    Questions and answers

    Can I get the original look back?

    Set both sliders to 100, or start again from your original file. This page does not overwrite it.

    What do brightness and contrast do?

    Brightness makes the whole picture lighter or darker. Contrast makes the light parts lighter and the dark parts darker.

    Is my photo uploaded?

    No. It is changed inside your browser.
