of it unchanged. That's what the perspective tool did. So, my daughter's face got a little wider than in the original picture. I measured the distances in both pictures and then I resized the corrected image to make my daughter's face the same width it had in the original one. Then I asked myself: why do I believe that the width of the original picture (her face) reflects the reality better than the same width of the perspective-corrected picture? Well, I don't know but if I am to trust something, I'd better trust the optics then the electronics, specially since her face is in the middle of the image, where distortions are minimized. Here's a small tutorial that I found about the problem of correcting perspective using Photoshop: [url=http://luminous-landscape.com/tutorials/perspective.shtml]http://luminous-landscape.com/tutorials/perspective.shtml[/url] - BTW, this seems to me a great site about photography. Since I'm new to this forum, most probably this site, luminous-landscape, has already been mentioned here. Loading...
