HT1408 - Side-by-side Comparisons

Yesterday I was talking about color space and that reminded me of another impracticality I see frequently in photography, side-by-side comparisons. For example, theoretically there may be a difference between sRGB and Adobe RGB (1998), but if that's only visible in a side-by-side comparison, no one will ever know. The same could be said about one camera and the next, one lens and the next, etc. In the real world, only photographers make side-by-side photographic comparisons.
