",,,light doesn’t just sit around like a cabbage, it moves!"

All th

Capturing the Fastest Thing in the Universe

Observing light, Close encounters with Captain Photon, Shadows, Eclipses and invisible light beyond vision.


The Eye and Vision

The Evolutionary wonder of the Eye

Experiments with what we can see and how our brains work alongside our eyes to perceive: colour, stereo, perspective and time.


The Hole

A 500 million year exposure

Using a small hole to discover:the measurement of seasons, the microscopic world, eclipses and even using the holes in a cream cracker to capture a multiple inverted world.

The Lens

Camera Obscuras

How to create several effective camera obscuras from hand held perspective drawing devices to room sized projections using both pinholes and lenses.

Digital Projectors

How to adapt a hand held obscura to make a (not very good) digital projector for £1-00 that you can take camping.



Affordably allowing every student in your class to capture a 3-month exposure of the suns path across the sky. Science, art, recycling, STEM, ICT, astronomy, time, and history,,,,all for the price of a cup of tea!

and digital techniques

How to combine photographic materials with digital image capture using cameras, camera phones and scanners to avoid the use of chemicals.

Chemical Photography

Darkroom Construction

How to safely and affordably set up a temporary darkroom to open up learning opportunities in history, science, chemistry and creativity.

Pinhole Photography

How to enable a whole class to make and use simple but effective wide-angle pinhole cameras out of discarded materials to create traditional negative images.

and a CD Rom of Classroom resources and handouts!

Materials Pack

An additional pack of materials is available to accompany the experiments in the book here for £20 (+p+p)
Each pack will include materials to create your own room-sized obscura, three lenses (+1, +4, and +6)
for use in hand held and drawing obscuras, a readymade 6 month exposure camera and an emailed
PowerPoint presentation on pinhole photography and camera obscuras.

(As mentioned in 'Exploring Light', these items are easily available in some shops and online
but the pack is designed to save time in gathering some of the materials)
