You can adjust the brightness and contrast of a picture to bring out hidden highlights or tone down areas of little interest. The top bar is the brightness control, and the bottom bar is the contrast control.

1. Select the cropping tool from the tool bar, and then select the picture whose image you want to fine-tune.

2. Choose Image Control from the Edit menu.

3. Position the pointer on the slide bar of the brightness or contrast control, and drag it to the right or left to change the brightness or contrast. You can also click the arrows at either end of a control to move the slider a little at a time and make small adjustments.The brighter a picture is, the lighter all grey values become. The higher the contrast, the more difference there is between dark and light greys, and the fewer greys there are in between.

4. Click Apply to see the results.You can make further changes, or you can undo all brightness and contrast changes by clicking Normal and then Apply.

5. Click OK when you're done.
