Canon MP-C635 Changing Gamma Curve Values

6-16 Scanning With the MultiPASS C635 Chapter 6

Consider the following example:You may wish to enhance an image

which has lost detail in the shadow areas due to excessive darkness.

By raising the lower portion of the Master curve,you affect the shadow

portion of the image without touching the mid-range or highlights.

It’s a good idea to experiment with these curves to gain the necessary

experience to use them effectively.

Changing Gamma Curve Values

Another method of adjusting the tone curves is to use the Gamma Bar.

❍Click and drag within the Gamma Bar,located above the numerical

values.
