This gallery was taken with a modified Canon G1. The camera's hot mirror was replaced with clear glass and a Hoya R72 near-infrared filter was used.      Removing the hot mirror gives you normal shutter speeds, allowing handheld infrared photography and the capture of people and other moving objects.      Where the factory G1 with the Hoya R72 filter achieves perhaps 1/20th of a second on sunny days, the modified G1/R72 combination is at 1/250 - 1/500th of a second. But every solution creates a new problem -- or at least a trade-off -- and that's certainly the case with the modified G1.      I've gained faster shutter speed but I've lost my green-tinged plants. Rather than the localized light-green color I was getting on foliage, I now get, at best, an overall pale-green hue to the entire photograph.      Interesting, but not very. Another problem I noticed was a lack of contrast compared to the stock G1 infrared shots. Fortunately, this can be cured with the contrast setting in Photoshop -- a feature I'd never had to use before.      Life is a compromise, especially in our photographic tools, but I'm happy with the G1 compromise so far.      The loss of green was well compensated for with the expressions on these protesters faces -- and my ability to stop their whirling white balls in mid-air.
