Parting Shot 2

Many fantastic images are taken underwater in the tropics, but relatively few images are taken in the freshwater northern ecosystems. This is my particular interest in underwater photography. To document the fresh water lakes in all seasons, to answer questions like what does a lake look like under the ice in winter? The resulting images are used as illustration in science books and magazines. To archive images under the ice I use a number of remote triggered camera designs, as well as the age old technique of cutting a hole in the ice, holding the camera under water and taking a picture with my hands. This past year I decided to upgrade my equipment and I sold my old Nikon film - Ocean eye rig and bought an Ikelite housing for a canon 30D. The 30D is now an out dated camera (being older than a year a camera is now outdated!) and thus a lot less expensive, and I could afford a spare camera for the case. This is a big issue for underwater photographers, since each housing is unique to the camera and the housing is often equal in price to the camera. I settled on a camera and case that I hope will last me for three years.

As a scientific photographer, I often wonder what something will look like when photographed in different light. My different light was x-rays. This image is of a Ikelite camera housing for a cannon 30d with a 125 watt flash. This is the image that an airport security officer would see if you traveled with your underwater camera set up. To take this picture I used a high resolution research x-ray machine located at a local university. This machine is usually used to check circuits during manufacturing. To achieve the high resolution the machine uses a special tube that has an extremely small point source of x-rays. Lower resolution but faster machines are used in airports to check luggage for security purposes. The specifics are this image was taken at 110 kilovolts, 1.5 milli-amp current for 3 min.

I often x-ray fish, birds, snakes, and lots of electronics for science magazines, but in this case I wondered what my underwater rig would look like in x-rays.
