I'm getting ready to use my d2v for the first time, and I was tinkering with it last night. I bought a set of kodak polymax filters with the enlarger when I bought it, but now that I look at it I'm not sure where to put the filters. It doesn't look like there is a filter drawer per se, can you simply put them in the spot where the variable condensor lens goes (below the light source)? They seem to fit there pretty well. Thanks.
