What does an IR filter do?

Infrared cut-off filters, sometimes called IR filters or heat-absorbing filters, are designed to reflect or block near-infrared wavelengths while passing visible light. They are often used in devices with bright incandescent light bulbs (such as slide and overhead projectors) to prevent unwanted heating.

Do infrared filters work on digital cameras?

Most digital cameras have an infrared blocker that’s great for regular photography, but obviously not for infrared work. The filter will block out most of the visible light, only allowing infrared through. You’ll get good results but will need to adapt the way you shoot, as the filter will be dark and dense.

What does an IR filter look like?

Infrared filters block out almost all visible light, leaving only the infrared spectrum to be captured. As such, to the naked eye the filters will look almost black, with a little red tint when they’re held up to the light.

What does a 720nm filter do?

The Standard IR Filter (720nm) This is the tried and true classic IR filter. It allows some visible light for false color, and good contrast for black and white. This is equivalent to the Hoya R72 and Wratten 89b. This filter produces the traditional dark blue skies and can also be processed for color.

Which is better b + w or deeper IR filters?

B+W contrast is lower than the deeper IR filters. When to use this filter: This filter is good for vibrant color IR landscapes, allowing the most flexibility in post processing. Also a good choice for portraits. The shallow IR shows less veins than the deeper IR filters while still creating a dreamy look.

Why are b + w filters worth the price?

Why B+W filters are worth the price. B+W camera filters have never been made by pressing the mounting ring on to the optical filter blanks like the Japanese made Hoya HD2 the “high end” and most expensive Hoya filter line. In our opinion the HD2 is now with less of a quality storage case.

Which is the best filter for B and W photography?

If your camera does not have a custom white balance option, the 850 filter still work for B&W photography. The 720 filter can still be used to get good false color results even with automatic white balance, although the results are not quite as reliable.

Which is the best filter for infrared photography?

B+W 093 IR filter 830 While the B+W 092 is a bit weak for true infrared photography (see further down), the B+W 093 IR filter 830 offers some extreme filtration that makes it a great option for mono IR photography. Appearing black (there’s no tint visible when held to the light), the B+W 093 IR filter 830 enables you to shoot pure infrared.
