It can be USED in Digital photography... well. Obviously not EVERY part of it. Zonal System involves 2 different topics: Shooting and Developing. (in synthesis) Obviously the developing part is very film-oriented. But some rules can be taken in digital post-processsing. Photoshop CS and CS2 helps a lot in this sense beacause introduce a lot of photographer-oriented tools that resembles film post-processing. For the shooting part: Shooting with the zonal system involves an in-depth analisys of the image you are about to shooting. And works. In digital i mean. I'm used to shoot images using Zonal system in film and i've used those experiences in digital too. Ah. You need a spot meter of about 5-7 deegrees spot to use this system. This is not a great problem if you have a modern digital camera with spot metering. For the ones who wanna try this technique: Just look on the net and apply a bit of common sense... you will be rewarded. Conclusion: As i've ststed before... Zonal system is a great Technique that forces you to analyze your image before shooting and can be applied on every image. Even if the Digital process put limits in this, following some rules that forces you to get the grasp of shades and lights of your images can only be a good technique.
