MANHATTAN – We had another heavy snow storm today – winter seems to be a never-ending phenomenon this year. I was feeling centered and symmetrical today. Images shot with my Sony A7rii converted to monochrome (by removing the camera’s Bayer filter).

WARREN CONNECTICUT – I experimented today with a “new” camera. I sent my several-years-old Sony a7rii to Monochrom Imaging for conversion to black and white only. This service removes the camera’s bayer filter layer; this coupled with converting the resulting files with software the does not run a de-mosaicing routine should approximately double the resolution of the sensor from the camera’s native 42 megs to a whooping 84 megs, way into medium format territory.
Key questions are whether the camera works properly after the change, whether the theoretical resolution increase is actually achieved, the impact on shadow detail and dynamic range, whether the best native Sony and Zeiss lenses are up to the increased resolution, and whether the sensor’s rendering of gray scale is attractive. I’ve can report positive impressions on all five questions – I’ll be shooting with this camera a lot over the coming months.
The barn below is a test image – I use the barn frequently to test resolution and other aspects of an image. As you can see the rendering is lovely. What can’t be conveyed on the web is the insane amount of detail captured. The other two images are from the same camera captured during a session on show shoes. Winter continues here.

NEW YORK NEW YORK – Some details from the street today: a Madonna, dirty snow (a major blight a week after a snowstorm) and some balloons. All shot with my Sony A7riii and a 55mm Zeiss Sonar lens.
Day 3010 of one photograph every day for the rest of my life.
On this date exactly two years ago (day 2,280): Another old lens: an antique Carl Zeiss Jena lenses 28 mm f8.0 Tessar from 1937 (the lens actually quotes its focal length in centimeters – 2.8 cm. This was amazingly wide for its time.
