I've shot 8x10, 4x5, spectra and i-zone polaroids.
Out of curiousity, just how do these things work?
The "professional" sheet film variety, I understand roughly. Expose the negative. Cover. Move the positive over the negative (4x5 in the camera when lowering the envelop. 8x10 in the processor). Roll. Rollers break the pod and spread the chemicals. Direct contact equals positive print. And this part is a chemical process (no light involved). Peel apart and discard negative (unless type 55).
How about the "automatic" "consumer" polaroids? How does the exposed surface (top) also become the printed surface? Is it a light process (ie. same as traditional darkroom) or a chemical process (such as the "professional" polaroids)
Anyone with good links or can explain this to me please?
