Five Minute Introduction to Pinhole Photography

This short video is an introduction to pinhole photography. It talks about homemade and purchased pinhole cameras, the special properties of pinhole photographs, pinhole exposure, some artists who work with these cameras, and online resources.

Nice video. I just bought a pinhole "lens" for my dslr and I can't wait to learn how to use it. Greetings from Mexico.

Nice introduction!

You are cool, greetings from Ukraine!

Great video, I am starting into this and want to make portraits around 12*15 inches. How do you exactly change the negative photo in the paper to a positive in the dark room? that is what I wanna try. Greeting from Chile!

[@nancybreslin]

If you place a new sheet of photo paper face up, and press your negative against it face down (so they are "emulsion to emulsion") and keep them pressed together (by easel blades or with a sheet of glass), you can make a positive print. To determine exposure, you might first start with a strip of paper instead of a whole sheet ("test strip"), but be sure the paper goes in a place where each section with a different test exposure will include some highlight areas and some shadow areas.

Thanks for an awesome presentation.

+BurningtunaDC Thanks - I'm in DC, too. Nice to hear of local interest in pinhole photography.

[@tammymorin3164]

You are in DC! I must meet you one day.

[@nancybreslin]

Are you a pinhole photographer, Tammy?

[@rvargasphotography]

Nancy first of all I love your photographs but I was wondering if you would do a video on pinhole exposures a little more detail.

[@nancybreslin]

richard vargas Good idea, but it varies with your camera and the other equipment you have (I have an incident light meter, for instance, which makes it much easier).

Excelente introduction video
can you explain me better the calculation of the F number?
thanks!

[@nancybreslin]

+vmmunjin - For a regular camera lens, an aperture of f/4 means the focal length divided by four, so for a 50 mm (focal length) lens, the actual opening is 12.5 mm (50/4), while for a 100 mm lens the opening is 25 mm (100 divided by 4). Similar idea for a pinhole camera, but you use different information in the equation. If the pinhole diameter is .5 mm, and the focal length (distance from the hole to the film or paper, i.e. the diameter of the camera) is 200 mm, then the formula is focal length/?=opening, or 200/?=.5, so ? (the f#) is 400. (Very tiny indeed!)
