Polaroid Optics 77mm IR720 Infrared X-Ray Filter
The Polaroid IR720 camera filter is so named because it will filter out most light below and above the wavelength of 720 nanometers (Near infrared). The filter blocks most visible light and is therefore very opaque. In addition a cameras auto exposure will not work. It is recommended that a tripod be used in conjunction with this filter because exposure times tend to be quite long. When using this filter, compose your scene first, then attach the filter. Most digital camera sensors are inherently sensitive to infrared wavelengths. To prevent the auto exposure system from miscalculating exposure settings, digital cameras incorporate infrared blockers and special lens coatings. In spite of this, unique variations of uncontrollable focus, improper exposure and hot spots can create spectacular artistic effects.
Polaroid filters continue the brand's long legacy of superior optical solutions. All our filters are carefully formulated to ensure consistent color and accuracy throughout the entire surface of the glass. Why? Consistent color means consistent high quality results. We know that a poorly made filter makes a great lens and camera worthless, that's why the our frame rings are constructed of special alloys that won't expand or contract over time or due to temperature extremes-it's also why we back our filters with an 10 year warranty-because we engineer them to last.
Like all Polaroid optics, Polaroid filters are precision manufactured to the most demanding of tolerances. This ensures consistent high quality results even after years of use.

I've been playing around with my new R72 Filter. It is great. I used some birthday money to buy it. Well worth every single one of the twenty five pounds.
I asked, on the slimmest of off chances if anyone in the office had a tripod with them, and what do you know!!
These shots are f22 using a Tripod.
PS, I do realise that my sensor needs a good clean!
I am planning on using my IR filter when I go on holiday in the next couple of weeks, having only used it once before, I decided to have some fun with it. This was the result, not brilliant by any means which I accept but just some practice
