I wonder if it's a focal length, or this specific implementation a cause.

-
I can only hope it was automated... I wonder if use of an iq4 150 + lots of averaging would significantly impact your result.
-
Jim, do you use any form of multiexposure (i.e. frame averaging, etc)?
-
Better equipment may inspire psychologically and/or technically to do more shots in more diverse settings. There's a chance of skill' substitution, but more experience is generally better than less. ...

Jim, I agree there's plenty of green, that's why I mentioned only the red being low. Getting back to the original problem - it's just an unlikely for most of images to have very low 2 channels out ...
-
One came to my mind, but it is the one mostly lacking red. Those lights are sure not typical indoor lights, but also not lasers.
-
Jim, I can't possibly require anything from you, a fellow forum reader who shares awesome insight into technical side of imaging. I thought gb channels would be nearly zeroed, but apparently I'm ...
-
The purpose was to see if there's a difference between predominantly r channel vs rgb. If levels of gb are high enough, demosaicing will still use them to reconstruct the pattern, just with extra ...
-
Jim, Re red chart: fascinating. Any chance you could check if g/b channels were dark enough? Regards, Mikhail
-
Jim, Sounds good, thanks for the examples.
-
Jim, Nope, my interest in theoretical side of image acquiring and processing not as high. Thanks for your work.
-
BTW. Have you ever tried to take a picture of pseudorandom noise pattern at around pixels resolution and demosaic it?
-
Jim, If one takes a picture of a saturated red flower, cfa raw file will have 3/4 of photosights having very low signal. Hence, it would be impossible/hard to expoit correlation between r/g/b ...
-
I'm referring to a substantial lack of signal for 2 out of 3 channels, when pattern is highly monochromatic. Not to wavelength-aperture effects. Aperture is, but sampling density is not, as there ...
-
Unless a red or blue fine pattern being photographed. Green pattern to a lesser extent. Unless high iso noise overruns resolution of the cfa equipped sensor, but not yet the achromatic one. Mikhail

Price difference between r5 and r6 should be considered within a context of needed lenses and accessories. Plus, possibly, other expenses. Respectfully, Mikhail
-
Defishing a fish-eye image might be an interesting option. Given a real estate and resolution of a 44x33 sensor and fairly sharp fisheye lenses it might be worth it. I've been impressed so far, ...
-
About 30k, for a certified used one. But... a few more for an xf or xt body. Probably a lens too, unless one is going to use older or off system lens. Mikhail
-
The problem at hand is late arrival of Sony, with its cmos sensors, to mfb scene. Price-wise more or less reasonable high res backs are 80mp ccd, but we have been spoiled by cmos for many, many ...
