Perspective correction - which method for which purpose?

Hi,

I found several methods within PhotoPerfect to correct difficulties with the perspective of an image. Does anyone know, which method makes sense for which purpose. I´m still unsure about this.

Hi Ben,

What different methods do you mean? AFAIK only "Perspective" is suitable for correcting perspective distortions. It's comparable to a simulation for "Shifting" found in Tilt&Shift lenses, which is useful for taking photos of (tall) buidings.

Pincushion correction is to correct barrel and pincushion effects created (mostly) by wide-angle lenses. Do using this feature, you can correct straight lines, thus making it useful for architecture photography.

Hi Hoang-Tran,

I thought also the other options "pincushion correction" and "pincushion correction and fringe" would be part of the topic "perspective".

Even if the origins of the distortions are different, aren´t the motives concerned very similar - typically buildings/architecture? Or are there also other reasonable purposes for these features?

Hi Ben,

Yes, "pincushion correction" and "pincushion correction and fringe" are different than perspective correction, as these distortions/flaws are lens-related - on contrary to perspective distortion, which is position-related.

However mostly building/architecture are taken with wide-angle lenses, which are very prone to barrel/pincushion distortions and fringe. Thus these distortions usually occurs all together. So in the end it's reasonable to put them all onto the same multi-dialog windows. But "pincushion correction" and "pincushion correction and fringe correction" are not coherent to perspective distortion. Assuming that you have a almost perfect wide-angle lens, e.g. the new 14-24 of nikon (IMO) ;-), just perspective correction would be required.
