    Since joining APUG, Ive had the pleasure of toiling through the site looking at all the great photos and ideas. But nothing has grabbed me more than the pinhole forum, I just had to modify a old polaroid800 to take 5x4 and convert it into a pinhole. Only been a couple of weeks but it has really got me excited about photography again (as opposed to take nice pictures with my Nikon D200). Haven't got the ability to post image yet but when i do.....

    Cheers

    I can't wait to see the pictures! Pinholing sure makes you look at packaged goods and other containers differently.
    And welcome, I'm a newbie too.

    Watch out! The urge to do ULF pinholes might hit you!

    The funnest pinhole camera I have seen was made from the body of an SX-70 polaroid camera...Open up the "shutter, close it, then hit the button and whoooose, out came the photo and we all gathered aound it to watch it develop!

    Thanks for reminding me...I have a 12x20-inch pinhole camera under construction. I cannot wait! Also, several Polaroids found in an abandoned house in the desert...

    I just found my hacked wide angle auto exposure pinhole polaroid. And, I have some of the new polaroid-oid film that fuji makes. Maybe tomorrow, or the next day if this thread is still going. I am feeling the need to do some self portraits. I need a new passport photo.

    I've been taking pictures for twenty years, but I think my most rewarding photo in the past nineteen years was the pinhole image I made during Pinhole Photography Day at the Rayko Photography Center in San Francisco. They had a pinhole camera made out of an old leather suitcase. I put a sheet of 16x20 printing paper in it and took it and my wife out under the freeway where we sat for thirty seconds. The resulting image was totally wild! I made a contact positive and it was wilder still! I really learned the virtue and excitement of working with such simple materials.

    I got to admit, i don't get the way you use paper and then make a contact print from it. Something else to learn

    Just like you would in making contact prints with film. You need a piece of heavy glass, or a contact print frame (or, if you really want to go the tech route, a vacuum table!). It sometimes helps to wet the paper negative and the new paper, and squeegee them together to eliminate air pockets and get better contact. You will need more exposure to compensate for the density of the paper base. Try it. It's easy.

    I think a pinhole passport photo is a GREAT idea. Or maybe wet plate? Something like as if Matthew Brady took your passport photo...

    How would you make a pinhole passport photo? IOW, how could you get the image that small, put the film really close to the pinhole?

    Or hold the camera at arm's length and measure the result, moving it this way or that until you could trim it out at the right size. You know, with passport, the size seems to be much more important than the image.

    I'm not going to do it tonight. I guess I better shoot one. I'll wear a funny hat, so the gov won't like it. I'll make a passport to some imaginary land!

    But why use paper not film, or is big (8x10 plus) paper a cheaper option then big film? Can u use the same paper for negative as positive.
    Can you recommend a decent book on pinhole that proberly the best option.....

    I can image you walking up to the passport control centre with a pinhole image ID photo, you will have to keep moving your head around to match the fuzzy image.

    I used a 16x20 sheet of photo paper in the camera because that's what was lying around at the time. It created a negative image, obviously. I then just sandwiched it with another sheet of the exact same paper under an enlarger and made a positive. If there was a sheet of 16x20 Tri-X lying around, I would have used that, believe me.

    The problem with self-portraits using paper negatives in pinhole cameras is the exposure time. I rate my paper negatives' "speed" at EI=3. I use Freestyle's Arista grade 2 RC paper for negatives; a 100-sheet box of 8" x 10" paper costs around $35us. In bright sunlight, a typical portrait may require 30-45 seconds exposure time. So you have the classic problem of keeping your head very still, and keeping your eyes open long enough to register detail. Also, paper, having a blue-only sensitivity, will render skin tones darker than normal, so you want to overexpose a bit to render a normal tone.

    You can contact print paper negatives just fine. I like to contact print onto a fiber based multigrade paper; this gives you a fine print quality, and the ability to adjust the print contrast as needed to adjust for problems with negative contrast. I use my condensor enlarger as a light source for contact printing. Heavy sheet of glass to sandwich the two sheets of paper together. I never contact wet the negatives wetted with water, always dry. And I never oil the backside of the negative, or try peeling the emulsion off the paper. I don't see the point; they print fine onto silver paper; perhaps alternative processes requiring UV light may need a more transparent negative, hence the alternative contact printing methods.

    It's been a long time, but I've been out of the country. Yes it is cheaper. Also, some people prefer longer exposures, so the slower time can be an advantage. Reciprocity departure is less a problem. Using vc paper is generally preferable to graded because it has green sensitivity (like orthochromatic) and can produce lower contrast because of that.

    Eyes are not a problem in the long exposure self portraits. Do you see a lack of clarity in the eyes in Daguerreotypes? That is because the blink is instantaneous, and the eyelid goes back to the same position -- enough for photography, anyway.

    The problem might be to get the gov to accept it. Of course, you could do it really large, then reduce it -- that provides a huge advantage. A pinhole image made on 8x10 with an ideally sized hole and reduced to say 4x5 will be MUCH sharper than a similar image made using a 4x5 with an ideally sized hole.

    Thank Bowazart, If I made a 8x10 pinhole to use VC paper, what iso for the paper would you give as a starting point. The plan in my head is to start using my existing 4x5 B&W negs to do some contact printing to work out the contact printing sides of thing, then maybe make a 8x10 or next paper up wide angle pinhole to do some landscape stuff. I like to build things.......helps me learn

    I haven't used paper in a camera for a very long time, but I've read comments suggesting that the useful ISO would be about 3. Must experiment. Yes, you can use the same paper. The best book is without doubt Eric Renner's Pinhole Photography: Rediscovering a historic technique
