I tried the tutorial which I'd posted on January 31 for fake PS water drops. It's a video designed for making fake bubbles in beer or water droplets on the glass. They are a little too regularly and not round enough to look real. I fiddled with it way too much, using liquify to make some of the bubbles bigger--it wasn't worth all that trouble.
This is the same orchid I posted earlier--I cloned out the out-of-focus bud.
