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.
