I posed a question in the darkroom thread about file size that Rob very kindly answered. As it also has relavence here I am posting a link.
Copy a comment I made in reply [ Now as mr. average ( no specialist knowledge of the workings of computers ) I would assume that in digital photography, bigger file size = more available actual image information in that file. Obviously now an incorrect assumption. ]
This begs the question as to how much of what we read on the net is based on incorrect assumptions wrapped up as fact.
