Need help choosing a lens for a home made box camera.

[Bob Salomon]

No problem jb7, all in fun, heck I`ve already bought half a dozen lens that didn`t work. lol.
I`m interested in this contact printing.

To contact print you put the negative, emulsion side down, onto the printing paper, emulsion side up, sandwich them tightly between glass on the negative side and a board on the paper side and expose the sandwich to light, seperate the sandwich and develop the paper.

Thanks Bob, I take it you meant board behind the paper, I`ll give it a try.

How do you use that paper, everything is done inside the camera with this rig.

NEVERMIND.. I now find out it is no longer produced

Thanks for the info anyway, I`m heading to my closet darkroom to try out the contact method.

While I`m trying that I have another question, if ya notice in my pictures that I posted on page one that some are pink.
That happens as soon as I take the picture out of the camera while outside either in the sun or shade. Doesn't do it in the house.
What causes that, I`m putting the photo in developer then a vinegar water mix.

you'll need fixer after the vinegar/water bath

did you not want to make copy photos to reverse the negative like they do on the street in Afganistan?

the contact method will make better prints, but shooting the original is cooler and more original

Yep, I have some fixer just haven`t used it yet but why does it only turn them pink outdoors?
I do want to do it the way the guy did in Afghan, I bought that 6x9 camera on Ebay hopefully it will work out.

Here`s the video of the Afgahn camera.

The image I posted of the Afganistan camera shows a 135mm lens. To make an enlarged positive for the customer, the same 135mm lens, with an object 8" from the lens, will make an enlargement at about 16" behind the lens. I don't know why you would want to use a shorter lens and make a same-size print tiny print.
I don't know why your images are blurry. How are you focusing. Are you placing the paper at the exact (to the sub-millimeter) plane on which you focus?

I don`t want a tiny picture, I`ve been told the positive picture is blurry because I`m using a magnify glass for a lens.

I tried the contact method from a negative of me and it worked great with a 15 second exposure to a light bulb.
Yours truly.



20 second exposure

Thanks for all the help, I`ve learned a lot here already and will post results after I get the new lens.
