If you use an incident meter you have three choices.
1. Take the reading in the shadows and double the EFS of the film, i.e. rate it at EFS 200.
2. Take the reading in full light and halve the EFS of the film, i.e. rate it at EFS 50.
3. Take one reading in the shadows and one in full light, average the two, and rate the film at full EFS, which would be EFS 100.
I generally follow #1 since for me the most critical parts of the scene at exposure are shadow density.
