Waterfall tips....no problemo.....Spot meter somthing green in the area to get your base light reading....do either of your cameras have a spot meter? Then meter the brightest part of the falls.....compensate to the darker by about 1.5 - 2 stops and see how much diffrence is between the two......if it is quite close ...like 1/2 stop or less between the two after adjusting.....(usually so in softer light) you should be ok with the base reading off he green without bracketing. If you start to approach 1 stop or more....I would bracket shots later for a blend. Let the shadows fall where they may as your base exposure will capture most detail well.

Shoot in early morning....the shots I posted here recently, I hiked back in pitch black and waited for dawn light to fill the sky...but not put any direct light on the scene (still below the horizon) the same works for evening time...softer diffracted and even non direct light is best keeping the Dynamic Range in a reasonable and managable state.

Stomp around your scene...wear boots you know your gonna get wet...and bite pretty good on slippery rocks....and bring an extra pair of socks....if the hike isn't far back....just have an extra pair of shoes and socks in the vehicle....that way you can splash around and get the good shots....usually from IN the water.

Use a tripod religously....it is a must....no exceptions.....and use somtyhing like Expodisc to get your White Balance preset....the two biggest robbers of pop from your colors are improper exposure and improper white balance.

Use your day (brighter harsh light) from 10:00 or later to scout areas...and come back when light is prime.

Oh...and be careful!!!! It usually VERY slippery in falls areas.
