...this took a few tries and some time in post.Photographing fog is hard...
Love the composition, of the second photo, Avondale!
Not in my books, but others may differ.Fog? Low clouds? Is there a difference?
Thanks for the compliments! I think the top picture may be an example of tree perspiration...I’ve heard that’s actually a thing.Not in my books, but others may differ.
Love those top two.
The way the mist clings along the ridge and just slightly rising from it in the top on is beautiful.
Overall composition are excellent.
I like the trees too. All very pleasing l
The usual definition is fog is low cloud which reaches the ground. The third image is an example of this, the middle probably not, and the first I think only along what seems like it might be the crest of a moraine at upper right.Fog? Low clouds? Is there a difference?
Perspiration is liquid secretion from sweat glands, which are specific to mammals. Assuming the intent was to refer to transpiration (outward transstomatal diffusion of water vapor in plants) I'm skeptical it's a significant humidity contribution in this case as that image is consistent with low evaporative demand. A more likely explanation is probably cooling of upslope flow.I think the top picture may be an example of tree perspiration.
Sounds like fog could be a matter of perspective then? In the first image, if I was standing on the hillside in the clouds, it would be fog? But since I took the image from a different vantage point it’s not? For example, the 3rd image I drove up into the mountains where there was fog...there wasn’t fog at the base of the mountain before I made my way up.The usual definition is fog is low cloud which reaches the ground.

Yeah, I meant transpiration...which to be fair describes essentially tree perspiration. I watched some nature show talking about it, and saw the images of mini clouds (for lack of a better term) hugging the trees in a way that reminds me of this photo. Certainly could be the upslope cooling flow you described though.Perspiration is liquid secretion from sweat glands, which are specific to mammals.

That "transpiration" is how you could collect water in a survival situation by attaching a ziploc bag over a bunch of branches with leaves (which needs to be bent so it aims downwards to collect the drips inside its own bag). After 1 hour you'll have some water in the bag.Well I didn’t mean to start a debate, but since I’ve stirred the pot...
