Polaroid Corporation a "juggernaut of innovation", in many respects Polaroid was the Apple of its time with a "leader in Edwin Land, a scientist who guided the company as the founding CEO for four decades". Polaroid’s initial market was in polarized sunglasses — spawned from Land’s self-guided research in light polarization. Land, having completed his freshman year at Harvard University, left to pursue this market, resulting in Polaroid's birth. Land later returned to Harvard to continue his research. Polaroid, owning patents to its polarizer technology, got its start by employing polarization in products that included 3-D movies and glare-reducing goggles for dogs.
MiNT camera Polaroid SX-70 does not provide full manual control over exposure. SLR670m comes with the 'Time Machine', which enables manual control over shutter speed. MiNT re-designed the camera motherboard to provide a port of communication for the Time Machine. Shutter speeds on Time Machine range from 1s to 1/2000s plus bulb, time and auto exposure. The Time Machine only works with the SLR670m produced by MiNT, the standard Polaroid SX-70 will not respond to the Time Machine. ISO 160 when Time Machine is removed, or under Auto mode.
