Re: [pinhole-discussion] focusing loupe and focusing cloth
These are the ones I used... http://www.homedepot.com/cmc_upload/HDUS/EN_US/asset/images/pii/1/5/4/0/A704 51_3.JPG 3 mil thick.. plus i didn't cut them at all so it was actually 6 mil (3 mil x the 2 walls of the bag) thick. seemed opaque to me but i don't remember how much I really scrutinized it since it was just for a camera obscura and not a darkroom. rob From: Andy Schmitt aschm...@warwick.net Reply-To: pinhole-discussion@p at ???

Re: [pinhole-discussion] focusing loupe and focusing cloth
I read somewhere that if you draw a cross on the ground glass with an H lead pencil and stick a piece of glass slide over it with canada balsam (which has the same refractive index as glass and is used for microscope slides) this provides a good focusing system working on parallax or something. I think, if I can remember, that focusing one way the lines will move one way and focusing the other will cause the opposite movement. Unfortunately I cannot remember where I saw this. Perhaps some of you out there know of this method. Apparently it helps focusing greatly. By the way the folding camera plans are copied and should be out shortly.

Re: [pinhole-discussion] focusing loupe and focusing cloth
I got a really nice 10x loupe at a local tool shop - House of Tools- only $10.00. I also bought a small metal ruler incremented in .5mm , I use the ruler and the loupe to get a accurate enough estimate of pinhole diamters. Gord

Re: [pinhole-discussion] focusing loupe and focusing cloth
Hi leezy, I'm sort of puzzled why you would need to darken the windows of a DIGITAL darkroom, but I'll put that aside. For darkening the windows of the darkroom, I use an opaque white cloth available from fabric and decorating shops; it's called blackout cloth. Its nominal use is as a lining for bedroom curtains, for people who like to sleep in and don't like the light in their eyes, but it serves beautifully for our purpose as well. I like it because when the lights are on the white cloth makes the room seem light instead of like a cave. For a focusing cloth, I use a good quality (tightly woven) wool twill; it's much lighter in weight than the blackout cloth I described above, and it folds down nicely for carrying, but also has enough substance to it that it doesn't blow around in a breeze.

I need something that will work reasonable well with a 4X5 view camera, but am not interested in spending too much, obviously. I have a finney that I am experimenting with using for lens as well as pinhole work.. Any tips appreciated, Jeff What I did was, go to a local fabric shop , and searched for black cloth , something in a cotton blend ( so it could be washed ) and got double the amount( reason being one thickness did not screen out the light totally ), folded it over in half, then sewed seams all along the edges ( I had a friend do this part) and voila I had a focusing cloth for my 4X5 . I suspect you could buy a black piece , and a white piece to sew over it , to keep out the heat while focusing in summers , since then I have purchased a really nice focusing cloth from the View Camera store in AZ. ..It fits snugly around my view finder by means of elastic, but the price was about $54 .00 maybe, cant recall, but it is one that will last and take some abusing over the years , you could probably sew in elastic to the pieces of cloth you purchase, too. At the cheap end of the spectrum , I used to use an Agfa loupe , dunno what the price is now, (maybe around $6.00-8.00 now,) its power is about 4X as I recall , maybe 6X , since it is plastic, its not the sharpest, but it works, also I just bought cheap magnifying glasses to use too, but always seemed to lose them , so bought the Agfa loupes instead. Hope this is of help to you .
Re: [pinhole-discussion] focusing loupe and focusing cloth
I don't know about a focusing loupe but any tightly woven no lint black cloth should do. The heavier and finer the weave the better. Probably a good try would be raincoat material. You want it pliable and easily foldable. You could use fake leather or bookbinding material but this is awkard to fold making packing a difficulty but perhaps more importantly folds and the hang of the material do create natural light traps which will make focusing easier, especially in conditions of bright light. alexis on 4/1/02 4:39 am, Jeff Dilcher at dilc...@hiddenworld.net wrote: Anyone have any good / cheap suggestions on how I should go about obtaining a focusing loupe and focusing cloth?
