Camera Obscura

This inspired me to convert my room to a camera obscura. For a long time, I was too lazy to actually do it. But I got bored yesterday, so I decided to put the idea to the test.

I improvised a pinhole using stuff lying around:

The result was pretty cool:

HA! That's awesome!

This is the very first photo I took with my first film obscura I made from a cellphone box.

Anyway, your room definitely qualifies for this:

The exact same technique you used for the photo above is just fine.
