a couple of years ago I came across a video series on Vimeo that explained exposure, metering and the grey scale in a very easy to understand format. I bought my girlfriend a camera for Christmas (her first dslr) and I am having troubles explaining exposure and the relationship that iso, shutter speed and aperture have. Just wondering if anyone knows which video series I am talking about and where to find it again.
Well, I searched for a bit but couldn't find anything that appeared to be what you were looking for. I do like the Fred Parker site that nother poster already referred you to. An interesting Vimeo video I did see was this one:
Another concept I find useful is a simplified form of the zone system. This article is somewhat film-oriented, but it gets the basics across. There is also a link from there to a Kodak article on how to get accurate exposures with your meter that's very good.
