This is a fourth set of images from Pine Creek in Zion. I kept returning to this location all autumn and Winter. This is something a little different.

There are numerous waterfalls and cascades along Pine Creek. The above image is walking upstream from a large parking area right before you head up to to the Mt. Carmel tunnel.
In one of the pools beneath a tiny waterfall large bubbles formed. I spent 20 minutes taking images. You can see rocks in the creek bed in the two larger bubbles. The yellow highlights are late afternoon sun reflected in the water.
The lead image is an crop of the next image. The water was moving very rapidly and long exposures looked like a blurry mess.
I used a 100-400 mm lens at 400 mm to isolated the bubbles. A high ISO of 2500 stopped most of the motion at 1/45 second to get this effect. I played around with various shutter speeds to get the effect I wanted. Even at F13 there is not a lot of depth of field.
Here is a larger view of the same bubbles.

Yes it’s pretty. Fractal even. But could it be a fancy cover up for the inability to take a picture of real water?
I wanted to capture the bubbles. Long exposures blurred them.
1/45 of a second was trial and error.
We can work back to what I tried initially. I usually use ISO 100.
100-200-400-800-1600-3200 is 5 stops. So 2500 is opening up ~4.5 stops.
1/45 second (lets call that 1/60 second for ease in numbers.
Five stops is 1/30 1/15 1/8 1/4 1/2 seconds
At ISO 100, I would have been shooting between 1/4 and 1/2 second. I did not like that result.
I put on a strong 6X ND filter (1-2-4-8-16-32) and got to 20-30 seconds and liked the result even less.
It was trial and error upping the ISO to 800, 1600, and then 2500 to get the result that I did.
It’s refreshing to see abstract images of nature. I would think that a lower ISO would not work for this. I think there is sufficient areas of sharpness so the whole image is not blurry.
