Classical Jpeg vs Lossless...
All digital camera do compress (with loss).

Moreover, even 8 Gigapixel camera do not have a 24 bits definitions
(and therefore, if you ever consider using povray with a 48bit PNG...)

And the glass-lenses used for the camera is either very (very very) 
expensive or just not as good as it used to be for the old chemical 
camera (the expensive one, also and at least).
