Re: [Cameramakers] Bellows Material Cordura
John, If memory serves me right I used that kind of product when making my bellows. I used it for the outside layer of the bellows. The inside is made out of blackout cloth sold by Porters Camera in Cedar Fall. You can see my camera and bellows at http://www.philsan.com/8x10.htm Phil John Cremati wrote: Has anyone tried using Cordura Nylon as the outer layer in bellows fabrication ? It is supposedly the toughest fabric on earth and is water proof...( they are using it to make Fishing Waders...) The deener 160 blend seems to be there thinnest material as they are using it for clothing. http://www.cordura.com/ Any suggestions?

Re: [Cameramakers] 8x10 camera
John, Thanks for the kind words, your other points are well taken. I centered a lot of the design around making a box to fit around the camera, that is the reason the base sticks out of the back of the camera.The design got change halfway through and I decided not mess with the base at that time. I have used it a couple of times now and agree that the base needs a little surgery to lighten the load. I will post some pics of the base when I lighten it a little. My long term goal is to make some kind of folding field camera. I took it out to a local cemetery where President Garfield's monument is and found the flat bed design to be far superior to the monorail that I built. Building these cameras is an ongoing project, but it is nice to know that you made it yourself. People that see me using this huge camera are just amazed, the thing is one giant people magnet. I spent more time answering questions the other day than shooting. Phil McCourt John Yeo wrote: Phil, Looks like a great camera, but 21 lbs! Get that thing on a diet! You could probably remove a lot of material with a drill and jigsaw, without sacrificing stability. Why do you have the back of the base sticking out behind the rear standard? It seems like that is just dead weight. You could also probably cut out the center of the base pieces like on my camera (http://www.enteric.org/810/) to reduce weight without losing stability. Overall, it looks like a great camera. I like the mechanism to lock down the front standard, and might steal it for my next camera.

Re: [Cameramakers] Making ground glass
Robert, That crossed my mind, but I find myself trying to focus the foreground or the sides of an image while making slight movements of the front or back of the camera. Still it is an interesting point since shooting a landscape pic does not need any great movements. It may be handy to have different glass to match the type of image. What I could do is mask off the glass and sandblast the outer edges at full pressure on the sandblaster and then do the center at a reduce air pressure. This may give the effect that you are thinking about. I have the sandblaster at my disposal so trying different things is fairly cheap, just the price of a $1.00 picture frame at the local close-out store. We will give that a try and see what the results are. I will take another frame to work and let you know how it looks. Phil McCourt Robert Stoddard wrote: This sounds as though there may be a tradeoff between fineness of the groundglass and brightness of the image. Maybe it would make sense to put about a 10 to 15 mm spot of very fine grind or etching at the center to use for focusing, and surround it with a coaser grind for a brighter image...RKS From: Philip J.

Phil McCourt www.philsan.com ___ Cameramakers mailing list [EMAIL PROTECTED] http://rmp.opusis.com/mailman/listinfo/cameramakers Hello All, I sandblasted a couple pc's of glass at work today and installed it in the 8x10 right away. The image is a lot brighter as compared to the acid etched glass that I had in it. The only thing that is throwing me off is the sandblasted glass has a more textured surface that shows when you look at the glass with a loupe. Shouldn't be a problem because the image is so much brighter. I had trouble seeing the image while stopped down to f45 on the acid glass. I am able to see the image much better on the sandblasted glass while stopped down. I can even see the image without the focusing cloth while at f45. My wife spotted the difference as soon as she looked at the glass. Needless to say I am going to stay with the sandblasted glass, can't wait to do a little practising with the new glass.
