in which Lee shows you how to make this shadow thingy with a smudge wherever
—I did come up with this (I'm pretty sure) so credit me if you use it!—
————————————
S U P E R I M P O S E:

1. Open up a white background (or any color of your choice, honestly)
2. Open up your PNG as the foreground. Move it to the left or right (slightly) of the center.
3. Filter>Settings>Contrast-Turn it all the way down for the gray shadow effect. Turn the exposure all the way down instead for black. Turn the exposure and brightness all the way up for white. For any other colors, go to the pyramid of three circles and just play around with the colors until you have the one you want. Turn the contrast all the way down to make it that solid color.
4. Merge your PNG.
5. Open up the same PNG, put it to the center or wherever you want to for your desired affect. Merge.
6. Open up the next image as your foreground, go to transform, and put it on Multiply. This will make it look a little more blended.

7. Size it to your liking, tilted, low, high, however you want. Merge.
8. Save the photo, go to Phonto, and add your title and jazz.
