Richard, Just to clarify, the compression is part of the file format (an option actually), it isn't applied over the top, like zipping or stuffing.
Although to complicate matters, zip is an option for compressing inside TIFFs, as is LZW and JPEG. So, just 'cos it's a TIFF don't mean it ain't compressed (Lossyly/lessly). (I know, they aren't real words! :-)) Alex May the Photons fall favourably on your sensor!
