Have you ever tried to save a Photoshop document as a .png file, but .png doesn't show up in the list of options? It's probably because your color mode is set to CMYK and .png files do not support that color mode. To fix that, go into Image>Mode> and then check RGB and voila! you can now save as a .png
If you've worked in Photoshop much at all, then you probably already know that .png files allow for a transparent background which we like for our scrapbook elements!
