DEAL: DxO FilmPack 3 Essential Edition available for free
New promotion between DxO and Sony. Offer ends October 31st, 2013.
It's available as either a standalone application or as a plug-in for LR, etc.
Fun thing to play around with but results pale in comparison to say a camera profiled VSCO shot. Still, its free and a great introduction to all the film emulation software out there.
