Virtually all conventional digital cameras are manufactured today with “hot mirror” infrared cut-off filters specifically designed to block infrared light from reaching the sensor. That’s the challenge for infrared filters like I-Rays — to produce infrared images in cameras designed to block infrared light!

Jump into the exciting creative world of infrared photography with Singh-Ray’s revolutionary I-Ray filters — without the cost of a dedicated camera and conversion — or the need to lug extra gear into the field. I-Rays are also great creative options for those with 590 and 665 converted cameras.

Virtually all conventional digital cameras are manufactured today with “hot mirror” infrared cut-off filters specifically designed to block infrared light from reaching the sensor. That’s the challenge for infrared filters like I-Rays — to produce infrared images in cameras designed to block infrared light!

Now we offer you two exciting filter options. First, our 830 (Standard) I-Ray, for producing the dramatic black & white of pure infrared — and our 690 (Custom) I-Ray, to give you both black & white or pleasing “near IR” color.

Why 690?

In developing the new 690 (Custom) I-Ray filter, our initial goal was to come as close as we could to reproducing the “faux color” of a 590 converted camera, while dramatically reducing exposure times. What we discovered was that the built-in infrared cut-off filter in today’s digital cameras blocked the very small amount of infrared light emitted at 590 nanometers, so that only visible light was reaching the sensor (and no IR effect).

So we increased the filter strength until we reached 690 nanometers. That emitted sufficient infrared light, enabling us to create pleasing infrared images in both color and black & white — and dramatically cut exposure times (depending on ISO, from less than one second to 2-3 seconds).

Our 830 I-Ray filter is engineered to eliminate visible and ultraviolet light, so what reaches your sensor is pure infrared. The result is a bold, often dreamlike image, with black skies, white foliage, silky smooth water and a number of other visual surprises, depending on your subject and location. Because of the infrared blocking filter in today’s cameras, achieving that effect typically requires longer exposures (for example, 45-50 sec. at f8/ISO 640).

“Experiment until you like what you see. There are no set formulas. But be careful, you just might find yourself using your I-Ray filters everywhere you go.” ~ Tom Bol

“For the photographer looking to explore the creative side of infrared photography without the expense and bulk of having to convert a dedicated camera body, Singh-Ray I-Rays are the ideal choice.” ~ Jason Odell
