Re: Question re. your comment on tiff.

How do you know how lossy a particular tiff is?

It depends on the type of compression. TIFF isn’t really a file format, it is a wrapper class that allows for embedding images in several formats, in a somewhat similar fashion to PDF. So, from Photoshop, for example, you can save an image in TIFF using no compression, LZW (Lempel–Ziv–Welch, which is lossless), ZIP (which is lossless) or JPEG (which is lossy).

Are dng's lossless?

There are lossy DNG formats too.
