Increasing filtration has what effect on receptor exposure?

Explanation:
Increasing filtration removes low-energy photons from the beam, which reduces the total number of photons that reach the image receptor. With the same exposure settings, fewer photons at the receptor mean lower receptor exposure. Filtration also makes the beam harder (higher average energy), but unless you raise exposure factors to compensate, receptor exposure still decreases.
