Anyone here tried this? I'm not really sure of the appeal of this yet. Here's the one I just made. I experiemented with hole size and the square piece of soda can sheet in this image had just the right size. Too big of a hole = too fuzzy. while too small = not enough light.

Here's two example pics below and what it looks like above. The pinhole pics were 5 second exposure at ISO 6400. Looks like I can see some dirt on my sensor. I'll need to do some outdoor stuff tomorrow when it is daylight.
