Quick posting while the Covid-19 crisis is unfortunately still blocking all/most travel.
This year I came across Jay Vulture and his website and his fantastic B&W photos.
I would like to point you to his 23 part tutorial series. It is truly great. He shares in it his complete workflow and processing technique in the most thorough method I have seen so far compared with other online tutorials. Cannot recommend it enough. Plus you get the Photoshop file, where do you usually get those.
Also the recent London Workshop tutorial is great as you can watch him via the shoulder in the field and then during the processing.
Learned there again a lot, now we only need to be allowed to get out again.
