for black and white, i spot meter important shadows and place on zone iii - for most situations, this is fine with my developer choice. Sometimes, if the highlights fall well above zone viii based upon my shadow exposure, I pre-expose the frame to boost shadow detail with a transulcent filter and then expose to place the highlights on zone viii.

When i do shoot colour transparencies, i rely upon a 4 stop detail range and use nd grads to control highlights.
