TW, where do you get all your info !
It's great that you can post so much here

FWIW, I do remember the SLR680, but I think that was a "newer" model of the folding Polaroids.
I was so fascinated by the Polaroid cameras when they first appeared I went out and bought two !
But I think my mine were model SZ-70 (???)

My light bulb idea was to rent out the cameras for people's parties or whatever.
Being in grad school I was looking for any non-labor way to make extra $.
Nothing ever came of a business. I learned I am not a business person.
And my wife has never let me forget the $200
that used to gather dust in the bottom desk drawer.
Unfortunately a few years ago there was no more film available for them,
and they were given/thrown away...
I don't even remember them going. :yeldead:

But they were truely a great innovation at the time.

I think the SX-70(?) was an SLR that predated Polaroid's Sonar camera.

A business (that does passport pictures) were down to their last packets of Polaroid film. Would have to dispose of a perfectly good camera since nobody makes that film. Would replace the Polaroid with a new Sony to do same instant pictures.

Say what you will, I'll always have a soft spot in my heart, and a hard spot in my pants, for Polaroid. :cool:

Dr Land was a major innovator and researcher. He pioneered research on how brains do vision. For example, he discovered you can read the text or see the color. But cannot do both.

They could not understand how one section worked until someone walked across the room. Suddenly that brain part went active. Why do cats jump into leaves, then stop? Cat's vision cannot see a mouse until the mouse moves. A part that detects motion is different and better developed than another part that sees shapes. Research done by the same guy who also developed a most famous Polaroid Land Camera.

Early Polaroids came with a chemical stick to coat the film after a picture developed. Early Polaroids would literally develop a picture while watching. In its day, that was a thrill. Then you sealed that picture with a chemical (that smelled unique).

Polaroid was how we solved strange problems with spacecraft electronics. A Polaroid camera was attached to an oscilloscope to record a single trace. Today, electronics do same using digital memory. Electronics also replaced film for that function.
