An X-ray lens and a chain reaction - a photo on Flickriver

I did some experimentation with fast shutter speed and ultrafast lens on my kitchen counter. I lit up one end of a row of matches, and took this shot with an ultrafast f/0.75 vintage X-ray lens made by Kowa. This lens was built for X-ray machines, not consumer cameras, and is about three stops below an ƒ/2 lens! Daytime is too bright for this ultrafast lens, which is always fully open since it has no diaphragm.

This lens has a fixed focus distance, e.g. I have to focus with my feet, which can be challenging because the very shallow depth of field is only a few millimeters. The focus peaking feature on the Sony camera helps.

I processed a realistic HDR photo from a RAW exposure, and carefully adjusted the color balance and curves. I welcome and appreciate constructive comments.
