Arkadiusz Mlynarczyk has released ColorWash 2.1.1 (http://arek.mlynarczyk.info/colorwash/), an update to his photo enhancement tool for Mac OS X. It requires Mac OS X 10.6 or higher, costs US$0.99 and is available at the Mac App Store in the Photography category.
ColorWash lets users transform ordinary pictures into “artistically dramatic photos.” Snapshots are automatically converted to grayscale when loaded then users are able to select which elements within the scene will be restored to their original color. The latest update features a brand new fill tool, as well as allows direct upload to Facebook, Flickr, and sending via email.
