RE: Filters for EIR

[Sarah Morgan <sarah_morgan@xxxxxxxx>]

Helmut,
How does the polarizer affect the wavebands you pick up on your Heliopan
filter (I believe its a #29?)?  I use a Tiffon #12 which is equivalent to a
Wratten #12 and am suposed to pick up 480nm+.  Will the addition of a
polarizer or UV filter change that?

I use a Heliopan filter which is compairable to Wratten #12 Filter
and expose EIR like ISO 320/26 using the TTL metering of my EOS 600.

You can also use a KR12 color correction filter (no idea whats that
in crypic Wratten numbers) plus polariser to get slides which covers
the hole core range EIR offers you.
