Well, I'm back from a rather soggy Knockhill! It was pouring from just before the Sprint Race, and I didn't really manage to experiment with the aperture settings as it was so dull I needed as much light in the lens as possible.
Having taken a full spool of BTCC Cars, I went to rewind the film, when it snapped.
I think it's because I took one too many pictures!!!
I tried my best to get the film back in the spool under the cover of a bag, I'm going to ask the developers if anything can be salvaged, but I doubt it.
However, all was not lost and I proceded to take another spool in the Feature event, albeit not being able to experiment because of the weather conditions, again.
I shall see how bad they are on Tuesday!
