Thanks Allen for the effort of posting it to me. Must be this thread you are referring to http://www.largeformatphotography.in...242#post428242

[QUOTE=ic-racer;428242]Ilford recommends using the multigrade filter set with a CC40Y filter when used in conjunction with the Aristo W45 bulb. That CC40Y filter was not so easy to find, so I got a CC30Y Rosco lighting filter to place in the filter drawer.
