Can I extend dynamic range by underexposing and then downsampling ("binning") my images?

In microscopy we often can sacrifice spatial resolution to collect more photons per pixel. Using sCMOS sensor and binning by factor of 2, we can get bump (up to 4x) in our signal-to-noise ratio (SNR). There is a bit of difference between CCD and CMOS here, but since all novel DSLRs I know use CMOS, it doesn’t matter.

Now question. Does taking underexposed picture (say, 1 stop: 1/60s instead of recommended 1/30s) with modern DSLR and binning (downsampling) image afterwards will give same result

I’m a beginner photographer and I want to buy a new camera, can anyone give me some suggestions on what to look for? [duplicate]

This question already has an answer here:

I have a Nikon Coolpix L810 (which I know is a very basic camera, but hey, I was just starting out and didn’t want anything too complicated.) Now I feel like this camera just isn’t doing it for me. I bought some ND lenses, a wide angle lens, and a telephoto lens, but those don’t improve the camera. I’m reading more and more about different aspects of photography and what makes a good photo (like changing aperture, ISO, and shutter

Is it possible to tether a Panasonic Lumix G3 with Lightroom or a tablet?

I have a Panasonic Lumix DMC-G3. I purchased it because it was rated the best for non-flash, low light photography, which is mostly what I do at libraries, historical societies, etc.

I saw someone using a tethered system at a state library, but didn’t have a chance to ask about it. However, I took a class at our local community college, to better learn how to use the camera, and was told that I could tether it to light room.

I recently tried it, with no luck, and from what I’ve read

Why is 18% grey considered to be in the middle for photography?

I heard someone (a photographer) say recently that 18% grey is half way between black and white, not 50%. This seemed a bit illogical to me, and when I asked her why, she said she didn’t know. After reading a few online articles, I found that 18% is often referred to as middle grey, and considered to be half way perceptually. Is 18% for some reason half way between black and white
