Is Poisson Noise (“Shot Noise”) a significant source of noise for typical photography?
In this answer, @jrista states that even a camera with a perfect, noiseless sensor would still have noise due to "Poisson noise" aka "Photon Shot Noise" - noise caused by the random variations of ...

What is so special about ISO 1600?
I have heard many times that to minimize noise, the highest ISO you want to use is ISO 1600, and that no matter what camera or sensor you use, once you have passed this (ISO 1600) threshold, the noise ...

what's the relation between sensor size and image quality (noise, dynamic range)?
I'm reading this description on sensor size:
Digital compact cameras have substantially smaller sensors offering a
similar number of pixels. As a consequence, the pixels are much
smaller, ...

Why are sensors less sensitive to blue light?
This is a followup question to Why is the blue channel the noisiest?. The simple answer to that question is that sensors are less sensitive to blue, and therefore require more amplification, which ...
