Aspect ratio

Aspect ratio

- Aspect ratio is, of course, the ratio of the width of an image to its height that defines a rectangle of a particular size. If you're shooting square, you have an aspect ratio of one to one. Every camera has a built-in aspect ratio based on its sensor size. I have here a Fuji XT2 mirrorless camera. It's got an aspect ratio of three to two. That's pretty common. Most SLRs have that aspect ratio. Most mirrorless cameras either have an aspect ratio of three to two or four to three. You'll find similar aspect ratios on point-and-shoot cameras, cell phones and so on, so forth. There are some photographers who believe that you should never crop an image after you shoot it, that you should get it correct in frame. That's fine, better photographers than I work that way and get great work. I feel that that implies that there's some reason that those aspect ratios were decided on and those reasons are correct and well-founded…
