You have to watch to see if the rewind is turning as you advance the film. If it's not, you most likely have a problem. This is true regardless if the camera has a lens or a pinhole. __ Your favorite stores, helpful shopping tools and great gift ideas.

[pinhole-discussion] Finney is Back!
Hi, Eric Renner asked me to mention to the list that the Finney camera is back in production and Pinhole Resource has some. Check their website http://www.pinholeresource.com/;. Larry Bullis __ Get your own FREE, personal Netscape Webmail account today at http://webmail.netscape.com/
Re: [pinhole-discussion] Thanks for all the prayers!!!
I only was able to shoot two pinhole photos before they put me under for the surgery... I knew you were going to do that. Did you have them mount a pinhole in your skull to project an image on your brain? So glad to see you are not only over that one, but still pinholin'.

Re: [pinhole-discussion] Shim Stock
Lee, I had to call 3 or 4 stores in one city before I found one that had it. The store that had it was in the same chain as those that didn't (NAPA) and he had a huge roll, snipped it off and sold it by the inch. In another town, they (again, same chain) didn't have brass, but had copper. That's maybe even a bit better because it is easier to darken than brass. If you want the best of all materials, go to a jeweler and have them roll you out a bit of 0.002 silver. pinhole-discussion@p at ??? wrote: From: Lee W.

I'd like to get brass shim stock, but all the auto supply places around here have never heard of it. They look at me like I'm nuts when I ask for it. Do they know it as something else? Is there a better place to find it? Lee, That is its name. There are many places where to get it from. Check this page http://hornepayne.lakeheadu.ca/~gdedemet/motors56/motors11.html Another place is DoAll ( www.doall.com ), I don't think they mailorder but you may have a store near you.

Re: [pinhole-discussion] Buying Pinholes?
I can't help you if you insist on drilled holes but if you would settle for some handmade, calibrated holes in pure silver, blackened, please contact me off list. Larry Bullis kingfis...@halcyon.com
Re: [pinhole-discussion] Dissortion by the pinhole?
Sebastian, It is true that pinholes do not distort perspective in themselves; the pinhole's image is dependent upon the relationship of the point (pinhole) to the plane of projection (film). The distortion you are seeing, assuming that the pinhole is placed on the perpendicular to a (flat, not curved) film, is due to the fact that you are not viewing the image from a point corresponding exactly to the position of the pinhole when the image was made. In fact, you will probably be unable to view it that way, because unless you are using a very large camera, your eye would have to be very close (impractically close) to the image. Also, since our eyes don't see that way, you would not be able to see it all at once, so in order to see one side and then the other, you would have to change the location of the eye. If you could place your eye in that close position, it would be a lot farther from the eye to the edges of the image than to the middle, and those areas at the edges that seem enlarged when viewing from normal viewing distance, would then appear normal. I hope this is not too confusing. This applies to images made with wide angle lenses as well. The effect can be quite disconcerting, but it is not distortion. The oft-mentioned linear distortion of lenses is, for practical purposes, not really worth the mention anyway, because it is not generally visible with well-corrected contemporary optics. It is one of those things that is true mostly in theory but of very little practical importance. Larry Bullis In some books you can read that the pinhole makes no linear distortion as a normal lens does ? But the pictures of my super-wide angle pinhole camera (141°) are on the edges very distorted ! (e.g. clouds , zoom-effekt ) What does linear mean ? -- Get your own FREE, personal Netscape Webmail account today at http://home.netscape.com/webmail/
