True for JPEG,

Entirely false for TIFF.

TIFF is a full fidelity way to store images. Of course one *can*  
store a low fidelity image with TIFF, but with TIFF one can also  
store an *equally* full fidelity image to that of RAW. TIFF (IMHO) is  
the best way to store images for archival purposes.

The workflow is this:

RAW -> lossless conversion -> TIFF

-- the key here is the *lossless conversion* step.
