Creative Infrared Photography - Martian Bridge

This is another example of the types of things you can do with your IR-converted camera during the winter months.

The photograph is not from Mars, but it looks like something the Curiosity Rover could have taken. Sorry for the false advertising.  By the way, NASA says the Martian sky is a butterscotch color.

The image was taken as part of a "negative space" macro challenge. I wanted an unusual entry so I grabbed the IR camera.

The photo shows a violin bridge from a three-quarter size student violin. I placed the bridge on my laptop screen and photographed it with an infrared-converted D90 (720nm standard IR filter) and a Nikkor 105mm VR f/2.8 lens. I used Aperture Priority mode at f/18, 1/13 sec, -2EV, ISO 200, and the LifePixel preset white balance. I used a tripod  to prevent lens movement.

Lighting was from two overhead halogen lamps. The initial post-processing was as described in my Before and After post except I did not use the NIK filters to darken the image.  There was no channel swap.

This image features the interesting tone-on-tone effect that is difficult to reproduce with other cameras.
