So what do you choose then if you have TWO of each size? Like I have a 4:3 (12 M) that's 4032x3024, and then right below it, I have a 4:3 (6.2 M) 2880x2160. The same goes for the 16:9 s. And the 1:1s! It seems like once again it's just size, but why have the same ratios but different pixels I'm assuming? Any guidance is appreciated. Thanks!
