filters for large format wideangle lens

[Lee L]

don't you have to take the lens off the camera to do that & wouldn't you have to refocus - ?

Is there such a thing as a combination yellow filter + ND?

I'm still working on this.

Dorothy,

Remind me to bring my Voss gel holder to John's if you come down so that I can show you how to use gels inside the camera. I think a few places still carry an equivalent gel holder, but gels have gotten much more expensive.

I'm planning on coming if I don't spend all my money on more filters!
I'd like to see a Cokin X-pro and a Lee to see how they work

I just bought a Sinar camera and the person who sold it had done the most ingenious thing.

On the back of the lensboard he had glued two pieces of metal. They were c shaped, but square, so that each has a flat surface about two inches behind the board and i little behind the lens. They are steel. On each of his filters he glues two small flat magnets. Such that the filter simply magnetically sticks on behind the lens. No screws, no tape. They are fast to add or remove and can be stacked. Furthermore, there is no vignetting because they are much larger than the rearmost element on the lens.

I can post some pictures later, but all my memory cards are full and my digital camera's batteries havnt been charged in a while.

I would love to see pictures when you get a chance

What a great idea. I put velcro buttons on the back of lensboards and velcro on my 4 x 4 filter frames.

Here's a close equivalent of the Voss I use inside of view cameras. The Voss had a spring metal band (rubber cushioned) that grabs the outside of the lens barrel. This Lee equivalent appears to use a rubber band and 100mm filters. Voss made them for 75mm (and I think 100mm) filters. The Voss also had two removable "barn door" style panels for shading when used outside the camera. I removed them for use inside the view camera.

Here is a photo to describe what i spoke of before.

When I purchased my Linhof Technorama, I received a full set of Cokin X-Pro square filters, plus the filter holder that screws to the lens, and I have been very happy with the results. The Schneider Super Angulon XL 90mm f/5.6 is pretty huge as LF lenses go (105mm diameter front element once the fall-off correction lens is screwed onto the front) and I have been very happy with the results.

(as you know, the 90mm lens is extremely wide on the 6x17cm format, comparable to your ~60mm on 4x5in)

Here is an example of the Cokin X-Pro 2-stop Grad ND, in the worst possible lighting (pointed right into the sun) and there is only a tiny bit of flare, and the colours stay quite neutral:

djkloss, to answer your question, yes you can either use a "tobacco grad" filter which wil give a yellow cast as well as decrease exposure, or you can combine a warm-up filter with a Grad ND. With the Cokin X-Pro set, you can slide two filters plus a polariser into the holder, and I've never seen vignetting.

thanks for the info. I fear that there is no room left on the inside of the camera with a bag bellows taking up all the space. I took some shots on Sunday with the adapter ring and one filter at the lake. I just finished developing them so in a few days we'll see if I've learned anything from all of this.

thanks again for all your help!
