taking

This is my first critique on this site. I started taking pictures with my grandfather at 13 . Keep taking more!

Now the critique. I like the rainbow from the falls spray. Overall nice picture.I wonder how it would have looked with a longer shutter exposure to give the water a blur effect to show motion.

I think this is one of the better falls shots I've seen. The view from above, and the rock face is great. I actually like the shutter speed used here. I can see the details of the water, rather than just a blur.
