I have an Axomat 5 35mm enlarger and it does all that I need done. But, for about three years I have had a 3" x 3" square of drafting film (available cheaply in any art supply store) inserted into the filter drawer in order to convert the light from condenser into diffusion. I like the really even results. (For focusing, I simply temporarily pull out the drawer so that more light will reach the easel.) Does anyone else like this simple method?

Also, is it true that a blue light will result in slightly sharper prints, due to the fact that you now do not have to worry about all the various colors present in tungsten 'white' light needing to be focused? - David Lyga
