How do different images from the same camera vary in file size?

617 views

Wouldn’t a camera with a constant resolution capture images of the same quality and therefore file size? How is it possible that some images on my camera can be 1.5 MB, and others 2.5 MB?

Compression, imagine you have 10 pieces of paper, and they’re all red, you could describe them as

I have 1 red paper
I have 1 red paper
I have 1 red paper
I have 1 red paper
I have 1 red paper
I have 1 red paper
I have 1 red paper
I have 1 red paper
I have 1 red paper
I have 1 red paper

Or you could just say “I have 10 red papers”, you’d convey the same message, but the message itself wouldn’t be as big, however if all your papers have different colors then you’ll actually have to describe each one of them individually and there’s no way for you to compress that, swap papers with “pixels” and factor in position and that’s pretty much how compression works
