Photographer Mitchell Feinberg has been using polaroids to take test exposures on his Sinar 8 x 10 plate camera for some years but the cost of using the ageing polaroid technology was starting to pinch. So Feinberg decided to create his own digital back for the Sinar 8 x 10 plate camera and created the worlds largest non-scanning colour sensor array.

The new digital back called the Maxback fixes directly to the back of the Sinar camera and is capable of capturing a photo in 30 seconds and creates images with a resolution of 3285 x 2611 and around 10MB in size.

Mitchell Feinberg explains how the cost of polaroids was mounting:

"I used to shoot on average 7.5 Polaroids per photo, and I shoot between 400 to 500 images a year. That’s at least 3000 Polaroids. At 15 bucks a pop. Or about 50K per year, minimum. Polaroid was at one point my highest single cost.”
