MiNT Flash Bar is definitely interesting device and I do recommend it. There's two settings in the back, the flash has a what they call a neutral density compensation mode so it allows you to shoot with 600 films!
Inspired by the SX-70, Gary and his team of 100 spent two and a half years developing the world’s first twin lens instant film camera InstantFlex, TL70. After uncountable attempts and mistakes to turn ideas into a tangible product, the InstantFlex TL70 launched in March 2015.
Over the years, Gary and his team have saved thousands of Polaroid SX-70 & SLR670 cameras from the scrapheap. MiNT extended not only the useful life of these models, but also enhanced their functionality, by designing accessories such as flash bars, timers, filters, and lens sets that offered more possibilities for creative expression. Then in 2015, MiNT invented the world’s first twin lens instant camera, the InstantFlex TL 70, followed by a 2.0 version a year later. Quietly, and patiently, MiNT is revolutionizing the instant photography landscape.
This camera has the best image quality from any instant camera. Past or present. The viewfinder is Leica-bright, SLR and has a split image circle. It still has the great ‘folding into a compact body’ ability. As the Polaroid SX-70 had. And it’s simple to use. No digging through menus.
As you all may already know? Every time you take a picture using the impossible films, the color turns out to be yellowish and orange color. So here're the tutorials for you to improve it.
