In my experience, RA4 paper requires a lot more light to make aything, and at that point, it's not much.

Only B&W papers work for this.

@ Peter de Groot :

I used ilford multigrade fiber paper, matte. It was all I had laying around open already.

The can is an oatmeal can I didn't so neatly cut open. Then I took some 120 black backing from a roll of 120 film, taped it on with black tape, punched a hole with a pencil. I forgot to flock it with black matte first, but that's why I got a "V" on my image, it reflected off the bottom of the can...

Here's my contribution, taken with a broken old 6x6 bellow camera converted to a pinhole camera.
Exposed for three days.

sweet. I haven't done much lately. Think I'll need to give it another try if the wheather gets better. Been cloudy here for the last two days. Thanks for the pic!

I suppose it is too hot in Memphis for this. I built a pair of pinholes with the absolute tiniest aperture I could make. Mounted them on top of a building for a couple months and let them expose. The result? A hole almost burned through my paper and the paper crinkled and discolored. I am going to rework my plan this fall and try some winter exposures.

Hi, here you can find more info about using pinhole cameras to record the paths of the Sun:
