Your room transforms into a pinhole camera in minutes. #pinhole #camera #obscura #DIY #how_to_make

A method for making the pinhole camera obscura room under 20$. 1) Make your room dark with black tarpaulin (approx. 10$) and curing/masking tape (3〜10$). (black one is better than clear one) 2) Make the window for attaching the pinhole (φ2cm) screen. 3) Attach it. That's it. Appendix “Consideration for the diameter of the holes....” The larger the diameter of pinhole is, the brighter and more blurred the image is. The smaller the diameter is, the darker and more clearly the image is. At first I recommend the moderate-size circlar hole (φ 2 cm). “Considerate of the position of a hole” If you make a hole on the upper side, you can see the upper of outside. If you make a hole on the lower side, you can see the lower of outside.
