Color Correction - Threshold

Adjusts the brightness of dithered images

In the dithering mode, the mid-tones of a photograph, are converted to either black or white based on the threshold setting. The threshold setting is the point at which a gray pixel is judged to become either black or white. The setting can be specified as a number in the range from 1 to 255.

Pixels judged to be below the threshold setting are converted to black and those above the setting are converted to white. Therefore, the higher the threshold setting, the darker the image, and the lower the threshold setting, the lighter the image.

Threshold = 128 (standard)

Threshold = 180		Threshold = 70
