I recently bought a Polaroid plus and I-type film but am very disappointed with the color quality. I have color polaroid prints from 25 years ago that still have more vibrant color than these new photos. Would i be better off getting a 600 camera and using the 600 film? I'm excited to have a Polaroid camera again but very disappointed with the prints.
Polaroid went out of business long ago. The Polaroid Originals Project is a company that wound up with some OG Polaroid manufacture machines but had to recreate the emulsions.
As far as I know, the only difference between I type and 600 is the inclusion of a battery to operate the camera. The emulsions are the same. So, you will see no real difference in going from I type to 600 or even to Spectra, save the size difference. SX70, however, is a slower ISO emulsion and will have different character than I type/600...so if you want to try something new, go with SX70.
