Adobe PageMaker - Controlling The Lightness And Contrast Of A Grayscale Image In PageMaker (6.5/7)
Sometimes the brightness or contrast of a placed grayscale image just isn't quite what you want. To easily tweak its lightness, aka brightness, and/or contrast, select the image, then choose Element > Image > Image Control. Change the values in the Image Control dialog box, click Apply, and you can evaluate the changes. If you don't like what you see, change the values, and click Apply again. When finished, click OK.
