The Moving Sun
This photograph is a
six-month exposure of Glasgow Science Centre taken
with a pinhole camera from the opposite bank of the river Clyde. The
home-made pinhole camera was positioned with its shutter open for six
months - from 21 Dec 2003 (winter solstice) to 21 Jun 2004 (summer
solstice).
The Sun's slow path across the sky above the science centre is beautifully
captured in this unique image. Note how the Sun's altitude (height)
increases progressively from December through to June, reaching its
peak in midsummer on June 21st. The missing trails
are due to the Sun being obscured on overcast
days. One outstanding feature of this photograph are
the reflections captured in the water.
The term "pinhole camera" was coined by Scottish scientist Sir David
Brewster, who was one of the first to make pinhole photographs in the
1850s. Pinhole photography is lensless photography. A tiny hole
replaces the lens, and as light passes through the
hole, an image is formed on the film at the back
of the camera. Pinhole images are softer and less sharp
than pictures made with a lens - yet pinhole images have a nearly
infinite depth of field.
