Question: Why do the jpeg files differ in size?

Some jpeg files are 3.5 MB and others 5.9 MB. Why is that? All were shot horizontally.

Answer:
Answer:

Jpegs are compressed image files, and the amount of compression and therefor image size will depend upon what's in the image - an image containing, for example, a lot of blue sky (so a fair amount of the image is a uniform colour) can be compressed a lot more than an image of, for example, a crowd of people in fairly poor lighting
