I haven't posted in this forum before but as I was going through some more china pictures from last year, I came across these 2 shots which I took in order to capture the same scene in very different ways. I hope these demonstrate the principles of the "exposure triangle" of adjusting shutter speed /aperture and iso.
(The scene itself is from the middle gorge of Yunnan Province's "Tiger Leaping Gorge" )
Both shots were taken with 5dmkII, gitzo tripod, CPL filter
#1 :
ISO 800, F5.0, 1/500 seconds
Adjusted iso and aperture to get the fast shutter speed to demonstrate the power of the water.
#2
ISO 50 , F22, 1 second
Adjusted iso and aperture to get slow shutter speed to demonstrate flow.
I hope that helps someone !
