Natural Arch at Springbrook National Park New Photos
18-200 lens @ 18mm, f7.1, 1/30s, ISO 560
Thanks for the suggestions below. I went back on a showery/cloudy day and took some bracketing shots from 0.5EV to 2EV in 0.5 steps. I set the focus point just outside of the cave f8, @18mm, I'm not sure if this was the right thing to do here.
I ended up using only the -2EV shot and did some minor adjustments in elements. I could get more details on the ceiling but it looked odd in the dark area and this is what I believe is natural as possible. I was surprised there was not the same water flow as we have had a few nights of rain and the first shot no rain for about a month.
I goggled Natural Arch/Bridge and the falling water was blown out in all the shots I saw, even one taken by our local photo journo so I'm happy with the result.
No PP and -0.5EV
