The third image in #153 shows both "sparkles" and "general glow", so nothing to do with the resolution of the imaging system.
Not at the level shown in your images. It was sometimes difficult to distinguish individual leaves on a whole tree photographed with a 56k camera but the blobs in your images are a lot bigger, and in any case the question is about quantisation of the radiation, not the image receptor!
We know for sure that electronic sensors are spatially quantized, although it isn't necessarily true that every pixel has the same size or sensitivity.Do you think it has no observable effect?

I also think that once you get an idea in your head no amount of evidence or logic can convince you otherwise.
The same applies to you too.

You seem to be the only one that thinks there is some sort of magical thing going on when it is pretty obvious we are just looking at reflections off of the water.So are you going to acknowledge that the 'sparkling water' is not an example of quantization? I think there is a possibility that if we pursue this for a couple of posts it could be resolved.
This sun sparkling water looks like a quantization of sunlight,

I guess you can call a video frame rate some sort of "quantisation", but it's a weird use of the idea.
Quantisation, sampling, digitisation and scintillation are not the same thing.

Read the second sentence of reply 173, which is explicit.
The effects from pixel size of the sensor is yet to be determined.
