Very good saturation of color. This is something I am still trying to master, rainbow that is, to get good color. I have been more successful lately. Good luck. You had a nice point of view for this.
great scenic capture and unique to see an actual rainbow. i like the haziness in upper background indicating water mist from the falls....somehow i wish the crowd of people were'nt there, but they do provide a sense of scale--great shot!
