My real name is Pete; on here and on Flickr I'm Dustin McAmera. I live in Leeds, in England.

I was promoted to be one of the admins here. If you're here in search of an admin, to ask something about CW, or complain about something, feel free to do that (best to do it next door on my Talk page).

I have more cameras than I can do justice to as a user (a few dozen), but I resist the idea that I'm a collector. That said, the pleasure of using the cameras is sometimes just as important to me as the photographs. My oldest cameras are from the 1920s, but I like to try to write about earlier stuff, just because it's under-represented here.

My own cameras include several that I feel guilty for owning, because I use them so little: in particular my Century Graphic, my Mamiya 645 Pro and my Ensign Reflex. I notice that since I started editing on here, that problem is worse.

Quite a few of my cameras are for 127 film, and I usually do something for 127 Day in July and January. I took part in a 7th December 127 Day last year, one I haven't done before; much the same experience as the January one; not enough daylight hours, and the weather was foul; but it's good to get any photography done in the deep winter. For 7 December I used one of my Zeh Goldis; for 27 January I took out a Certo Dolly (but messed up that film, somehow) and my Korelle 3x4. I've been carrying my Jubilette round in a pocket for a while, too, and I have a film from my Bobette II ready to scan, which I took (sort of) to mark Camera-wiki's first birthday.

I did Take Your Box Camera to Work Day (29 February this year) with my Duo-Ensign 2¼B (very like the Box Ensign 2¼ B but made a few years later, and Worldwide Pinhole Photography Day with my Century Graphic.

Vague to-do list

Thse are things I hope to do some work on soon-ish. Feel free to comment on these, especially if you think any of them is a really bad idea. (This isn't an invitation for anyone to insert jobs for me to do: I hate that! .. If you know enough to write one of these ideas up before I get to it, go ahead, of course.)

  • Write the Century Graphic its own page (perhaps the Crown should also be separated from the Speed too: a focal plane shutter is quite a big deal, and the lens usage of the two is different too). The CG isn't a small Speed, it's more like a small Crown; and what the hell is a flexible wire viewfinder? (Ross: if you want to do this, go ahead. I know you have one of these too! :) )
  • Check all members of Category:4x5 and its subcats: 4x5 is for 4x5 centimeter format (perhaps stupidly, since inch cameras are surely much more common); correct the cat to 4x5in where required.
  • While we're doing format categories, look up some of the stereo cameras; there are already cats for 6x13 and 47x105 I think. Check, and see if there should also be 9x18
  • Look at the Canon A-series SLRs: the AE1 page needs rewriting, and the AE1 Prog page actually says very little about the camera.
  • I have added links to related patents to some articles, especially ones on early and innnovative cameras. Patents may be available as PDF at Google Patents or Espacenet. Here's stuff to do: find out how we stand on using the diagrams from Patents. Some of these would be excellent illustrations.
  • Search the wiki for any existing page referring to the origins of automatic exposure. There are already aperture priority, shutter priority and exposure; of these, only apoerture priority comes close to what I'm thinking of. Useful links include British Patent 5608 of 1903 which describes an invention by a Max J Richter (not Max A Richter of Ernemann). It comprises a mechanical shutter, with electrical timing (the mechanical system is restrained by an electromagnet) and depending on the variable resistance of a selenium crystal to affect the time of exposure. Need to do a bit more searching to see if this patent was ever exploited, and look for other early designs. The first commercial one I know of is by Durst and fairly soon after by Agfa, using Durst's mechanism.
