Photo File Size - Daft Question?

[cobra kid]

If a digital camera takes two photos in quick succession, with identical settings, why do the files have different sizes? A pixel is a pixel....

Generally JPEG. I find it on all cameras.

JPEG is lossy compression and depends on the image. A picture of a black wall will compress very well indeed.
