7x9in Pinhole camera test

I've had good luck with Ilford MGIV VC and Adorama brand VC paper. I think your camera has a flat "film plane" so some people might recommend glossy for better contact prints. I have not tried that myself so can't comment.

There is a choice between VC and graded paper too. I've only tried VC.

I think there was another thread on APUG recently about this.

Have fun!
