When people talk about giving clients a disc of High res images what does that mean? do you mean TIFFs?
Exactly, the same type of image you would print from. As opposed to an imge you might use to post on the web or one you would use as a proof.That means large size (lots of pixels) with a good dpi (like 300). Images suitable for printing.
Dpi is totally irrelevant when it comes to talking about hi-res files. All that is relevant is the file size and format. Dpi only really comes into the equation when you're talking about output (on screen or, in print).
Many photographic libraries insist on file sizes of at least 60MB. Personally, I consider anything over 1MB to be 'hi-res' or, anything above a 1024 screen based image file.
Generally printed images are output at 300dpi (although new high definition printing technologies do allow for far greater dpi). Billboard advertisements are printed at a much lower resolution simply because they are viewed from a distance.
TIFF has been the industry standard for many years amongst graphic designers and printers.
The term 'hi-res' is a bit ambiguous to say the least. I've used to use labs that would scan film to low-res, med-res and hi-res files. Rarely was the hi-res good enough for printers requirements. It all comes down to output quality and the amount of information in a file.
I spoke of dpi because I believe it was relevant to what the poster was asking...
