@nanderson A friend challenged me to try Instagram. It is a challenge visualizing their square format when my current cell phone has a very wide screen. It is roughly 1:1.78 (4x7.11). That means when I put it on Instagram I lose almost half the image. That is compared to the standard 35mm film size of 1:1.5 (4x6). The pocket camera I have is 1:1.33 (4x5.33). When I post here I generally crop everything to 4x6.
