We are just starting to publish a comprehensive set of IR test pictures to
help guide you to finding the correct filters and understanding the effects of
using different filters with different cameras under different lighting and with
multiple fabrics. As you can imagine, the possible combinations are quite
large, so this may take a while.
A common question is "What is the best filter?" There isn't
any one best filter. The camera, lighting and desired effect all affect
your filter choice. There is one best filter for any particular
camera, lighting condition and effect desired.
A common misunderstanding is that the higher the cutoff for the filter, the
better. This is not true. A 715nm filter will give you better
results than a 1000nm - especially in low light situations. However, if
you are using a stock-factory camera or camcorder, you may need a higher cutoff
filter when in Niteshot mode to avoid overexposure.
Please read of FAQ for a more detailed discussion.
