About the Image(s)
It was taken in March of 2015 with a Canon 40D and was originally a color photo.
It was converted to B&W, cropped to straighten the skyline, and contrast was added to try to highlight more of the lower portion of the shot.
I also add a degree of graininess which seemed to add to the clarity/distinctness of the bubble paths.
I like the way it became difficult to ⬓see⬠where the surface of the ice began vs the subsurface. The shot was taken near the ice caves east of Cornucopia, WI., and it was shot at
Tech: F/11 @1/1600 second with an ISO-800.

Mark, I find this to be an intriguing image. I looked at it for quite some time trying to figure out what I was actually looking at in the foreground especially. That is to say It held my interest. And my brain still can't reconcile it even after reading your description. It forms an abstract landscape with the overall lack of sharpness (was that on purpose or accidental??) and grain contributing to the moody, almost-other-worldly presentation.   Posted: 12/08/2023 09:49:23
Michael - It took me a while to figure out what was going on there even standing right on top of it. Evidently there are tiny air bubbles trapped under the ice that heat up just enough when the sun shines on them that they actually melt their way up through the ice causing these trails. This comes from a conversation with one of the Park Rangers who monitors the ice at the sea caves on Lake Superior   Posted: 12/08/2023 10:04:10
Amazing Landscape image ... like Michael, even after your prime description I was still perplexed ... but the subsequent articulation brings a bit more clarity, indeed.
However, on a technical note the overall focus (lack of clarity) in the foreground and the background is very odd considering it was registered at F/11 and at a very high shutter speed ... also, it does not look like camera shake, but it could be.
Another possibility, if you used Auto-focus, this would surly be a prime suspect, indeed. Can you add any thoughts about the, for all practical purposes, there is no apparent point of focus. Thanks, Mark.

Hi Mark
It sure is difficult to see where the sub-surface begins. Despite my best efforts, I still can't see it. Must be spectacular seeing it but very difficult to photograph.
