[QUOTE="WayneF, post: 541530, member: 12496"] This is all really easy.. Here's a quicky to show the point. Yes, I could have planned it a bit more carefully. :) Four pictures. The flashes are 12 feet from the house. Two pictures 4 feet from flashes, and two at 12 feet. One each of those was 24mm lens and one each was 120 mm lens. [IMG]http://www.scantips.com/g2/801_2092a.jpg[/IMG] Here they are cropped and enlarged, to be able to see it. Trust me, I was very careful. Or much better, simply do this yourself so that you will believe it. It's a very good thing to know. [IMG]http://www.scantips.com/g2/801_2092.jpg[/IMG] 12 feet 120 mm - the flashes are roughly the width of the narrow brick separator. [IMG]http://www.scantips.com/g2/801_2093.jpg[/IMG] 12 feet 24 mm - very different lens, but at the same distance, so same perspective. Other than the overall angular view of course, it is the exact same view (if from the same position). [IMG]http://www.scantips.com/g2/801_2094.jpg[/IMG] 4 feet 120mm - the flashes are roughly the width of the window and the separator. Note that at 4 feet, the near flash appears a bit larger than the far one (flash mountings are 7 inches apart). Imagine if that 1.25 inch hinge circle was a nose? You might never notice it, but your wife definitely will, to the extent of not liking how you made her look. This is Perspective. [IMG]http://www.scantips.com/g2/801_2095.jpg[/IMG] 4 feet 24 mm - very different lens, but at the same distance, so same perspective. Other than the overall angular view of course, it is the exact same view (if standing in the same position). What else could we possibly expect? :) 24 mm saw a much wider view and a lot more sun on this last one, mostly the central black flashes became a more minor effect, so the A mode exposure fell back a stop. I left it, it was not my point. Note that the two 120mm pictures do not look alike, and the two 24 mm pictures do not look alike, because the lens stood at different distance locations. However those lenses standing at the same distance location saw exactly the same view there. How else could it possibly be? :) Perspective is the relative appearance of items in the scene (like the flashes and the house here, and of course like noses, which is a concern of portraits). Perspective is only about where the lens is standing (i.e. the view seen). Perspective is NOT about the lens. Any lens merely captures what it sees there, what else could it do?
