Lomography sells a neat accessory for its Lomo’Instant camera called the Splitzer that lets you split your shots with multiple exposures. If you use the popular Fujifilm Instax Mini 90, there’s now a “Splitzer” for you.
To use the Splitter, simply set the camera to double exposure mode. After snapping the first exposure, turn the splitter 180° and then take a second shot.
The fact that you can expose each side of the photo separately means you can do things like shoot “clone photos” on instant film:
You can do this same technique with black tape, of course, but Hernandez’s add-on just makes the process much easier.
Hernandez is selling this accessory through his eBay store for $5 with $3 shipping.
