I have a crystal hanging in my window, and because of the window aspect it catches the light pretty much all day and makes rainbows everywhere. I tried yesterday to try and photograph every colour of the spectrum being reflected at different times. It didn't work out too well - I got red, green and yellow no problem but the others were pretty much impossible!
I did however, shoot this. Which I'm really loving. I wasn't intending to get myself in the reflection (or make it look like I was holding a house) and the crystal was supposed to be the main focus of the piece but my little compact wasn't having any of it and decided that my hands and the house next door were far more interesting. I really love how it turned out though, it reminds me of double-exposed film. And I really love double exposed film.
