I wonder how much it costs to get prints etc?
40daystogo: I am a zone system user from darkroom-chemical days, but someone can correct me if I'm wrong, but it seems to me that the provision of real-time histograms on the rear LCD of the DSLR or high-end premium compact gets me there most of the time, in terms of not over-exposing the highlights, or not under-exposing the shadows excessively. Whilst it may not be precise in terms of getting Zone VI precisely on Zone VI, the histograms serve the same end goal of giving me a tool for not blowing out highlight or shadow detail. Also, the histogram, plus the ability to roughly check exposure on the LCD act as two tools that make the Zone system procedure only really useful in ultra-precise photos where you have time to go through the mental steps, as opposed to a fast-changing situation that requires fast shooting.
Well, remember that the histogram is based on the *converted* raw image... using the white balance and conversion settings you have set in camera. These settings can have quite an effect on whether highlights are blown or not. This assumes you are shooting raw of course ;-)
