There are quite a number of things that can be done in photography to correct for image distortion. Would this be the place to discuss them? Or would it be better to find a photography page and link to this? I don't know how to set up a link.--Jocsboss 03:41, 31 Dec 2004 (UTC)

To some extent it should be discussed here, I believe. To add a link you just type [http://www.link.com Description]. Paranoid 08:19, 31 Dec 2004 (UTC)

I've always felt that perspective correction was just another type of distortion. If you see a low-angle shot of a building with parallel walls, it may look more aesthetically pleasing than if the walls were converging, but in no sense is it "correct" since it's a view that cannot be seen in reality.

First, some distortion is caused by the lenses, not just the position itself. Second, you are right to some extent, but the image that we see in reality is processed by the visual cortext extensively anyway. We don't see reality, we see what we believe it should look like. Two parallel vertical lines that we see may not be really parallel, but our eye usually perceieve them as parallel (even though in the "raw data" that our eye gets they are not even straigt!). So it makes sense from the aesthetical and psychological points of view to modify the images so that straight vertical parallel lines are represented by vertical parallel lines on the photo (unless it's a shot of a skyscraper seen from the ground-level position right next to it, where "incorrect" perspective is intentional).

To summarise: the only way to represent visual data 100% correctly is to create a hologram. All other ways are shortcuts. The traditional perspective is the most efficient one in most cases, so unless there is compelling artistic reason, the images should be perspective corrected. Paranoid 16:48, 2 Jan 2005 (UTC)

arbitrary illogic. the article is mistitled and inaccurate, pulling opinion out of the sky because it suits the preference (taste) of the contributor(s). the defense above admits that there is no possible correction in conventional image distribution, yet clings to the false term perspective "correction". this is an encyclopedia for truth, not mislabeled bias (regardless of the scope of its acceptance). if the article title is to remain, it should be clearly identified as a misnomer in the article text. ideally, the article title (Perspective correction) would become a redirect to "Perspective modification" or the like.

I've removed "Assuming that the view direction of the photographer was parallel to the land surface when the photo was made, the" As if the view direction was parallel to the ground there would be no distortion (assuming taking a picture of a tall building), but instead a whole lot of foreground 154.5.47.15
