This is the same chip from the last one I entered, A look into another world. This is one section of that chip. I used a 250d, 500d, +4, +2, +1, and a 35mm wide angle lens, reversed. The chip was about 3/16" away from the lens, and this was the only part that wasn't really aberated. I used a few microchip terms for the title. The "field", the measure ments are 1mm x 2mm.
