[Cameramakers] Flat Bed Camera Design in EIM, NOW!

2002-05-30 Thread Robert Mueller

Yesterday my newest issue of Engineering in Miniature arrived and it 
contains an article of probable interest to some readers of this group.  It 
is the first installment of The Korekta 5x4 Flat Bed Camera.  Because 
this magazine is not much oriented toward cameras as construction projects, 
but rather concerns itself with a wide range of model making and home 
machining, I suspect few users of this group subscribe so here I will tip 
you off!

The author is Richard Church and the camera is made from wood, Al alloy and 
some plastic ( Nylon Rack and pinion, at least.)  I would describe the 
design as utilitarian rather than elegant in final appearance  (Good 
plywood is a wonderful material, often lacking in the beauty of fine 
hardwoods but blessed with stability, sturdiness and availability.), though 
hardwoods are employed where they bring benefits.  Bellowsmaking is not 
involved; the author suggests buying and you all know where there are 
articles in the Internet for DIY bellows.

The camera includes a good range of movements (In front, swings and tilts 
plus horizontal and vertical sliding motions; in the rear,  only the rise 
and fall are absent.)

I will leave it to others with experience to evaluate in more detail, but 
to me the camera looks like a relatively easy one to make yet offering 
enough flexibility to satisfy most demands.  It looks as if the design 
enables good performance without too much time spent on non-utilitarian 
aspects.  It's for making pictures rather than for looking at the camera 
itself!

EIM is a British magazine distributed in the USA to subscribers and maybe 
you can turn up an issue at specialist magazine stores, but I suggest 
writing to the UK publisher if you are in an area lacking a source (there 
is an address given in the magazine for the American distributor, but no 
phone number, and no suggestion the company handles orders for anything.)

The UK email address 
is [EMAIL PROTECTED] .  There is also 
a site

http://www.fotec.co.uk/mehs/tee

which I will be checking out after finishing this!  I recommend that the 
first person who determines how to obtain the desired issues (there is at 
least one more installment a month in the future, but the first already 
contains a good fraction of the details and drawings, However, the back is 
not yet described.)

Perhaps this magazine is a good outlet for those who have made cameras and 
who wish to share their designs with the rest of the world.  The readers 
are often first-rate craftsmen and some will be building just to have an 
ideal camera for photographing their wonderfully detailed locomotives, 
etc..  Your designs might infect them with a new activity, serious photography.

Re: [Cameramakers] PRIMATIVE PHOTOGRAPHY BOOK and building your own lenes

It's a learning curve, what I'm doing is following  the suggestions in the
book, which are nicely detailed, then modify. It's trial and error, but hey
that's half the fun and frustration.

  Personally I would simply get 2 identical achromats and mount them on
 either end of the tube. Good achromats are fairly inexpensive though of
 course
 you would need a little help in defining the focal length of the
combination.
 There should be a program to help with this for simple lenses.

 Thanks!

 That is the problem. The book lists some lens surplus places, but how
 would i know what 2 lenses to buy that would work with my 8x10?

 I'm sure once you understand this it would be easy.

 Thanks

[Cameramakers] PRIMATIVE PHOTOGRAPHY BOOK

2002-05-30 Thread Kenith Ryan

Some people would ask Why build a camera?. The  answer for me is To see
if I can do it. Besides I get great satisfaction when I make something
myself rather than simply buying it. Sure it might take longer. It might
even cost more. So what.

Well,

If you build a camera, and a lens, and in my case make my own Calotype 
negative, the picture is really yours. If you buy a Nikon, Nikon lens, 
Kodak film, One hour photo processing, you were merely a tripod for that 
photograph.
