Not too long ago, when I cropped, I would simply create a rectangle to my pleasing.
Now, I'm finding myself using "real" aspect ratios, such as:
3:2 (Edited, I messed up with this one, sorry)
My question is, are there any other major ones, and what is the "real" aspect ratio for a panorama?
What I mean by a "real" aspect ratio is one that works well with other mediums (I'm not sure this is quite the way to describe it).
For example, 3:2 and 5:4 seem to be the standard ratios for printing, so as long as the photo is finalized in one of those aspect ratios, when I get it printed it won't be cropped in a strange way. Same for 4:3 and 16:9, which are standard for video.
