Polaroid SX-70 / color i-type film. During scanning, I found a short dashed-line like airplane light trail at top right corner ;). Exposure was ~8 sec.
Also, my recent night shots showed this dark-green tone at sky part, which I like a lot, at least for the moment. I think in summer it tended to be more dark blue. Is it because the night sky tone itself has seasonal difference? or because the temperature decrease affected polaroid colors? Anyway, this spontaneous thing is a fun for polaroid.
