B+W FILTER 093 INFRARED BLACK 830 BASIC 72MM REF. 1102783

B+N Infrared Filter: The Special Filter for Extreme Contrasts.
With the B+N infrared filter, you can take advantage of the existing residual sensitization for experimental black and white photographs with high contrasts.

Leaves and green grasses are represented from light to white. A "wood effect" can be achieved with dramatic contrast between the clouds and the sky.

PRACTICAL TIPS

The IR effect only occurs with bright light
Adjust image sharpness before screwing on the filter
Check the infrared engraving (if present) on the lens
Select a small aperture
Determine exposure time using a series of tests
Use a tripod due to long exposure times
