Standing in the river is sometimes the best way to get an image of it. When you stand on the bank you can take a picture of a river but stand in it and you can make an image out of being in it.
I was walking along the Merced River as it runs through Yosemite Valley. I could see El Capitan in the morning light. I had done some images from the bank but wanted something taken right from the middle of the water.
Normally, I do not like to haul the tripod out into a river bed barefoot, but the low river levels had left several gravel bars across it. A few big steps took me out into the river to a spot water flowed around me and I could really frame up the big rock right from the middle.
And my shoes were still dry.
