Brightness
Brightness is the overall lightness of the image. Move the slider left or right to darken or lighten the image.
Adjusting the brightness level adjusts the tone of the pixels, without changing the true color of the pixels; such as
when adjusting hue.
Choosing brightness values
Adjusting the brightness level is based on how you want the image to appear and there is no standard to adhere
to. Below are some recommended options for brightness image correction based on the original document
quality.
• Original documents of good quality - 50%
• Pencil written letters, forms, or drawings - 25% to 40%
• Faded pictures or old documents with faded text - 35% to 45%
• Light colored carbon copy paper, such as yellow or pale pink or pale green, with light text - 45% to 55%
• Newspaper or magazine pages - 55% to 70%
• Book pages - 55% to 80%
• Pictures taken inside or in the shade - 60% to 85%
