When CS6 was released it came with a wonderful bit of magic called the Oil Paint Filter. This technology was based on the Pixel Bender technology. It was a filter/tool that could take practically any photograph and easily turn it into a work of art. Oil Paint stayed with Photoshop for the first release of Creative Cloud, but in the 2014 release, it was removed, due to stability issues and legacy code.
I was a bit saddened by this decision (I can't paint my way out of a paper bag), so I kept the original Photoshop CC on my system, just for that one filter. Maybe a little silly, but I do love how simple it can be to create painterly effects with very little Photoshop know-how. This collection includes many images modified with the Oil Paint filter, as well as some that I converted to water color appearance using iOS apps. Enjoy.
