Does anyone know of any sites that deal with the possibility or otherwise of usefully applying the ZS to the processes of digital photography? Robt (who knows) mentioned something in passing in the other thread, and I've been searching around for a bit but can't find anything ...
Beyond that, does anyone have any thoughts on the process as it might apply to the digital world? I'm pretty much a novice with this stuff, and would really be interested to hear others' thoughts.

| I think iif your digital camera is equipped with a histogram feature (something A.A. did not have), it becomes really easy to adjust the exposure to the correct value which covers the full tonal range, without knowing anything about Zone system. However, if timing is critical and you don't have a chance to check the histogram and re-shoot, it does help to understand spot metering and exposure compensation (which is, in essence, the zone system) |

That's a pretty good link. It deals with the overall tones of the image, and how to use the camera's built-in spot meter to "place" your white value, which is what you need to do with positive (as opposed to negative) imaging. The link closely parallels how I make my exposures.
The "Zone System" I have been mentioning in passing that I am trying to develop is all in the computer, and is an attempt to work with individual colors within the image and quantify how this can be done. I want to be able to precisely arrange the luminance of the different colors. It's nowhere near ready to be "revealed" at this time.

Perhaps Daniel's previous thread ('PS tips for the semi-advanced') will give some food for thought.

/edit: I really should check my favorites before posting links. Richard Chang has a very relevant article, "Digital Zone System".
/edit again: Another, to provide a broadened perspective: Eric Kahler's "The Digital Zone System Foundations".

Digital cameras are not at all like shooting film negatives. The best advice is to expose as high as you can with out blowing out the highlights, the histogram will tell you if you are blowing out the highlights.
When shooting film you tend to want to over expose a bit when there is a lot of dynamic range in the scene, not something you would every do with a digital camera.
Since you are not shooting 8 x 10 sheet film the other advice is to bracket your shots

Bahman Farzad has written a couple of books that could help:
1) The Confused Photographer's Guide to Photographic Exposure and the Simplified Zone System
2) On Camera Spot Metering
