Sigma SD1 and SD15 for Digital Infrared Photography

Infrared photography involves capturing light at wavelengths beyond the visible spectrum. Infrared energy is reflected quite differently than we are accustomed to by many organic and inorganic surfaces, and the results of landscapes bathed in infrared light has long been a favorite style of photography for fine art photographers since the silver halide days of centuries past.
