Sets the MTF (Modulation Transfer Function) level. When the CCD converts the original image
to electrical signals, the contrast is reduced due to the influence that adjacent white and black
pixels have on one another as a result of lens properties. Typically, you will see very narrow
width and spacing between black and white areas. MTF corrects this problem and emphasizes

image detail.
For each adjustment below:
• Weak: Low end of the range (0)
• Medium: Center of the range (default)
• Strong: High end of the range.
