Which finding on a histogram indicates excessive receptor exposure?

Explanation:
A histogram represents how pixel brightness values are distributed in the image. When the receptor exposure is excessive, most pixel values shift toward the high end of the scale. This rightward shift (and potential clipping at the maximum value) changes how the image is mapped to display brightness, often making the image look more contrasted because the bright areas dominate and the midtones are compressed. So, seeing a histogram that is shifted toward the high end indicates overexposure, which corresponds to an excessive image contrast appearance on the processed image.
