If you start adding more layers it can get larger, I have a few composite images that are as big as 250mb, while the regular work I do to an image usually brings the file size up to 60-80mb. I work in 8bit mode, if I worked in 16 that would double the file size.

My GF's 50D's TIFFs are easily 150-300mb with out much effort.
Thanks. Helps out a lot.
