Advanced Scanning
Contrast | Controls the extreme ranges of the |
| gradation curve without affecting the |
| middle tones. |
Brightness | Adjusts the overall lightness or |
| darkness of the image. |
| Move the slider bar to the right to |
| increase brightness (raise every |
| point along the gradation curve). |
| Move the slider bar to the left to |
| decrease brightness (lower every |
| point along the gradation curve). |
Highlights | Controls only the points to the far |
| right on the gradation curve. Adjust |
| these anchors with the slider when |
| you want to adjust white areas |
| without affecting shadows. |
Midtones | Adjusts the three anchor points in the |
| middle of the curve without affecting |
| the values of the highlight or shadow |
| points. When the midtone slider is |
| used, all three of these points are |
| adjusted in relation to each other. |
