I've just started making prints in my newly constructed darkroom. I've tried some printing and dodging as well. I was wondering is there a preferred time during exposure to begin the burning/dodging? In other words should you start burning/dodging at the start or end of the exposure time or does it matter?
The sequence does not matter, but I would advise to get started with f/stop timing. Once you get over the initial hurdle of learning it, it makes the whole process of dodging and burning a lot simpler. What is more important, it makes it also more consistent. Pretty soon you'll get a feel for the effect of a, let's a say, 1/3 stop burn, and you'll know how to apply it and where or when it is needed. Talking about a 2s edge burn has no meaning unless you know the base exposure time. However, talking about a 1/3 stop edge burn describes the effect consistently, regardless of base exposure time. Try it. You won't regret it!
