One trick that can be used is to keep the sensor or film plane vertical and crop the result to taste, but this won't fix relative size distortions - those can only be done by getting farther away.Today’s Question: Can you amplify regarding telephoto “compression” in an image such as a row of telephone poles that look like they’re only inches apart but are in fact many yards apart when shot with a long lens? I have always heard this referred to as “telephoto compression”. View cameras with their tilt, rise, and shift capabilities can often be used to "fix" some of it but at the expense of introducing other changes, as you say. This issue of perspective distortion often is complained about by those relatively new to wide-angle photography - they don't know how to minimize it in the original photos, or what corrections work and what ones don't. The classic architecture photos with well-defined vanishing points and rectilinear perspective sometimes seem contrived and artificial to me now after years of coping with wide-angle photos. Some perspective distortions can be corrected well by software, others not so much. To a certain extent, I agree, but with reservations. But yeah, you can do stuff like make vertical lines vertical-at the expense of distorting other geometric relationships. If you mean perspective distortion, that cannot be corrected, and can only be transformed from one type to another-this is a fundamental truth independent of software, go read the section of Ansel Adams' The Camera where he shows the effects of raising the front standard instead of tilting the camera up on the resulting photos of a silo.
You can correct images from scanned slides or negatives this way. But what ViewPoint (and Lightroom) will not / cannot do: what do you mean by "wide angle lens distortion correction"? If you mean geometric distortion (typically barrel, sometimes pincushion or more complex forms), then that is not what ViewPoint corrects, that is what the regular program plus an appropriate lens profile corrects.Īctually, VP3 does have all these corrections, manually applied if you want them.
