Worldwide Pinhole Photography Day

Look at that, I took and posted a photo all in the same day. Like I said in the previous post, today is Worldwide Pinhole Photography Day. So here is my photo taken with the pinhole lens I made for my DSLR. Spring is slowly making its way to my part of the world, so I thought that a photo of new leaves on the trees would be appropriate.

Worldwide Pinhole Photography Day

Today is Worldwide Pinhole Photography Day! So I'm going to try to get out sometime today to and use the pinhole lens I made a while back, this will be the first time since then. I've been going through a dry spell photographically over the last little while, maybe this will get me going again. Hopefully I'll be able to get the photos from today up in a timely manner, my computer has been on the fritz lately. We'll see.

Pinhole "Lens"

The Pinhole camera or Camera obscura is the most primitive camera, invented about a thousand years ago. It was a simple device, basically a light-proof box, big enough to sit inside, with a small hole to let light enter and project an image onto the opposite wall. At first, recording of the image was done by manually tracing the projected image. A less manual method of recording was not discovered for another 600 years.

I made a pinhole "lens" for my modern camera. Although it's not really a lens, because it has no glass. I took the lens mount from my extension tubes and cut out a piece of cardboard to fit snugly inside. Then I got a pin and made a hole in the middle and attached it to my camera. The smaller the hole the clearer the picture. My first attempt at a hole was too big, the pictures were quite blurry. The cardboard was too thick to make a good, small, clean-cut hole all the way through, so I removed a larger piece of the cardboard and then covered the space with aluminum foil, since it's very thin and blocks 100% of light. Then, with the cardboard laying flat on a table, stuck the pin in again. This way I got a hole that was only the size of the tip of the pin. The pictures are still a bit blurry, but good enough, I guess. The depth of view seems to be infinite, there's never a need to worry about focus. Objects near and far look the same. Due to the small amount of light, all these pictures needed a 20 - 30 second exposure. Below is the first attempt:

I'm not really sure if there's any point to all this. It makes for an interesting effect, although, you could probably get the same effect by editing the picture afterwards. I just thought it was a cool experiment, it makes you think a little bit about how light and cameras work and how easy it is to take a picture now compared to long ago.

Here's some with the smaller hole. For some reason the dust on my sensor becomes very visible when using the the pinhole lens, not really sure why. I've never cleaned my camera since I got it 3 or 4 months ago. I should learn how to do that sometime.
