It’s an other interesting thing: I have taken my first infrared photo.
There are many tutorials in the internet, which teach us use an Infrared Camera or modified your SLR Camera to take infrared photos. But those two way are both expensive, and not easy! But! I have taken infrared photos just use my Nikon D300 (SLR Camera) and One 850nm Infrared Filter (nm is one kind of units of light ray)!
As you know, Visible Light’s wavelength is from 380nm to 780nm, higher than 780nm is Invisible Light, like Infrared Ray, Radar return, radio wave and so on. Our eye just can see the Visible Light, but camera can “see” some ultraviolet radiation and Infrared Ray. For Prevent those Invisible Light interfere the imaging, almost all of digital camera have a “Stop-Infrared Ray Filter” in front of the CCD(or CMOS), the fliter stop the Infrared Ray.
If Nikon D300′s Stop-Infrared Ray Filter is the Perfact One, if it can stop all the Infrared Ray, I’ll beyond hop, My Nikon D300 must can’t take any Photo by Infrared ray! Why not have a try? I have done a very simple experiment:

Hello:
Thanks for sharing your thoughts and experiences with D3oo IR.
Did you shoot this one with your D300 unmodified just with a filter? Which filter? I guess that the Hoya R72 is not as dark as the one you should have used, right?
I am trying to buy a filter from Harrison & Harrison but I do not know how to contact them, have you heard about them.
Thanks in advance for your help.
regards
Ricardo
Yes, Just a 850nm infrared filter, I forgot the brand, But I guess it’s not important.
ISO:3200
Shutter Speed:30”
The lower the ISO number, the slower the speed. The higher the ISO number, for example 1600 the faster the speed.
If you set your digital camera to a low ISO, for example 100, the resulting photograph will be better quality than one set at 1600. The higher the ISO the more grainy the photo will look. Therefore go for a low ISO number whenever possible.
