images in cross-platform stacks

[Martin Baxter]

David and Richard,

Does it not also have to do with being able to discern subtleties of 
shadow detail on-screen? Uncorrected CRT Gamma (as per Win / Nix / 
Television) gives a very non-linear display and tends to compress the 
bottom 20% to black.

Images made in systems like this tend not to have any bottom-end 
information at all - it typically begins at around 20%, effectively 
reducing the dynamic range - not good for print - although possibly 
practical for consumer-oriented screen-based media.

Something else I occasionally wonder about though. Are todays LCD 
monitors configured to mimic the poor linearity characteristics of the 
old CRTs? I would guess they are, so as to be compatible with existing 
media. Presumably flat screens don't have the same inherent physical 
characteristics as a CRT? I'm interested to know what's done in that case.
