He would be a good teacher.

i have been contemplating pinhole photography for some time now after following this photographer for a few years.

I know next to nothing about photography, but I guess this has something to do with the ratio of the size of the aperture to focal length? Anyone care to explain in more detail?

That's why kids are encouraged to watch an eclipse using this method instead of looking up at the sun.

I believe it is more-so the size of the hole as compared to the wavelength of the light shining through.

Here's some info related to it:

this guy looks just like freddie mercury

Any aperture will produce this result, it's just that a larger aperture will produce a fuzzier image, so at one point it will just blur beyond recognition.
Basically every tiny detail in the image is spread out over the area of the shape of the apeture, but if you spread out the image over a large area you can get a pretty decent quality image.
The size of the image is determined by the ratio of the distance from the focal point to the sun and the wall respectively.
In this case the focal point is in the aperture itself but if your using a lens it can be elsewhere.

Diffraction only comes into play when you have a really tiny aperture.

A close-up of the image would have been nice.

Love this guy, and not just because he's *Canada-ian.
