Cape Neddick Lobster Pound. - Monochrome Sensor
« on: April 07, 2019, 06:16:39 pm »

Monochrome Sensor conversion means the CFA and Microlenses were removed from the sensor

Monochrome Sensor conversion means the CFA and Microlenses were plasma etched off the sensor

I like the first in particular. Do you really seen any significant difference between the stuff coming off the converted sensor and a good B&W conversion from a colour image?

the resolution increase may be subtle but is significant.. for this 36 Mpx sensor = 9 Mpx red + 9 Mpx blue + 16 Mpx green; anything in the image that is red benefits from the full 36 Mpx instead of 9 Mpx for example..

the sensitivity has been increased with the absence of the Color Filter Array (CFA), at least 1.5 to 2 stops.. but it feels like much more in bright light..

additionally the ICF was replaced with BG-38 glass so there is no AA filter at all.

Nice. They have a sort of 'mesotint' quality, which I like a lot.

Yes. It feels like it's leaning a little right, and this somehow contributes to the rusticity of the scene.

the greys subtleness is superior (than bayer sensors) already at these dimensions.....and I imagine the sharpness at higher dimensions.
Very good, and very good idea to remove that bayer mosaic (it has no future, at these days and more in the future there are very better
solutions for both colours and b/W).
All the best,

There are a thousand studies/photos there, just waiting to be captured in addition to the excellent series you’ve shared. Nicely done.

I think Bob may have meant Mezzotint...it's an intaglio form of print making. It has the ability to capture creamy rich blacks.

thank you.. yes.. I strive for that engraved effect.. some here consider it "crunchy" in my infrared images.

Two more from yesterday. Clouds were more interesting and the light enabled "extra crunchy".
