    Fred Picker recommended that the thin gelatin filters were best used behind the lens. The thinness of the gelatin was negible with regards to focus shift. I tried this for a while, but I found it maddening. Went back to the screw in filters. Like everything else, you can make it work if you either want to or have to.

    Most of the LF people I have discussed this with all say filters behind the lens seems to be the best for sharpness. But you must refocus after placing the filter do to refractions of light from he color you are using. At least that was what I was told.

    I use filters behind the lens for the simple reason that a good number of my lenses have front elements that are just plain too large for my standard 3X3" filter. Even my 100mmX100mm Sinar filters don't cover the entire front element of my Schneider 5,6 360mm lens. So, intead of carriy several sets of filters, depending on the lens size, I have one set that covers everything from my 250mm WF Ektar down to my 210mm Schneider Angulon behind the lens.

    I do my focusing and comoposing without the filter, then place the filter on the back ofg the lens using rolled up tape, replace the GG and then refocus. it's always worked for me.
