@ Sabastious and Poppers,
Thank you for the nice remarks.
@Berengaria, how did you take that shot of the Falls
The picture was not so hard to get. It was taken from Glacier Point, a place that overlooks Yosemite Valley. (Beautiful view by the way; you can see the whole valley right below you, and all the main granite landmarks are about on your level. Half Dome is to your right, so close!)
The waterfall is across the valley, far away on the opposite wall. I heard somebody say 'Look at the rainbow on the falls'. I had to wait my turn to get to the rail for a clear view, then braced the camera against the rail to hold it steady...it was a long telephoto shot. The rainbow covered the bottom part of the falls.
The colorizing was done by experimenting in Photoshop.
Thank you for liking the photos!
