Why YSK: I’ve been seeing an increasing number of phone photos shared online in 9:16, 9:21 or similarly tall aspect ratios, often with parts of the subject cut off. I’ve asked a few people why they cropped their images that way, and none of them knew they were cropped.
Some of the newer cameras will use multiple exposures to get more data when zoomed in. Obviously this is not as good as having a physical zoom but it can be surprisingly good compared to just cropping. Computational photography is rad.
