The most recent shot I posted to the standard gallery was of some metal tanks in full sun. With a spot meter, I was able to determine the highlight values and shadow values. How would an incident meter function in this situation for use with BTZS? Pointing it at the lens in full sunlight would completely miss the reflections from metallic surfaces, would it not?

This is still somewhat of a problem for me to understand. How does an incident meter deal with specular reflections? Do you just turn around and point it at the reflection of the light? If so, this is reflected light, not incident light. If not, how do you measure a bright reflection with an incident meter? This is an ongoing issue I have with trying to understand exposure and development using BTZS concepts.
