sebastian_galbo1 Posted January 26, 2007 Share Posted January 26, 2007 I want to start making pinhole photos. Can I just use Ilford Pearl paper or photographic film? How would I devolop the pictures on photo paper? Also, I had a pinhole camera out of a coffee can, I made the camera horizontal rather than vertical to avoid a curved image, is that okay? Help!Thanks! Link to comment Share on other sites More sharing options...
timswaback Posted January 26, 2007 Share Posted January 26, 2007 In college I made a pinhole camera that took whole 8x10 sheets of paper to use as "film". I went through some rough calculations to figure out the "ISO" of the paper and also what my aperture and focal distance was. Im sure there are resources around to help you with that. If you use Photo paper, you will have a negative image on it after you develop it. What i did was just scan the paper into a computer and reverse everything.

tripanfal Posted January 26, 2007 Share Posted January 26, 2007 You can use film or paper. Paper has a speed of about 6. You develop in a darkroom (paper) or a developing tank (film) Check out this forum here: pinhole images on paper will give you a negative, you can then contact print a positive. I have even heard of people putting paper negatives in an enlarger. http://www.photo.net/bboard/q-and-a?topic_id=2122&category=Pinhole or here: http://www.f295.org/ pinhole calculators: http://www.pinhole.cz/en/index.php http://pinhole.stanford.edu/phcalc.htm Google pinhole - about 4 jillion hits come up.

tripanfal Posted January 26, 2007 Share Posted January 26, 2007 He means scan the paper negative in Photoshop - invert to get the positive. Link to comment Share on other sites More sharing options...

You can do anything you want, that's the beauty of pinholing. Check out the pintoid site: http://www.merrillphoto.com/pintoids.htm http://www.merrillphoto.com/pintoidhowto.htm There is a lot of info on the web Link to comment Share on other sites More sharing options...

al_kaplan1 Posted January 26, 2007 Share Posted January 26, 2007 For best results use a fiber base smooth paper. Once it's completely washed you use a long squeegy to squeegy it emulsion to emulsion with a fresh sheet of enlarging paper. I use the overhead light in the darkroom to make the exposure. Peel apart the negative from the paper and develop the paper as usual. You can keep reusing the negative until it's about to fall apart. If you dry the negative you'll need to resoak it a bit before using it again. Link to comment Share on other sites More sharing options...
peterblaise Posted January 27, 2007 Share Posted January 27, 2007 . And for those casual readers NOT interested in building a camera or processing paper, those of us with interchangeable lens cameras can swap to a pinhole on our existing camera to become lens-free but use our current capture media (film or digital). http://www.google.com [pinhole lens cap] http://www.google.com/search?hl=en&sa=X&oi=spell&resnum=0&ct=result&cd=1&q=pinhole+lens+cap&spell=1 ... and have a tripod ready, as even in-camera anti-shake may not suffice for the time it takes for an appropriate exposure. But, hey, experiment. Remember, there are 2 kinds of cameras: - lensless / pinhole photography where everything is in equal (diffraction limited) focus, and - lens based photography where there is one plane of focus and all else falls off from there, sharpness wise. With all the ballyhoo about lenses, we sometimes forget the qualities of lensless photography. Have fun, play, and share some images! - Click!

chris_waller Posted January 27, 2007 Share Posted January 27, 2007 Look up a guy by the name of Justin Quinnell. He's based in the UK and uses anything up to garbage-bins mounted on wheels as pinhole cameras. Link to comment Share on other sites More sharing options...

lemastre Posted January 30, 2007 Share Posted January 30, 2007 I still have my chart of exposure times for various f stops (f/16 through f/1024) and EIs (6 through 400) that I'll be glad to send in PDF format. Link to comment Share on other sites More sharing options...
