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

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 my 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.
  
They include several that I feel guilty for owning, because I use them so little: in particular my [[Graflex_Speed_Graphic|Century Graphic]], my [[M645 Pro|Mamiya 645 Pro]] and my [[Ensign Reflex]]. I notice that since I started editing on here, that problem is worse.

My own cameras include several that I feel guilty for owning, because they're so good, and I use them so little: in particular my [[Graflex_Speed_Graphic|Century Graphic]], my [[M645 Pro|Mamiya 645 Pro]] and my [[Ensign Reflex]]. I notice that since I started writing for the wiki, that problem has got worse. Recent new purchases are an [[Agfa Standard]] 208 (9x12 cm), a [[Calumet CC-401]] 4x5-inch monorail, and a quarter-plate [[Ensign Carbine]]. Another one is a Canon EOS M50; I find my life nowadays gets in the way of doing much with film, and I got this to keep a toe-hold on some photography. It's not the same; but it's a lot better than nothing.
  
Quite a few of my cameras are for [[127 film]], and I usually do something for 127 Day in July and January (July 2011 was bad; I wasted two rolls of Macocolor discovering a shutter fault in my [[Foth Derby]]).

On the other hand, the community of old-camera-owners on the web sometimes generates occasions for using them. Quite a few of my cameras are for [[127 film]], and I try to do something for '''127 Days (12 July and 27 January)'''. 2012 was the centenary year of Kodak's introduction of the 127 film size, and I think I did quite a good effort for the summer day that year. Although I've taken pictures for 127 Day since about 2005, I didn't know until 2012 that Summer 127 Day is also [[George Eastman]]'s birthday; I'm glad we mark that. We owe him a lot.
 +
I try to observe '''Take Your Box Camera to Work Day'''. I first spotted this at Flickr.  Taking my box camera ''to work'' isn't strictly possible since I changed my job (or it was changed for me) to one which doesn't tolerate such eccentricities. Instead, I take my cameras around town outside of work. On Flickr, I see there are people doing 'Take Your Box Camera to Play Day' instead, and there isn't great concensus as to when the right day is. I usually go out for Pinhole Day ('''Worldwide Pinhole Photography Day''': look for pinholeday.org) a little later in the spring, and try to do something with Light Night in the autumn.
  
My most-used cameras recently have been my [[Pax M3]] and [[Super Sport Dolly]].

==Being an admin==
 +
I was promoted to be one of the [[Camera-wiki.org:About#Active admins|admins]] for the wiki There are something like six of us: I'm first in that list on alphabetical grounds only). If you're here in search of an admin, to ask something about CW, or complain about something, feel free to talk to me about it. If you're a registered wiki user, and logged in, then you can either write me a note here in the wiki (do it next door on [[User_talk:Dustin McAmera|my Talk page]]) or you can send a message using the 'Email this user' link at the bottom of the links on the left of the page. If you're not yet a registered wiki user you can still contact me at my Flickr account, linked above. In particular, we switched off the facility for people to register new user accounts for themselves, because we got large numbers of spammers; so if you want to register, you need to get an admin to do that for you.
  
 +
Although a wiki is a kind of collective, it still has some rules (rules of conduct, rules of style, rules about copyright), and it's the job of the admins to enforce them when necessary. Please try not to take it personally if one of us changed what you wrote; but of course, feel free to ask for an explanation.
  
==Vague to-do list==
+
==Camera-related websites I use==
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.)
+
For all its faults, I don't know anything else as good as '''Flickr''' for hosting your pictures. It's where the wiki gets all its pictures. I have stayed there through several big changes. Nice little groups have formed (and disbanded). I'm still happy with what I get for what I pay. I've had a bit of a lull in my own photography, but these are the latest uploads to my Flickr account. The first pageful will all be digital stuff:
  
* Find out about more of the non-TLR Rollei cameras, and improve coverage of them. (I mean the high-spec SLRs; I have already inserted basic articles on some of the fairly recent 35 mm compacts, and the very early [[Heidoscop]] and [[Rolleidoscop]] stereo cameras).
+
{{#widget:FlickrUserH|user=54337958@N00}}
* Maybe, investigate the competitors and predecessors of the Heidoscop. My understanding is that this was a rather blatant rip-off of a Voigtänder camera. I have found several similar stereo/panoramic models as old auction lots on respectable sites (i.e. where the picture will be around for some time), and elsewhere. It's interesting, because the TLRs are obviously rather closely related to the Rolleidoscop.
 
* Find out about some of the obscure camera companies in or near Leeds. I've already added [[Reynolds and Branson]], for example, though there wasn't much about them.
 
** e.g. Taylor's Drug Company (became Timothy White's & Taylors, then just Timothy White's, which became part of Boots); Early Photography and Wood and Brass both show a folding camera, the Albion, branded for them.
 
* Find out more about Agfacolor. The name seems to have been used for more than one distinct type of film. One of these was very important indeed, and is interesting because it seems to have been one of the things done at the Wolfen plant, so may have been taken in reparations by the Soviet Union and/or the western allies at the end of the War.
 
* Also on Agfa, there is nothing about the current status of Agfa. I'm sure I have heard at least once that agfa was dead, but the products are still on the market. We should be able to say what's going on: is this really Mahn/Rollei, or Adox?
 
