Dubblefilm Bubblegum 200

Bubblegum is made by KONO!, the Vienna effect-film operation, in collaboration with Dubblefilm, which started as a phone app in 2013 for creating digital double exposures before pivoting to physical film around 2017. The Bubblegum stock launched in March 2018 alongside Monsoon, the brand's second wave after Moonstruck and Sunstroke arrived a year earlier. Dubblefilm has since opened a brick-and-mortar shop in Barcelona, but the film has been produced by Revolog in Vienna since the 2019 manufacturing switch.

The method matters because it is what separates Bubblegum from a Photoshop preset. KONO! uses a device they call The Reanimator that pre-exposes a roll of standard ISO 200 C-41 color negative with patterned light. For Bubblegum the pre-flash sits in the pink-to-purple range, and depending on what your lens records on top of that pre-flash, individual frames pick up varying amounts of pink, blue, or magenta cast. More even than a Yodica film, less geometric than a Revolog roll.

In use, the pink is loudest against light, neutral backgrounds and weakest against already-saturated scenes. A studio portrait on white seamless will come back looking like the photographer ran it through a candy-coated grade. Street work in mixed light reads as a faint pink shimmer. Rate it at box speed, 200. Pushing does not help the pre-flash, only hurts the captured image.

Closest peer is Lomography LomoChrome Purple, which shifts greens to purple through a different mechanism (the spectral response is altered, not pre-exposed). LomoChrome Purple is more dramatic and more consistent frame-to-frame. Bubblegum is gentler and more random.

Available in 35mm 24- and 36-exposure rolls, and a 120 format that launched a few years after the original 135. C-41 at any color lab.

The reciprocity exponent is 1.20. Zone Light Meter applies the correction past one second. A metered 6-second exposure becomes about 10 seconds at the negative. The pre-flash sits on the negative regardless of how long the shutter stays open, so long exposures dilute the colored cast against a heavier lens-recorded image.
