I just processed a roll of Fuji 800 which has both underexposed frames and overexposed frames. It should give me some idea of the difference in grain.
I was momentarily excited when I picked up the roll today because I thought I had captured a meteor. Then I realised it was lens flare. :( I checked with the lens when I got home, and yes, it was - it looked quite convincing for a while, though! All I have are star trails of the sky around Orion. Lots and LOTS of stars, but no meteors.... *sigh* At least I got to see them, even if I got none on film. Rob
