Tips: Choosing the Black Point, White Point, and Mid-Point
Adjusting brightness: To make the image
brighter, move the mid-point to the
right. Moving the mid-point to the left
makes the image darker.
Correcting exposure: If the image is over-
exposed, move the black point to the
right until it lines up with the darkest
pixel in the histogram (see right). If
the image is underexposed, move the
white point to the left until it lines up
with the brightest pixel. You can then
move the mid-point left or right to ad-
just brightness.
Correcting overexposure
Increasing contrast: To increase contrast,
align the black point and white point
with the darkest and brightest pixels
as shown at right. You can then move
the mid-point left or right to adjust
brightness.
Cautions
• Level correction is available only with still images taken with this
camera. It is not available with movies or pictures taken using S-
Cont or M-Cont. The desired results may not be achieved with
monochrome images or photographs taken in text mode.
• Although level correction can be applied multiple times, the
compression applied every time a copy is saved will result in a
drop in image quality.
