Okay, here's something else you can try... it's a little complicated, but:
First, go to the Black Cat Photo Systems site and find the "scene letter" of the type of thing you're going to photograph. It's divided into pages; "Fairs, amusement parks and rides" are on page 4, and the magic letter is K.
Il Linkus Clickatus
With your magic letter in hand (or in head) you can go to
this page, whereupon entering your magic letter and film speed in a Javascript gizmo will suggest an exposure for you.
Example: Magic letter K and ISO speed of 100 with an f/2 lens suggests a shutter speed of 1/15 for good exposure.
Obviously, Black Cat doesn't want to make this TOO easy, since they sell a dial-type calculator that gives you this information without having to leap about all over the Internet. If you think you're going to remain permanently allergic to exposure meters, you probably should contemplate getting one. (Although at $19.95 it may be
more expensive than a decent used meter!)
