I have a nikon d90 12.3 mega pixels camera. I have the save settings set to the highest quality RAW. But most of the pictures i have taken are between 9megs and 10megs. I dont understand, should'nt they be larger because it is a 12.3 meg camera or am i missing something. I have also noticed when i view the pictures in the View NX software that came with the camera, The picture info on the left side of the screen says Image Quality compressed RAW. I thought RAW was an uncompressed format. Could someone please enlighten me on this. Thanks.....signed Randall

Megapixels do not equal megabytes

The RAW files can be compressed without losing any data, which is different than JPEG compression, which does lose data. This is why compressed RAW files are still much bigger than JPEG's. RAW compression is kind of like zip, where you can reduce the size of programs without corrupting them.
