Superb work, Davidwozhere , truly magnificent studies and informative as to how they were achieved 👍

Fungus inside one of you're many lenses

I think that it would be better if it was just a variable built in ND filter and not graduated
Something like 3 stops to 16 stops range for tripod use
I have that on my old compact Lumix LX 7 and its fantastic.
Just my tuppence, I would probably buy that version

Nice set Longtime of B@Ws, that last photograph in this session is sensational I think imho. maybe needs a tad more in contrast and definition but Jayus reshoot that scene if possible. Loads of potential, well done

BTW saw your colour ones Just after as well, Top marks

Excellent work Spad and commitment, considering the the sky's constant haze.
The second Photograph is wonderful

Super result Loadof, encompassing the grand scale , wait until you get used to it and one will instinctively know when to employ these techniques. I will have ago myself when time allows

One can also use this technique on closer foreground compositions as well. So plenty of uses

The strange thing Loadof is that I prefer the first one
Panorama software can also be used in a two shot sequence with the 50mm and should stitch perfectly without too much movement or wind etc, One will end up with a 6x7 look.
Try it

I meant to add Loadof ,to try this technique on a 50mm prime as they are almost distortion free.

Nice result all the same Loadof,
From my brief researching sometime back, is that professionals as well as ammeters put the camera on a tripod in the portrait position absolutely level in both axis and then proceed to take maybe 6 shots or more with a third overlap in each frame.
The reason for the vertical position it allows more latitude in height for the stitching to align.
You can also do this handheld with maybe 3 frames for a wide angle feel without the curvature
I will be trying handheld first myself and see what I can come up with.
Best of luck Flan

Very impressive and immersive, the lighting and exposures all handled immaculate.
