|The B+W filter manufacturing company, under parent company Schneider Optics, Bad Kreuznach, Germany, announces that B+W Filters for DSLRs now allow users to create infrared images. The B+W Infrared Filters 092 and 093 are available for a broad range of DSLRs.
The B+W IR 092 filter is nearly opaque, and creates infrared images that also include a portion of the visible red spectrum, resulting in dynamic infrared/pure red images, says the company. The completely opaque B+W IR 093 Infrared Filter blocks the entire visible spectrum, resulting in pure infrared photographs without the visible red component.
When using film for infrared photography, it's not possible to see your infrared image through the camera's viewfinder, thus making it necessary to develop the film before seeing the results. Results are also difficult to predict, as there are no exposure meters that are sensitive exclusively to the sensitivity range of infrared films, thus much experimenting, and use of a great deal of film, is necessary, says the company.
With digital infrared photography, it's possible to see the infrared image on the camera's LCD monitor both before and immediately after taking the shot. Many high-end digital cameras cannot capture infrared images, because professional cameras often have a built-in infrared blocking filter to improve image quality.
B+W Infrared Filters 092 and 093 are available with screw-on mounting rings to fit a wide range of DSLRs, in sizes:
- 25mm, 25.5mm, 27mm, 28mm
- 30mm, 30.5mm, 34mm, 35.5mm, 37mm, 37.5mm, 39mm
- 40.5mm, 43mm, 46mm, 49mm
- 52mm, 55mm, 58mm
- 60mm, and 62mm
The filters are $105 each
