Photoshop script for exporting layers and/or groups to separate files.
Many people want to check their “values” when doing digital artwork in Photoshop. That is, how bright or contrasty different areas of their image is. Different colors are perceived as brighter or darker than others. For example, blue appears darker than yellow, and cyan appears brighter than red. This is how you correctly preview your values using a grayscale version of your image.
