Nikon D850 monochrome: Pine Creek Peaks and Crescent Moon, Dusk
The Nikon D850 monochrome delivers jaw-dropping sharpness in a single frame along with dynamic range unrivalled by any other 35mm camera (as far as my eyes tell me)*.
What happens when ten frames (5 across, 2 high) are used to create a 280 megapixel stitched image? Very good things, as in a wall-sized image of extremely fine detail.
This image has a 5:4 aspect ratio, just like a 4X5 or 8X10 view camera. Ansel would have felt right at home. Its resolution is sufficient for a 61 X 54 inch print at 300 dpi.
Nikon D850 monochrome: Creating a Color Image from Monochrome Using Filters
Includes images up to a razor-sharp 280 megapixel size.
I’d like to make a 2 X 2 meter print of this image, but I don’t know if that can be done with quality in one piece. I might have to settle for 60 X 60 inches.
* With the color filter array of the Bayer matrix stripped away, all pixels see full light not the 1/2 or 1/3 or 1/4 the light each colored pixel would see, resulting in substantially reduced noise. Along with ISO 31 exposed with ideal ETTR technique and no debayering involved, the files are ultra clean and eye-poppingly detailed.
The Zeiss Milvus 85mm f/1.4 performs brilliantly on the Nikon D850 monochrome. In Pine Creek Peaks at Dusk, Crescent Moon, it was shot at f/4.5 with the B+W Dark Red 091 filter at dusk.
