As the original population size — i.e. the number of photojournalists on the planet — is...

An index mark used to align the lens hood when mounting it on the lens, possibly ?

No, the SEL1635Z's entrance pupil at 16mm is significantly behind that "red dot". And no, I won't tell you where it is, as it's quite easy to determine its position by yourself. I believe in the ...

If, after throwing a coin 79 times, you got 50 "heads", there would be a high probability that the coin is not fair / equiprobable.

With the case at hand, the reasonable conclusion is that...

Suppose the null hypothesis is that the occurence of Canon and Nikon...

The wise person thus chooses to spend his "photo-related time" visiting gear-oriented sites like DPReview, as it's well-established that there's no correlation between the gear used and...

"... always push to learn more."

A foundational philosophical teaching is the "γνῶθι σεαυτόν" (know thyself) principle.

In the D-K graph, the straight line (in dark grey) is what one could call...

One way to test the effect of D-K on D-K itself is to have an Internet forum permeated with the D-K effect discuss the D-K effect.

It's like General Relativity: spacetime tells matter how to move;...

Compact, certainly. As for "lower-quality optics", that kind of blather makes even more obvious that you're a...

Nope.

Suppose, for the sake of argument, that we're talking not about photography skills, but about logical thinking ability.

A significant number of people with mediocre logical...

The Commlite CM-ENF-E1 PRO adapter now seems able to control the electronic diaphragm of Nikon's E lenses. This video shows the electronic diaphragm of a Nikon PC-E 24mm being controlled with the ...

A rectilinear lens, even an ultra-wide like this one , should image all the bricks of a brick wall at the same size, hopefully with only minimal stretching (pincushion distortion) or compression ...

Indeed. The cos^4 relation takes into account all the "natural" factors that will lead, with a rectilinear lens, to vignetting as we move away from the image center. For example, if an object point ...

Still, there's the physical fact that components on an image sensor generate white noise and 1/f noise, and that sensors might contain programmable gain amplifiers, which means that the spectral ...

But isn't that approx. 13EV to 14EV lower than the pixel's saturation value, if the DR measurements for the A7iii published e.g. by Bill Claff are to be believed ?

Column ADCs convert the pixels of their column sequentially. A pixel column — i.e. a spatial arrangement — necessarily implies the existence of a corresponding temporal signal — i.e. the voltage ...

Indeed, but let's keep in mind that we're probably talking about the minute spectrum analysis of microscopic levels of noise seen in the mostly dark shot of the back of a body cap.

MOSFETs have 1/f noise. I wouldn't be surprised if there's a LPF — a simple RC network might suffice — at the input of each column ADC.
