>...you mean the likely hood of having an over/underexposure situation is decreased, if the range of the camera covers all values in a scene.<
>If your exposure is accurate within +/- 2.25 stops, the range should have you covered?<
If I understand you correctly, to state ±2.25 stops would not be correct because the scene could naturally be very bright and hence for an accurate exposure the histogram would be skewed to the right, resulting in, say, +1 stop/-3 stops lattitude in error on the part of the photographer without overexposing/underexposing the scene. In any event, a quick inspection of the histogram will tell you immediately if the image is overexposed/underexposed.
>Initially I was thinking in terms of an incident meter exposure where zone V would be exposed for zone V and all the other zones would fall within the latitude.
About the sum total of my knoweldge of the zone system is that it was devised by Ansel Adams. You've lost me. No need to explain though, as I am not about to adopt that system.
