There is no subject reflectance if the light is not inciding on the subject,
the amount of light is the first condition for the reflectance, measuring the
amount of incident light you are measuring the main factor for the exposure,
you only need to know where to put the dome and the camera, this is a a very
quick method to decide the exposure, you can judge where to put and/or the
cmaera to obtain a wanted result for most cases ; the reflective method is good
for some situations, anyway I prefer the incident light measurement method.
