You obviously did not understand the gist of my post. I was asking for sources of general information on IR photography so I could decide whether or not to pursue that genre. Most of the other respondents understood my post eactly and for their input, I am most appreciative as their advice is precisely what I was looking for. As my first interest, wildlife phography, is severly limited now due to my having spinal stenosis, I thought IR photography would be an interesting facet of photography, something I could pursue despite my limited mobility.
