You can adjust brightness and contrast of the image to balance the overall tone and bring out more details in the image. The brightness control adds or subtracts colors from each pixel to make the image look brighter or darker, while the contrast control stretches or condenses the color spectrum of the pixels.

Histogram is a graph that displays the pixel distribution at any particular brightness level, from the darkest at the left to the brightest at the right. The more pixels at the left the darker the image, and more at right the brighter. For best results when making adjustments, try not to move the histogram beyond the right or left edges to avoid color distortion.

To adjust the brightness and contrast

1. Open the image in the View & Edit area
2. Choose Image > Enhance > Brightness & Contrast
3. If there is a selection and the image is not in RGB full color mode, you will be prompted to convert the color more to RGB full color mode, press Yes to enter the effect mode for Brightness & Contrast
4. Experiment with the Brightness and Contrast sliders to find the best adjustment settings for the image
5. At any time of the session, press the Reset button to discard the current settings and start over
