Infrared on the Trent

Thank you for reviewing my photo. Any comments and or

suggestions are greatly appreciated. Cheers

Hi Mark,

Was this processed to simulate an Infrared image ?

There are filters that allow longer wavelengths to be recorded by your Canon sensor, but they are not true Infrared wavelengths.

I have the same camera modified to allow wavelengths to be recorded to the near Infrared wavelengths with the use of special filters that would blind a normal DSLR camera.

Nice capture and nice results however you accomplished this effect.

thanks for your comments. this shot was taken witha Lifepixel modified XSI. it is the equivalent of using a Hoya R72 filter so i guess it is "near infrared". I was wondering what would I get if I put a R72 filter on the lens as well? the red and blue channels where swapped in photoshop 7 to get the blue sky.

Cheers.

Hi Mark,

Thanks for the information about you modified camera. i did not see it in the  details.

I have several cameras, mostly Nikon, from Lifepixel that I use in Forensics photography applications.

I also have several true IR cameras that can detect wavelength that normal lens glass will not pass. These are similar to what the military uses for detection of heat from distant sources, etc.

The use of an R72 or R90 would provide much improved contrast from what passes through an unfiltered lens to your modified sensor.

The use of much more expensive narrow band pass filters out to 1 nanometer is the best, but the longer exposures will often require a tripod. The lens need to be carefully selected when doing far reaching wavelength work, too.
