I used to shoot a lot of 35mm transparency film many years ago. Although i never owned a slide projector, i found that the colour, sharpness and contrast inherent in transparency film always appealed to me much more than prints. The downside to shooting slides, especially in tricky lighting conditions, was always exposure - you had to be spot on with very little room for error.
The first roll of slide film i ever used was East German. Orwo film was cheap (in 1991 around £3.50 a roll - process paid) and came with it's own processing bag that you sent off. I only ever used the film once, in North Wales as it happens, but I've always retained a soft spot for it. The results were pretty good -not exactly Kodachrome 25 quality like the photograph above - but adequate for a young nineteen year old photographer just starting out. Fun times.
