Re Eduards posted picture. It says NO EDITS, so I will just comment. The levels (white point and black point) are naturally done, proper for many things, but here, the sun is sort of a specular highlight, it has no detail, and could be clipped more. The key for B&W is to create ample contrast, specifically to have some very black areas and some very white areas. It was Ansel Adams best advice. I'd move the White Point down to where the water begins, about 200 level (clipping the sun, who cares? It helps the water.) Clipping color can change the colors, but this is B&W, little concern except for clipped detail.
Blacker blacks and whiter whites is contrast (opposite of flat).
I haven't done much B&W conversion - except for developing and printing in a lab back in the day while in the USAF. This is exactly the kind of feedback I was hoping for - thank you!
