The table shows how the kV and mAs values translates into exposure points. The
exposure point system is used to easily manipulate film density and contrast.
For example:
Increasing the exposure points one step will yield 25% increased film density.
Increasing the exposure points one step with mAs and decreasing it one step
with kV will yield higher contrast but the same density.
