Pinhole Day Questions

Friends,
I have taken a look at the current offering of this year's pinhole day
images. All are terrific! What a wonderful project!

I had a somewhat disappointing pinhole day, I am sad to say. I ran a very
small pinhole "workshop". (I use quotes, because it was really just a few of
my friends and I was only qualified to run this "workshop" because I had
made and used a pinhole camera and they had not, more or less.)

On Saturday we built our cameras. On Sunday we went out to shoot. As many
already know, it was VERY rainy in New York, but we were lucky enough to
step between the raindrops. We took pictures with oatmeal box cameras. Focal
length approx. 4"; pinhole approx. .0148" (#12 needle); therefore approx.
f/256 (rounded). We shot on Ilford Multigrade; approx. ISO 6?? An example
exposure was approx. 10 min under heavily overcast skies.

Here is the root of the question: All the negatives were black! I assume
that we drastically over-exposed the paper. I do not think that it was
fogged, but I suppose it is possible. The cameras were not light-leaky.

Does anyone have any clues? Luckily, we all took a turn with my pinhole
camera with Polaroid 669 film. Those were fine. But even so, I have a group
of disappointed Pinholers on my hands.

We will try again soon (obviously too late for this year's pinhole day and
too early for next year's) so any help is appreciated.

We did all have a great deal of fun, but it would have been nice to send
everyone home with their own photo, taken with their own camera.
