Black Gamma - Sony NEX-EA50 NXCAM Handbook

PICTURE PROFILE

BLACK GAMMA

The BLACK GAMMA setting lets you alter the shape of the gamma curve and adjust gradations in dark areas in the image.
■
RANGE : LOW / MIDDLE / HIGH
This controls the luminance range that BLACK GAMMA
influences. The LOW setting affects the range up to almost
black, while the HIGH setting extends the range up to gray.
RANGE should be set lower when you want to control the
quality of dark areas. If you want to adjust the overall image
tone, RANGE should be set higher. At first, it may be a good
idea to start from the LOW setting.

■
LEVEL : -7 to +7
Increasing LEVEL set value brightens the image, whereas
decreasing set value makes the image darker. For example,
if you set RANGE at LOW and decrease LEVEL set value, you
can create an image with dark areas that are similar to the
ones seen in films. Unlike BLACK LEVEL, BLACK GAMMA
LEVEL adjusts luminance softly.
