Solargraph, County Wicklow
Six months in the making.
On last week’s Broadsheet on the Telly, Luke Brennan showed off his impressive solargraphy, a pinhole photographic method for recording the paths of the sun.
All you need is a bit of cardboard and a lot of patience.

For those interested I wrote up a post on the Solargraphy, which I think is the first time it
has been done in Ireland, the post is at link below. Enjoy…

Nice one, Luke. Very interesting.
Was it actually sunnier during winter than summer or is it darker at the top because of the angle of the light hitting the card?
That question was beyond my ken, but thankfully Austin was able to give me the brainy answer:
The simple answer is as your respondent suggested, that yes the summer trails are that much higher in the sky and consequently the path length behind the pinhole is longer. A more technical answer would be that oblique angles within the camera (as with summer sun trails) give a smaller aperture size plus a longer focal length. Off the top of my head that’s probably equivalent to two f/stops which would quarter the amount of light reaching the paper.
really nice
love how this stuff reminds us how small we are
Great write up on the link, very interesting. And a tip of the hat to your old man and his wonderful St Patrick statue. Great work, both of you.
You’re missing the point. A camera can be as simple as a beer can with a pinhole in it, and photographic paper inside. Albeit one you can feel safe leaving outside for 6 months. They’re very easy to make, and it’s a nice thing to do. You don’t need fancy gear to take great photos; this is a lovely example of this.
The darkening seems very sudden – I’m wondering if it’s down to the shape of the pinhole itself rather than the weather.
Looks like the Dublin Convention Centre.
