The BCE screen (for grayscale and color)

1 The Brightness control lets you change the brightness setting.

• Too much brightness can make an image look washed out.

• Very low brightness levels can make an image look very dark.

2 The Contrast control lets you change the contrast setting.

• High contrast can make an image look like a photocopy of a picture with little

or no gray shades.

• Low contrast can make an image look dull and flat.

3 Channel lets you change exposure settings for a particular color channel (red,

green or blue).

4 Exposure lets you increase or reduce available light to the image. This can be

used to allow more detail to emerge in an image, especially if it was

underexposed.

• More exposure can result in lighter images with more visible detail. The

higher the exposure, the longer it takes to scan the image.

• Less exposure can make an image dark and without detail.
