its a good idea, for the people who likes instant photos.
Just becuase nerds don't like it, doesn't mean its a bad idea.
I have the advantage of using both sides of my brain, so I can be a nerd when I want, and an Artist too.
How do you think photos are made?
Light is exposed to film to make a negative. When its developed, light is shined threw the negative to film again to make a picture that is developed in chemicals. So, its too a picture of a picture.
So this is no different.
Also there is instant photo camera (digital) andd instant photo printers out. So the market does exist, but there is a lot of iPhone users, and I am sure a lot of artists have iPhones too (brainwashed), but still this is practical idea, just not as portable.
Instand printer usually cost $100. and film is expensive. And this project is just as portable as them, but more money ($300)
