Datasheet
These two special lters perform contrasting tasks. The UV/IR Blocking
Filter 486 blocks unwanted ultraviolet and infrared light components that
can produce ghost images and sharpness-reducing interference. The images
gain sharpness, detail and ne color gradations. Although digital cameras
have similar lters in front of the image sensors, there is the possibility of
residual sensitivity. A gap that is closed by the UV/IR Blocking Filter 486.
It is precisely this gap that the Infrared Filter 0 makes use of. Digital
cameras with sufcient IR residual sensitivity take highly typical infrared
picture when the visible light is blocked. The black-red Infrared Filter 0
is ideal for this task. The image section is selected and infrared focusing
performed before attaching the lter.

Whether or not a digital camera is IR-sensitive can be determined with
an IR remote control. Instructions can be found on the Internet. The IR
focus point is somewhat further away than that for visible light. With the
lter attached, white balance is performed automatically or (preferably)
manually. The IR photos are optimized in the image-processing program:
Increase contrast automatically or in the histogram, convert color images
to black and white or experiment with individual color channels, leaving
the red channel on maximum. Whether digital or analog, infrared photo-
graphy is experimental by nature.
