The Hipstamatic iPhone camera app is in the habit of releasing new “HipstaPaks” of gear (each one typically has a new “lens” and “film”; occasionally a “flash”) every month. Some of these disappear awhile later, to keep the available collection manageable and, I suppose, to create some artificial scarcity around their releases.

I discovered this a couple of weekends ago when I wanted the Swedish-themed Södermalm Pak and discovered it missing. I regularly buy everything they offer, not the idea of not having some drove me crazy. I promptly bought the remaining two or three I did not already have, proving their marketing technique works.

So if you also have an obsessive nature and need to have a complete Hipstamatic pack collection, this weekend will feel like Christmas has come early because they’re opening their “HipstaVault”, with almost everything from the past available once more.

As far as I can tell from Googling, the last time this happened was in 2012. I didn’t know it would actually happen again, so… predictably, I’ve now bought everything I missed.
