Cokin Infrared 720 (89B) Filter - 84mm

No, this is a technical filter specifically for infrared effects and will result in distorted colors or blacked-out images if used for standard photography.

Yes, but digital camera sensors have internal filters that block some infrared light, meaning you will need longer exposure times compared to infrared-converted cameras or film.

89B refers to the classic Wratten filter designation which defines the specific transmission wavelength (720nm) of the infrared filter.

Shoot in RAW, convert to black and white, and experiment with 'Channel Mixer' adjustments in your software to emphasize the reflected infrared light on leaves.

This 84mm filter is specifically designed for the Cokin P-system rectangular filter holder, not for direct screw-on use unless you have a specific holder adapter.

This is normal given the high light-blocking nature of the filter. Increase your exposure time (shutter speed) or open your aperture wider.

Infrared light focuses differently than visible light. Focus your camera before attaching the filter, or use manual focus to achieve a sharp image.
