does doubling resolution requires quadrupling (x4) the number of megapixels?
8mp is NOT double of 4mp.
4sqrt = 2
8sqrt = 2.83(not double of 2)
16sqrt = 4(double of 2)
16mp is double of 4mp.
100 = 10 x 10
200sqrt = 14.14(not double of 10)
100 x 4 = 400
400sqrt = 20(double of 10)
400 = 20 x 20 = 100 x 4
MPs | resolution
--------------------------
4mp = 2000 x 2000
8mp = 4000 x 2000(not double resolution of 4mp)
16mp = 4000 x 4000(double resolution of 4mp)
