The file size of a picture does not match the image size it was set to in the menu.

Applicable Products and Categories of This Article

The image size (aka resolution) selected in the camera menu does not relate to the file size. Image size is measured in pixels, whereas file size is measured in Megabytes. A higher image size setting may generate a larger file, but these numbers will never match because they refer to different parameters.
