Over the last few days I've been experimenting with some PEF files and some files scanned from various color films. When I resize the files to the same dimensions, the scanned files are always larger (in kb's) than the files from the istD. While I know that there will always be some differences in the size of files of the same dimensions, regardless of the medium, this has me perplexed. I try to compare files with similar information, and consistently the film files are larger. I've only done this with about a dozen or so files, but I'd think that at least one or two may not give such a result. Film files are larger by about a minimum of 10%.
Files are adjusted to the same ppi, same dimensions, and saved identically to the same degree in Photoshop. Any thoughts on why this may be so? Shel
