Dark Box Diagram
Grey box built from black foamcore board, taped together. Ensure all "corner joints" are light-proof/don't let light leak in at the seams.
White slit has white paper (taped to outside of box) to diffuse the light going inside.
Front of box is open to camera; my camera is quite close to the edge of the box, and I drape a black towel over it all, to "close up" the front opening, avoiding any "front reflections" on the glass.
Results are longish exposures (2 - 20 seconds, depending on how big the side-light-slit is, how close the lamp is, etc.)
