Quite often I need to use a light table for some illustration work. Using a light table can save a lot of time and paper, but most of them are bulky, expensive and difficult to assemble. If you don't have space in your office, a large budget and a lot of time on your hands keep reading... Here's my invention of the week (drum roll please...):
DIY LIGHT TABLE
Use a glass-oven dish as a base. Mine is almost A4. If your dish has a lid - use it, it's flatter and easier to use.
Set your phone on a "flashlight" setting and place it under the glass dish.
Place the photo you want to trace on top of the dish. You can use maskingtape to hold it in place.
Place a paper on top of the photo and trace it.
You can move the glass dish around to get a better light source.
