Bodenham; Alternate Version

In an effort to show someone from work how I made my black and white infrared images with a DSLR, I had another play with this. I'm still experimenting, which makes it fun! I'm also finding new ways of altering the curves during the RAW conversion to give better results. I'm never going to achieve the pin-sharp results that I'd love to have, because of the "wavelength war" between my Cokin P007 filter and the hot mirror inside my camera.


The Cokin filter serves to block visible wavelengths above 720nm and only allow the near IR radiation to pass through. The hot mirror serves to block near IR radiation from getting to the CCD and interfering with the image. Bugger..! It is possible to have the hot mirror removed which allows for some fantastic imagery; which you can see in the infrared groups in Flickr. However, it renders the camera virtually useless for anything but IR photography. (*This can be resolved by screwing a hot mirror to the front of the lenses. See JMichaelSullvan's post below...)


Stuff that!!


There's loads of other fun stuff out there to try yet. And after all Flickr is the place for inspiration..! ;•)
