Trade Tricks: Getting It StraightCorrecting distortion of architecture in the computer |
Page 1 of 2
Photographers
know that wide-angle lenses sometimes cause distortion. Straight lines
appear curved, especially if theyre close to the edges of the frame.
Sometimes, the effect is desirable, and other times, its not. Those optical corrections are helpful, but theyre impossible to achieve without the right equipment. That means point-and-shoot cameras, 35mm SLRs and even high-end medium-format cameras arent readily able to deliver these corrections. Thats where computer software can help. Armed with any camera and almost any photo-editing program, photographers can correct architectural distortion in the computer. All you need to do is stretch and pull your pictures until those lines are parallel. |
