A few tears back and as a complete newbie I bought a relatively cheap Gossen Pilot 2 analog light meter, with honeycomb cell and dial, to experiment with using a light meter. Never used it much but now I have a need. Are these things useable? The analog dial arrangement means I'm going to have to interpolate exposure times, which will be a pain, but I won't be making too many readings per session. I will be using it as an incident light meter with a built-in diffuser. Accurate enough to get me in the ball park? I hate to spring for a couple hundred bucks for something I don't absolutely need at any given time, although I'm tempted.
