Sigma SD1 and SD15 for Digital Infrared Photography, By Jack Howard

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. A unique design advantage of Sigma’s DSLRs allows creative photographers to quickly and easily swap between visible spectrum and infrared photography.

Lilypads, trees, and clouds are highly reflective in Infrared wavelengths, as this scene from midday in Spring Lake, NJ, illustrates. Camera: Sigma SD1 with IR blocking filter removed. Lens: 10-20mm F4-5.6 EX DC HSM Infrared Filter: Cokin P 007 (89B) Infrared passing filter (50% transmission at 720nm) | Exposure: 1/80 at F/13.0 ISO 100 X3F Raw Capture. Converted through Sigma Photo Pro 5 to monochrome.
