Question

As the field size is increased with all other factors remaining constant, the scale of contrast will?

1) Increase
2) Decrease
3) Remain constant
4) Cannot be determined

Answer 1

Increasing the field size with other factors kept constant typically results in a decrease in the scale of contrast due to more light passing through and increased scatter.

Step-by-step explanation:

When the field size is increased with all other factors remaining constant, the scale of contrast will likely decrease. This is because an increased field size allows more light to pass through, which generally leads to a lower contrast image due to the increased scatter and reduction in relative differences in expoosure across the image. This concept is applicable in various imaging situations, such as photography, microscopy, and radiography.
