BTW, if you go back to http://homepage.mac.com/godders/perspective/ and look at the first through the sixth exposures, you can see the foreshortening ... the bench (which is definitely rectangular) looks very trapezoidal in the 16mm view, by the 43mm view enough is out of the FoV that you can no longer really see the perspective distortion. Also, in the same series, you can see how the angle of the camera to the porch door makes it look decidedly un-rectangular when you know that it must be a rectangle. Godfrey ============= Well, yes, that is perspective. I.E. When one draws, well, I won't bother to discuss vanishing points, because I presume people know about them. To me perspective distortion goes a bit further than that. My short cut for perspective distortion is going to be 50mm. If I can shoot something with correct perspective at 50mm, when I move in closer with a wide angle, then I may have perspective distortion. And it will probably only be a major issue for me when shooting buildings. Sometimes fine, sometimes not. Though I may find an angle/distance formula somewhere that I can understand. But formulas are often a pain to try to use, especially in the field. I know architecture photographers have to worry about this stuff. Because usually they need to represent a building the way it is. Thanks, Godfrey.
