I "exposed to the right" (at base ISO) to just barely clip the highlights of the clouds and spray, experimented with Luminance HDR to bring out the color and details in the gorge, which is necessarily in deep shadow when the sun is at the right angle for this rainbow, and finally adjusted the value curve to increase highlight contrast accentuating the details of the mist and separating it from the clouds overhead.

HDR can be tacky in excess, but it can also make ultra-wide pictures more realistic because one's eyes naturally adjust as one looks around a panorama: the rocks and plants in the foreground are very dark in a single picture straight out of the camera, but bright green and just shadowy in real life. The rapids wouldn't have stayed in place for multiple exposures so I had to take a single picture to stretch as far as possible.

The falls are very wet, very breezy, and very close to the rail on the Canadian side where I took this picture. Look closely in the churning water of the foreground for some soft spots from droplets on the front element :)
