Ah, I remember this photo! This came from a series of photos that I did as a lighting experiment with colored cellophane over lights. I placed the glass in a light box to diffuse the lights.
I was mostly going to a silhouette effect, like this photo from the same series.
I was just starting to flex my experimental photography muscles in this shoot from the spare bedroom in my apartment.
If interested, here’s the flickr page for the featured photo, including the EXIF data.
