Pro photographers can attach what's known as a "digital back" to their film cameras. As the name implies, a digital back attaches to the back of the camera and contains a digital imaging sensor, allowing photographers to create digital images using film-based cameras.

Chinese manufacturer NINM Lab has created a twist on this, a sort of "Polaroid back." Called the Instant Magny 35, this unwieldy contraption lets you use a 35mm film camera to produce instant prints. The housing contains a single mirror, and the base is loaded with Instax Square instant film.

Because your captured image is being bounced off of a mirror, it does affect the exposure, losing three stops worth of light. This effectively turns the ISO Instax Square film from 800 to 100, which the company reckons produces that Polaroid-like look.

The downside: All of your images come out backwards--remember, just one mirror—as you can see in the awning sign in the photo below:

What's hilarious is reading the company's marketing copy, complete with grammatical errors, trying to sell mirrored images as a plus:

"People tend to be more familiar with their image in the mirror, but seeing themselves in pictures is not. However, when you use the Instant Magny 35 to capture portraits, the subject will feel more intimate with the image because this is the true 'you' that you see in the mirror every day."

Previously the company did use a dual-mirror arrangement, which produced normally-oriented images, but this made the product so bulky (see below, versus the single-mirror unit above) that we can assume it didn't sell well:

The compatible cameras are as follows:

* Nikon FM / FE / FM2 / FE2 / FA / FM3A
* Leica M3 / M2 / MD / MD-2/ M1 / M4 / M4-2/ M5 / M4-P / MA / *M6/ *M7 / *MP
* Olympus OM-1/ OM-1n/ OM-2/ OM-2n/ OM-2sp/ OM-3 (Ti)/ OM-4 (Ti)
* Canon AE-1/ AE-1 Program/ AT-1/ A-1

Note: Supports manual exposure only, does not support auto exposure or light metering mode

The contraption runs HKD $1,282 (USD $165).
