Lenses, films and flash generally have to be paid for and they are sold in packs, but it looks like in conjunction with the upcoming Cowboys & Aliens movie, Hipstamatic is releasing a Cowboys & Aliens freepak containing the Matty ALN and Libatique 73 lens, as well as the Steambox camera case, which gives your Hipstamatic camera a steampunk look.
The Matty ALN pack produces slightly more bizarre colors and is said to resemble an extraterrestrial’s perspective, while the Libatique 73 lens are said to produce photos that look like they may have come from 1873.
Since it’s free, Hipstamatic users should probably give it a go.
