Multigrade filter holder
What sort of device is available to hold the Ilford 3 1/2 x 3 1/2 inch multigrade filters on an Omega D2? I've been holding them with my fingers, but I'd prefer to have a holder of some sort. B+H has some kind of filter holder for the D2, but its dimensions / compatibility aren't mentioned.
Also, can I use a red #29 filter as a safe filter for positioning the paper?
I don't think there is one. Ilford make an under the lens filter set which comes with a holder unit which clamps to the lens barrel. But they are smaller than 3.5 inches. I think your filters are designed to fit into a filter drawer.
Your filters are designed for a filter drawer as the last poster pointed out. Here is a link to what you need and B&H has a used one for half price that shows no signs of wear. Must be very difficult to dodge or burn when you have to hold a filter under the lens. Don't know about the #29.
The March/April 2003 edition of Photo Techniques magazine had an article by William Schneider on building your own filter drawer for an Omega D-2 with a cold light. I believe the design will work just as well with the normal condenser head. In essence, the drawer was made using materials from the local hardware store and it was held snug to the head using springs that attached to the thumbscrews that hold the condensers in place.
The red 29 or even a 25 should work well as a safe filter. The 29 blocks light shorter than 600nm, and the 25, 580nm. Most Multigrade paper has little response above 560 nm.

Someone jog my memory.
BTW, if you use Graded papers you can skip the
Multigrade filters and employ brighter darkroom
lighting. Graded is blue only sensitive. Dan
You know, I have the little under-the-lens attachment for these smaller Kodak filters (which I don't care for very much). I could actually just cut the 3 1/2 x 3 1/2 filters to fit that.
Old thread revival alert....
So up until now, I had been using the small Ilford 3x3 filters in the black frames below the lens, not an issue with any of my enlarging lenses and I keep them fairly close the front. Since I am using a D2 cold light head on my 45MXT, I leave it set closest to the neg most of the time as I mainly print from 6x6, 6x12 and 4x5 negs.
Now I have a rather large 150mm Apo-N that will no longer allow me to swing the filter holder in place. So what I have gone and done is taken a spare Cokin P filter holder used normally for things like split grads and simply thread it on the 67mm front of the lens and then slide in Ilford Multi-grade 3 1/2 x 3 1/2 filters in gently, works great and I only had to trim a little bit off the filters so that they slide in with no binding.
Just an idea if anyone needs one.

No filter drawer above the neg carrier? Or no actual colorhead - so much easier!
