Water

If you've never been to Niagara Falls, there is a walkway going along the river area that gets pretty heavily sprayed by the Falls.

The mist is very fine and eventually you are totally drenched as you walk from the main bridge to America to the actual waterfalls area.

The Yashica wouldn't be harmed (no electronics) but I was curious how the spray on the lens would affect the pictures being taken.

Turns out, not so much, but in this false-coloured image you can see the spray pattern.
