photography with infrared films.
Infrared film is also sensitive to ultraviolet rays and the shorter wavelengths of the visible spectrum so it is necessary to filter out all but the infrared rays.
IR720 passes only infrared rays above 720nm.
Infrared filters, often used in crime detection, medical photography, etc, can also be used for creative and artistic photography!

IR Powershot A630
Macro shot of my dedicated near IR canon
powershot a630. with the 720 nm pass filter. Interesting note the filter adapter for this camera came bent slightly out of round to to repair
the filter threads I forced a UV filter onto the slightly bent tube to give me good threads for the expensive IR pass filters. and to protect the threads on the new UV filter since it is now removable I added a captive lenscap to the camera ( it is sitting on the cap )
What prompted the IR conversion was that the flash worked intermittently, and as I just purchased a T3i DSLR I had no use for a point and shoot anymore. upon dis-assembly I removed the IR cut filter and found the short in the flash so I repair
ed the flash and tested it out using a piece of exposed film for an IR pass filter. with the results confir
ming the functionality I then ordered a A640/a630 filter adapter tube, since the 630 has a bayonet mount for accessories.
I also have a 900nm ir pass filter but have not had much of a chance to use this set up yet due to the changing seasons and a lack of greens to set the white balance to.

My first ever time to try infrared photography! Well not as sharp as I would have liked (next time better!! I fell in love with the process of not being able to see what you're taking picture of as the filter blocks nearly all light out...so once it appears on the screen, it' s like developing in the darkroom and waiting to see what comes out!!) but I like the overall effect...
The wind was quite strong at times and with 13 seconds of exposure you see the tree seems to be out of focus.
(Really needs to be viewed large to see there are some sharp bits in the forground! LOL!)
I used HOYA infrared (R72) PITCH: 0.75 filter for this
Exposure: 13 sec
ISO Speed: 50
