Scrutiny on a Bounty

Much Chocolate rewards for our Endeavour.
Having completed our Pinhole camera's, Keiron and I decided we had to try them out.
So we converted my shed in to a temporary Darkroom. (This was great fun all by itself)
And proceeded to ignore the instructions as proper engineers do.
When that worked perfectly, we converted our Negatives to positives.
When that didn't work, we resorted to that time old method of problem solving. We had a think, and having thunk, the solution came in a Blinding flash of the obvious.
We followed the instructions.
It all worked beautifully - Sort of.
