Hi Terry Brown. Presumably the scanner you are using has a slide adapter. If it hasn't, then you need a scanner with this utility. If it has, then what graphics editing software are you using? After setting the brightness and contrast to make the blacks black and the whites white, experiment with the gamma value. You shouldn't need to adjust gamma outside the range of 1.00 to 2.00. I find adjusting the gamma generally gives a more pleasing result than simply adjusting contrast.
