Photography in the Ultraviolet spectrum

Step 2 Take your light bulb

and break it, once you've broken it, take a piece that will cover your camera lens and work out a mount. I used the same mounting technique from my previous instructable. Okay, I cheated and used a glass cutter.

Here it is already to mount on my digital camera.

'Nice touch' saves the cost of a filter but kills a black light bulb unless you have a friendly stage 'sparks' for duff ones. Two ways of getting most of a light bulb with out just shattering it #1 Remove the end cap and snap the stem ( Try this on some old household bulbs, first remember goggles & gloves! ) #2 Loop and tie a light string around the neck of the bulb (on the glass not the metal ) hold in a clamp around the bulb with neck/base vertical, run a small quantity of alcohol on to the string and with care light the string and stand clear ( Try this on some old household bulbs, first remember goggles & gloves! ) Note not all Blue UV bulbs have Woods glass as some "Fly killer " bulbs are just painted! Have fun
