The amazing art of pinhole solargraphy

Caught this on www.spaceweather.com... and thought I would share.

With and empty beercan (pinhole-photography)I took a picture of the Sun with an exposuretime of nearly 6 months. See the result. It is callled Solargraphy. Put a piece of photographic paper in an empty tin, seal it and make a pinhole of around 0,5 mm in it and fix it firmly pointing south towards the Sun.

What a fantastic way to document the change in seasons and inclination of the sun.

Some more:

That's beautiful to me!

I had to show my GF... she's a photographer.

S&F!

those pics make me feel kinda stupid for never really noticing how the sun moves. its obvious i know but i dont think many really give it a thought.
cool and slightly eerie pics.

Yeah it's a good way to put it into perspective.

Or actually, how the earth wobbles on it's axis over the seasons.

Amazing hobby thing to do, I will give this a try sometime.

So simple an idea for such a great result!

I think "wobble" is the wrong word to use.

Wobble, to many suggests the theory that the earth wobbles as it spins, like a jerky movement, these pictures show otherwise, they show a gentle motion.

Good point actually, But you know what I mean

You should, you observe it for a living!!

But you'd be amazed how many people are unaware of the way the earth rotates in view of the sun - why the poles spend months in near darkness or twillight.

I think these images show exactly that - just from a limited perspective.

I'm definitely going to do that down here in WA sometime.. tho with todays heat, I rekon it'd burn the photosensitive paper in a beercan. damn its hot...

Yeah I knew what you meant, others may not is all.

You may have to wait till June to do it, for the cooler weather.

Then you could catch the winter solstice through to summer solstice.

Oh and I won't tell you about the air-con I got for xmas then...

Hahaha Bugger !! I just walked out the back and it was sooooo cool, then came back in here and it's like a sauna.

I will have to learn the art of living with water evaporative systems in the heat, one day.. till then, they feel good at first..

Oo

Thanks for making this post. Very awesome perspective, I wonder what causes the unique patterns in the lines. If it is the tin, then I wonder if the tin was altered it could create different designs.

If I've read correctly it would be clouds creating the patterns.

Cloud passes in between the sun and the can and you get a blank spot.

Here's some simple instructions I found on making a pinhole camera:

Not quite the same as the can method but similar.

That is a pretty kick a** thing to do. Congrats and thanks for sharing...
