I must be missing something here, but when I put the graduated neutral density filter in its slot, the bottom of the filter hits the bed of my Linhof V and does not allow proper positioning. Inserting the filter with the dark side down works ok, but the gradation is reversed. Thanks for your help.

It's designed to be long so that you can have a lot of flexibility in where the graduation is placed... as you've discoverd this can get interesting with flat bed cameras (where the rear standard cannot be moved forward as an alternate focus).

You might try dropping the bed (can you do this wiht a V?) and tilting the front standard back (and some rise) to bring it back up...that will give you more clearance.

I have a Horseman FA and also had this problem. My soloution was to cut the Lee grads down to the same size as the Cokin P system. I can now use the Cokin adaptors and holders which are adequate and more affordable than the Lee holders. With typical LF lenses you don't need a huge filter to cover the front element. The filters can be cut with a junior hacksaw, and the edges smoothed on abrasive paper, obviously some care is needed to avoid damage.

Re above post, I should detail the method for cutting filters.
I cut a pair of steel plates to the size I needed for the filters, made a sandwich of steel plate, cardboard sheet, Lee filter, cardboard sheet and second steel plate. Clamped this to the bench and sawed just clear of the the edge of the steel plates. Saw slowly to avoid splintering and run the whole clamped 'pack' across a sheet of aluminium oxide paper on a flat surface to finish the edges. De burr the filter edge with a very fine file.
At your own risk obviously!!!

Guys, thanks for the feedback. As much as I dislike the idea of cutting a filter, it seems like the best solution. I will try raising the front standard first. ADG, do you think I could use a Dremel to cut the filter?

Before cutting the filter, you might also put masking tape on each side of the filter where you are cutting. It will help prevent the filter from shattering and minimise incidental scratches.

Morey, I am not sure about the dremel tool, I chose a junior hacksay as the teeth are very small and therefore more likely to cut than dig in and bend the material. Why not try the dremel on a Cokin filter as they are made of basically the same stuff. The Lee filters consistancy and neutral density are way ahead of the Cokin filters as I'm sure you know.
If you are not confident, ask Lee Filters, they will do it for you.

A dremel tool should work fine but bear in mind that they tend to melt plastics almost as much as they cut them. This may lead to some additional work deburring and cleaning the new edge.

Thanks to everyone, I am bit more encouraged about my filters. I am going to try the dremel and tape the area as Graeme suggested. The filters are really fun to work with and I cannot express too strongly the enjoyment of not having to fight a bright sky and a dark canyon. A bit of magic to be sure. Next question, does anyone have a sense of how much of the filter needs to be cut off? I use lenses from 90 to 300mm. Again, thanks for sharing your expertise.

It's designed to be long so that you have enough area to be able to use the filter as a pure ND filter or a graduated nd filter.

Try to find a more elegant before you cut them up.

You could always flip that puppy 90 degrees on its side, and rotate the back around to your original orientation. Bingo, the bed is on the side now.

Will...a very creative solution!! Hadn't thought of that.

For the few times when I have used all the rise I can and the bed still interferes with my Lee filter, I have done what Will is proposing....position the camera so that the bed is at a 90 degree angle. With my Toyo AII it doesn't even have to be quite at 90 since I can postion the back and lock in in place at a different angle. Just remember that what once was your tilt is now your swing, and what once was your swing is now your tilt. Sounds like a dance step!
