I used homemade light modifiers for these. I used a drinking glass over one of my strobes for a diffuser on the one with the girl on the wall and a drying rack for the one under the stairs. I think they turned out great.
Also on a side note: These pictures are really pixle-y and icky looking. I saved them at 1000pix on the longest dimension and 300 DPI as Jpegs, Is this wrong? If so please tell me a better way to upload images.
