Changing The Tone Curves; Applying Or Cancelling Corrections - Minolta Dimage Scan Multi Instruction Manual

CHANGING THE TONE CURVES – CONTRAST,
BRIGHTNESS, AND COLOR BALANCE
Changing the shape of a curve changes the output brightness level for each corresponding brightness level. Changing
the shape of the individual R (red), G (green), and B (blue) curves affects the color balance of the image. Changes to
the RGB (overall) curve affect the image contrast and brightness.
1. Select the color channel you want to
adjust from the channel drop-down list.
• RGB will change brightness and contrast with little
change to color balance.
R will affect red and cyan.
G will affect green and magenta.
B will affect blue and yellow.
2. Click on and drag the portion of the
curve you want to change.
• Changes are automatically applied to the preview
image.
• Click on to view the control and preview images
full screen. The Control image will be to the left or
on top.
