Re: IR filters.....

Rolland:

Thanks for all of that great info!  I was wondering....I am about to go ahead
and buy the opaque filter for shooting infrared.........I know the opaque is
#87.......i found a chart that shows how much of the infrared light is
transmitted.....87b= 940nm  37c=850nm......what is your experience with these
filters?  I am ordering the filters from B+H.....they advertise a filter for
infrared with the following numbers:  092,093,099,489.....do you know if these
are the same as the 87 series?  In the catalog I don't see Tiffen....Heliopan
or Hoya list them.....I know there is a hoyaR720......is this equal to an
opaque87?   What about Cokin?  Should I even get one?  I bought an infrared
book by Laurie White and she says to just stick with a deep red!  Then what's
the point of the opaque filter?

Please!............any input would be greatly appreciated!!!
