There is no ideal image aspect ratio. Depending on the situation, each and every crop ratio has its own pros and cons. Personally I prefer the more landscapy 3 x 2 format, digital imaging’s equivalent to film’s classic 35mm proportions. To some it seems unnatural. Also, the more squarish 4 x 3 offers better corner performance. With all the aspect choices digital cameras offer, which one to go for? If you’re one of the few human beings left who prints photos, most labs will print uncropped if you ask them to. If you don’t specify they will usually fill the paper size or chop off the borders, notwithstanding the possibility that a group portrait of your Micro Four Thirds camera just lost auntie Ann and uncle Joe. Aspect ratios matter………
