    Hello:

    New at this.
    Using Irfan View.

    Can someone please explain to me exactly what the "Gamma" function is ?
    What does it do ?
    How does it do this? (what algorithm, etc. ?)

    The same questions for "Sharpen" ?

    How does Samma and Sharpen differ ?

    Thanks,
    Bob
