Late Saturday afternoon I was photographing in Yosemite Valley when i saw a young photographer photographing Yosemite falls with a pop-up flash. I thought, do you have any idea how far your flash can reach? I thought I try to test my little Meike 320 walk-around flash. I removed the diffuser, set the lens to f3.5 and the ISO setting to 800. This is what I got. Not bad! Enjoy and keep on photographing!
