I haven't shot transparencies in years. But working with JPEGs in  
digital cameras is quite similar:

- Learn to recognize, look for, and place exposure for the Zone VIII  
or Zone IX parts of the scene.
- Let the rest fall where it may, you can't do much about it
- Bracket for difficult shots so you have at least one that will be  
successful.

You can do step one in a variety of ways. I started by using a 1  
degree spot meter with an EV scale on it; that provides a measure of  
capture and analysis that is difficult to work through any camera- 
based metering system due to its specificity and restrictions. I find  
using a good incident light meter is more consistent and accurate  
overall, however, as long as you have access to the same light that  
is falling on your subject.
