Exposure Latitude

Color transparency film and most consumer digital cameras have little exposure latitude.
Even slight overexposure or underexposure is readily visible, especially in contrasting
lighting. Consumer-level digital cameras blow out highlights in overexposed
prints . A blowout is a dead giveaway the image was taken with a digital
camera.
Some professional digital cameras capture 36 bits per pixel instead of 24, and are
better able to deal with high-contrast scenes than less expensive, point-and-shoot
digital cameras. Even though 24 bits per pixel means millions of color combinations
are possible, 36 bits per pixel increases that capability to billions. As a result, 36-bit
cameras capture what the human eye sees more accurately. This helps color balance
by providing more colors that can be edited and adjusted.
