increases contrast
-
In relation to contrast, decreasing field size does what?
increases contrast
-
In relation to contrast, increasing field size does what?
decreases contrast
-
In relation to contrast, increasing filtration does what?
decreases contrast because it removes the lower end of the spectrum and removes whites
