Thank you everyone for the very quick replies.
Mike - Thank you for your reply and advice about starting with a diluted paper or film developer. Seeing as I've only been involved with the film process for 16 weeks, I know almost absolutely nothing about the chemical side of it. Which is why just simply starting with a diluted film or paper developer would be easy for me.
Jim - Since I took the photo of the camera, I have painted the back black to reduce reflections and made some other improvements. I use a piece of a heavy duty black trash bag to cover the back when I'm shooting, held on with a rubber band. Seems to work pretty well.
ralnphot - Thank you for the simple answer.
JSebrof - I think the paper negatives that I was using have almost the same speed at the ortho litho film. I was getting exposure times of around 5-7 minutes in low contrast areas. Those exposure times add to the fun of pinhole photography!
Chazzy - I haven't been able to find anything that's cheaper than the ortho litho film. I'm on a pretty tight budget (being a college student and all). Besides, I'd really like to be able to load the film under a safe light and be able to develop by inspection.
Allen Friday - I'm not in that much of a hurry. The semester just ended for me which means that I won't have a darkroom available for me to use until the end of January when I go back. I'm very much looking forward to your results using the various developers. Thanks for the tip about the D76. I know for a fact that we have that available in the darkroom. Do you suppose they would have Rodinal for me to use, or is that pretty outdated?
