HI David,
I don't think that I have seen you around here much, before this week, so welcome!
(It is possible that you already participated in the past weeks, but I have been an "absentee landlord" recently, so please excuse me then.)
About your observation on gear used:
I think that a recent generation Iphone (mine is still an 11 and we are already at generation 14) are quite capable image makers (with fairly decent small lenses and making use of some extensive software trickery, no doubt).
On this hike, I also carried a small "real" camera in my shoulderbag and I have used it extensively with all three small lenses.
For such a hike in expected good light, I take the old Panasonic GM5 body (no IS, but it is the smallest interchangeable lens camera with a real viewfinder).
And for lenses, I take the Pany's kit lens 12-32 mm, then the small plastic but quite good Olympus 40-150mm lens to give me more telephoto options, and an Olympus 9-18mm lens for wider.
That gives satisfactory range and results in good light. I add a fast prime when I know it is gonna get darker or if I want shallower DOF (portraits).
(But none of it is weathersealed, so walking under a waterfall is a bit scary - I carry a waterproof backpack ...
but if the shot is too tempting, I WILL use the camera without swapping lenses. No accidents so far...)
The results from that camera are still on a hard disk and will join the long waiting queue for processing.
It will include an image very similar to the one above. When I see a truly great scene, I always double-shoot with camera AND phone.
When I get to them, they will yield better results and more options, being shot in RAW.
But that is the trouble with my "real" photography : it always still needs that post-processing.
The main benefit of the iphone (any smartphone) is its immediacy : images can get a quick touch-up and they are ready to be shown to the world.
I understand the appeal, although I also still keep my real cameras.
But gear, in the end, does not matter.
What matters is the image. That is also the philosophy of this thread.
Compared with literature, photography is about the novel, and not about the typewriter it was written on.
(Although I am nerd enough to enjoy talking about gear too, and I especially love the experiments some of our gang make with extraordinary equipment.
