, the way to achieve it is by
knowing the diameter of the pinhole, which in turn allow you to find the
f/stop of your set up. http://members.home.com/penate/pinhole.html has a
link to an article explaining how to measure diameters using a scanner.

interested, you have come to the
right place.
Stick around, ask questions, share what you know and please share your
images with us.

This is not pinhole.but,

hi, my name i andres and i am From argentina,
i want to make my fisrt pinhole camera, can i make one with an 35mm film?
thanks, and sorry if my english is not ok,
. Many thanks for posting it.
As for places to set up your FREE web site: http://www.tripod.lycos.com/

to name a few, and if you just want storage space try this one

Hope it helps.

and IMO can easily be used in a pinhole set up, you know, screwed to wooden
box, taped to a cardboard box, etc.
Just thought to let you people know, for the benefit os those that, like me,
didn't know this things existed.

Having said all that, unsharp pinhole images like this one, by Tom Lindsay:

1160 model, for example)
1160 is unfortunately out of production, you see some once in a while at
eBay. Its fame is so great, soon it might become a cult printer, very
much like a plastic Diana camera is today, commanding -perhaps- higher
prices than when new.

cartridges can be bought from several sources.

Again, a glass lens works in the same manner, too.

are becoming too
expensive (and scarce in some areas), he buys OneStep cameras instead.
SX-70 have better optics than OneStep cameras, but if your aim is to do
emulsion manipulation, optics quality should not matter. Anyway, that is an
alternative if your SX-70 can't be revived.

Andy,
Nice to know about that test. I'll go see if the lab that told me
they'd process 8x10 Ilfochrome free for me, still have the offer standing!
(that was 4 years ago).

some developers and fixers together with the film. I didn't mention stop bath,

, process
it and get a nice surprise!!
I don't know if people did store the camera/film on purpose, but I don't see
anything wrong in doing it purposely, it'll be like a time capsule...I
think I will do it!

interested in using to find the f/stop.

The other way around, actually. Focal distance at infinity divided by the
apparent diameter. I know that is what you meant, but thought to mention it
for clarity sake.
Guillermo
have reciprocity failure multipliers for common 35 mm films?
For manufacturer maximum suggested exposure times reciprocity corrections just
go to their web sites. I know Kodak, Ilford and Fuji have them there.

I'll post something soon.
Please do post them.

Mike, is that in the 70's as in 1970's or as in 70F or both? :-)

construction?
A shutter taken from an old camera is the easiest route, but if you want to do
it yourself, check Doug Bardell's site, his picture of the shutter alone should
be enough to do yours.

Thanks for that Guillermo,
so as understand it it doesn't matter what the shutterspeed is for you meter
reading its the f-stop
style!!
BTW, if 1 heater can't copy with the volume of water, nothing prevents you from
having 2 heaters.
Guillermo
your formula, but for the more stops of
difference the more unlikely you will.
Hope it helps,

technique works pretty well with my barrel mounted lenses, don't see why it
wouldn't work for pinholing.

Thanks for everyone who answered my query. As I stated I am having this
problem only on about 1/2 of my

Under non-cloudy day, the sun is virtually infallible, take a meter reading
using your SLR and comparare results.
Guillermo
Is it possible for you people to post an example of an image exhibiting the
mentioned problem?

Hey Guillermo,
I love your cameras! Hard to think that anybody could make pictures with
those contraptions ... But then nobody in their right mind would even think
that they actually are image-making boxes.

Basically any camera can be converted to whatever focal length you want/need.
I also have a 6x6 with a focal length of 35mm, done in a similar fashion as the
12mm above.
Hope this images gives you some ideas.
