Re: filmscanners: (anti)compression?



This is probably a stupid question, but how do you do an LZW compression on a
TIFF file?  Photoshop doesn't offer TIFF compression as an option, as far as
I know.  Is there freeware available?  Since a lot of my work involves models
against a solid colored background, it seems like lossless compression would
save me a lot of storage space.  I assume you have to run a stand alone
decompression program to get the original file back.

That is because LZW works by substituting colors with variables. If you have
an image with very few colors and shades, LZW will compact it to a tiny
fraction of its original self. On the other hand, a very diverse image with
lots of colors and shades will require tons of substitutions, and the size
becomes larger.