  
 +
Other camera-related sites I go to include these:
 +
* [http://photographytoday.net/forums/index.php PhotographyToday.net]; set up as a replacement for the NelsonFoto forum after Craig Nelson died, and the future of that site looked uncertain (it's gone now). NelsonFoto itself had its origins in Craig's dissatisfaction with photo.net. It's a discussion forum with a few dozen, mostly American, photographers. Having not-too-many contributors gives it a strong personality and the feel of a club.
 +
* ... and there is still [http://photo.net/classic-cameras-forum/ Photo.net]. It's a huge forum site, and you can upload pictures, though that side of the site is a lot more clunky than (say) Flickr. It's been sold, and moved to new software, and the amount and quality of new activity has been affected. It's still a good place to search for old posts about your own current difficulty, or see who else had posted about a camera you'd just bought. I usually search it with google (add "site:photo.net" to your search terms). Like Flickr, you can sign up without paying. I have never felt the need to pay subs, because I don't use the gallery side, only the fora.
 +
* I registered at the [http://www.largeformatphotography.info/forum/index.php Large Format Photography] forum. It's quite big and active; more than 30,000 registered users; which isn't always a good sign, but I found some useful and interesting stuff posted. Until you register, the site is a bit awkward, and my registration hung up for several days (perhaps waiting to be signed off by a human admin). There are For Sale and Wanted boards, and fora for not-large format stuff too.
 +
* There's a [http://www.5x4.co.uk/index.php UK Large Format Forum] too; not very active though.
 +
* The listings for [http://www.westlicht-auction.com/index.php?id=62&L=1 past auctions at Westlicht] in Vienna: a good place to see good pictures of some cameras that you may never see anywhere else. I have often used these pictures to check details of cameras for articles in the wiki. You can't use these pictures in the wiki, but I cite them in references. New auctions happen twice every year. I was tickled one time, to find a line of text from the wiki used in one of the auction's descriptions! Yeah - we made the big time!

(realistically, this list hasn't changed in at least a year: if you feel like relieving me of one of these guilty burdens, please do!)
 +
* I gave up on blocking Silent Users, now we don't allow people to register by themselves anymore. Also, the wiki no longer has the MergeUser extension installed, which we used to merge blocked people into the Spammer username, so I can't do that either.
  
From that page:
+
* 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! :) ''')
* 1916 Agfacolor plate: similar to Autochrome, with a random colour-screen layer of dyed granules (of what?). This is quite a long time after Autochrome (pat in 1904, on the markey in 1907) and Dufay, Paget and Thames plates using regular colour screens were all on the market by 1912.
 
  
* 1924 'Plaque Agfa, Germany': need more on that
+
* Check all members of [[:Category:4x5]] and its subcats: 4x5 is  for 4x5 ''centimetre'' format (perhaps stupidly, since inch cameras are surely much more common); correct the cat to 4x5in where required.
  
* 1935 Kodachrome, USA and Agfacolor, Germany: ''Indirect colour photography by subtractive synthesis. Commercialisation of the first chromogentic colour films. The colours yellow, magenta and cyan are synthesised during development.''
+
*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
That is, Agfa was not far behind Kodak with this idea. This is Agfacolor Neu, a positive film.
+
 
 +
*Look at the Canon A-series SLRs: I think the AE1 page needs rewriting, and the AE1 Prog page actually says very little about the camera.
 +
 
 +
* 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 aperture priority comes close to what I'm thinking of. Useful links include [http://worldwide.espacenet.com/publicationDetails/originalDocument?CC=GB&NR=190305608A&KC=A&FT=D&ND=3&date=19040204&DB=worldwide.espacenet.com&locale=en_EP 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 patented by [[Durst]] and used fairly soon after by [[Agfa]], using Durst's mechanism.
 +
Another relevant patent: [http://worldwide.espacenet.com/publicationDetails/originalDocument?CC=GB&NR=190504020A&KC=A&FT=D&ND=3&date=19051214&DB=worldwide.espacenet.com&locale=en_EP British Pat 4020] of 1905 describes a selenium-resistance circuit as part of a photometer (they don't mention photography as an application). Here, they note that the resistance of the selenium upon a change from dark to light starts fairly linear, then flattens out. They base the reading on the short-term change in resistance, to avoid the complication of a non-linear relationship, so they use the reaction of the selenium to operate a blind shading the cell after a short exposure. It's not much like Richter's design, but shows that more than one set of people thought the selenium cell was a workable idea at about this time. Search for selenium next.

About me

Hello!

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

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 my 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 they're so good, and I use them so little: in particular my Century Graphic, my Mamiya 645 Pro and my Ensign Reflex. I notice that since I started writing for the wiki, that problem has got worse. Recent new purchases are an Agfa Standard 208 (9x12 cm), a Calumet CC-401 4x5-inch monorail, and a quarter-plate Ensign Carbine. Another one is a Canon EOS M50; I find my life nowadays gets in the way of doing much with film, and I got this to keep a toe-hold on some photography. It's not the same; but it's a lot better than nothing.

On the other hand, the community of old-camera-owners on the web sometimes generates occasions for using them. Quite a few of my cameras are for 127 film, and I try to do something for 127 Days (12 July and 27 January). 2012 was the centenary year of Kodak's introduction of the 127 film size, and I think I did quite a good effort for the summer day that year. Although I've taken pictures for 127 Day since about 2005, I didn't know until 2012 that Summer 127 Day is also George Eastman's birthday; I'm glad we mark that. We owe him a lot. I try to observe Take Your Box Camera to Work Day. I first spotted this at Flickr. Taking my box camera to work isn't strictly possible since I changed my job (or it was changed for me) to one which doesn't tolerate such eccentricities. Instead, I take my cameras around town outside of work. On Flickr, I see there are people doing 'Take Your Box Camera to Play Day' instead, and there isn't great concensus as to when the right day is. I usually go out for Pinhole Day (Worldwide Pinhole Photography Day: look for pinholeday.org) a little later in the spring, and try to do something with Light Night in the autumn.

An old to-do list

There is an old list of jobs that were never done, commented out here.
