Here’s an easy way to make a quick lightbox if you have a round gooseneck lamp. It’s even easier than using a square light.
What makes it so easy is that a milk carton, rice dream or almond milk carton fits just right on the typical gooseneck lamp.
The steps are very similar to the square light.
1. Start by gluing aluminum foil on the the inside of the cleaned and dried carton.
Here’s what it looks like when you are finished:
2. Now slip the carton over the lamp:
3. Attach the sleeve to the lamp with some packing tape if it needs it, and it’s done! (The tape will need replacing now and then as the heat of the light will loosen it or melt it off. Packing tape lasts the longest.)
Yet Another Method
Here’s another way to make a quick lightbox if you have a round lampshade (example from EducateYourself.com)*
Measure or wrap paper around your lamp to get the exact circumference, plus add an inch or so for overlap. If your lampshade is fluted, you may need to have the edges of your posterboard fan out (similar to an A-line skirt).
Use cardboard stock or posterboard for your sleeve and cut to the correct size.
Punch some air holes on both ends (its important to get some ventilation so the lamp doesn’t overheat).
Glue the tube together. Paste a flap on top to give you something to pin the filter to.
Wait for the glue to dry and slip over lamp. Attach the filter with a clothespin or binder clip.
