Minolta X-300, 35-70mm f/3.5 Macro
The white mark at the top is a scratch on the negative, I'm useless at developing film without scratching it.
As this photos has attracted a lot of interest and speculation I'll tell you a bit more about it. It was taken in 1995 when I was doing a photography evening class. It's of my sister, Holly, who was 15 at the time. She was generally a reluctant model but the only one I had at my disposal!
I did a little set of photos of reflected portraits for my photography class. I found a broken mirror tile in a box at home and though it would make a good surface. As with most of the others from the series, it was taken upside down. It was lit with just a ceiling light. The feather thing was just something I used to cover up my sister's clothing because I didn't like what she was wearing, I think it was an old shirt.
With b/w film I generally over-exposed to increase the contrast. I remember burning this one in at the edges.
