Never knew we had rules but I like both camera orientations for this scene. Neat to get such a nice sunset as a backdrop for these falls. I do like the color show at the top of the portrait version in your first image.
Welcome to the friendly skies Jim. It's quite amazing what happens when your photo viewpoints are no longer tethered to the earth beneath your feet. It can be a bit nerve-racking when you first fly out over water to shoot falls like these but once you see the results it's a lot of fun.
That's an impressive result for handheld and makes a strong case for using burst sequences and blending instead of lengthy exposures on a tripod. I would have shunned such an approach in my younger days in favor of lugging around my tripod but any more I am looking for ways to streamline the amount of kit I carry on trails.
Ken, I just love the blend of light and dark in this image - great capture!
One of my favorite falls in the deserts of Utah. A very popular hiking destination in that region.
That area below the falls is actually quite green most of the year since it doesn't get much sunlight down below the cliffs. I used to try out various shatter speeds and filters down on the little footbridge when foot traffic is low in mid winter.
These falls look like they deserve a name but then again if they had one more people might come. Neat view with the fall leaves poking out just beyond the falls.
In broad strokes you can think of the stacking step as a weighed mean.
Thanks for filling in the blanks on that count.
