This is an Instructable on how to build a small, effective spotlight that's ideal for stop-motion animations and photography.
You'll need very few ingredients and about 10-15 minutes of free time.
It's basically a cover that fits over your lamp and condenses it's usual wide-spread rays of light into a much smaller area.
Step 1: Ingredients
You will need the following items:
- A lamp (preferably one that's fairly flexible-poseable)
- Some masking/packing/clear tape
- A cereal box or other thin cardboard
- An empty kitchen/toilet roll tube (the longer the tube, the smaller the patch of light)
- A knife
- A drawing implement
Optional Extra: A circle cutter (Handy for the hole that the tube fits into)
-:IMPORTANT:- The bulb in your light MUST be energy saving. Regular bulbs will get too hot and you will risk setting things on fire.
I have used an energy saving bulb in mine for hours and barely even gets warm.
Step 2: Marking the cover.
This step is very simple. Place the shade of your lamp onto the cardboard and use your drawing implement to draw around the shade.
You should get a correctly sized circle!
Make sure you leave about 2 inches of card all the way round, you'll see why in the next step...
Step 3: Making the 'fringe' Pt. 1.
Remember leaving a 2 inch border?
Well, now we utilise that to mark another ring, 2 inches out from your original ring and then cut along that line. (The dotted line in the picture)
Don't worry, it doesn't have to be exact, a rough cut will do.
