This was taken with a 665nm converted 40D. Conversion was carried out by Kelvin and Jo at Protech Photographic.
I recommend them - excellent customer service - gave me good advice on which filter to go for and carried out the conversion quickly.
This shot was take with Bob Latham's Voigtlander 40mm pancake. I swapped the channels using a free third party plug-in to Photoshop Elements and then tweaked in Lightroom.
