35mm Tricks Retro/Old Look With 35mm Film?

Retro/Old look with 35mm film? - 35mm tricks

I try a couple of pictures before the start and want photos authentic retro look, as if they were taken in the years 70 or 80 could be. When can a bit like a beginner in photography, you advise him points with the 35 mm?

I will probably buy an expired film, but I heard expired film that has been stored in the refrigerator, not very different from the normal film, so I wonder what I could to the film for this nostalgic look I 'm do.

What happens if I leave the movie (s) all day in the heat (still hidden from the light, of course)?
