How to use Grayscale mode

You can find Grayscale in the "Edit Image" tab. Select "Levels" and then "Grey Scale." The pictures will automatically lose its color (if it has) and transform the picture's look into black and white or in gray. Also, you can manually balance the level of Grayscale by selecting "Levels" from "Edit Image" tab. Select the tab "Brightness" then drag the moving object to either brighten or darken your picture.
