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?
In: Technology
Files from cameras are almost always compressed, which basically just looks for data that’s repeated in the image and only remembers it once, saving space. The more repeated data in that specific image, the smaller the file size will get.
Further more, most consumer cameras use “lossy,” compression, such as `.jpeg`. The actual process is pretty complicated, but in simplest terms it removes data from the image that you won’t notice is missing, saving tons of space. Downside is it makes professional work a little harder, but that’s fine if your just uploading to Instagram.
