Manual Settings lets you select a color Mode for printing the colors in photos and graphics: EPSON Vivid or Adobe RGB.
You can also adjust Brightness, Contrast, Saturation, and individual Cyan, Magenta, and Yellow color tones.
Gamma adjusts the midtone density in the print (available only when using Adobe RGB).
Fix Red-Eye reduces the appearance of red eyes in portraits.
Fix Photo automatically analyzes your photos and, if necessary, adjusts the brightness, contrast, and saturation. You can select Scene Correction and choose Auto Correct, People, Landscape, Night Scene, Sepia, or Gray.
Fix Photo (or Auto Photo Correction) uses a sophisticated face recognition technology to optimize photos that include faces. For this to work, both eyes and the nose must be visible in the subject’s face. If your photo includes a face with an intentional color cast, such as a statue, you may want to turn off Fix Photo to retain the special color effects.
Off (No Color Adjustment) turns off printer software color adjustments so you can use the color adjustments in your program only.
