Why do some people shy away from high megapixel cameras/sensors

You don’t have to live near someone. Most of the remote meetings tools today allow a person to remotely work on your Mac for you while you watch and talk with the person.

Zoom is just one of these.

Yes! I had this done when I bought a new Mac Mini M1. It was awesome but it was a low end Mac and I decided I wanted to wait for a higher end version with more RAM. So after playing with it for a few days I wanted to do a clean installation of the OS and landed in a world of trouble. Now I’ve been on Macs since forever, late 80’s, and I can do a clean install in my dreams. But this one wouldn’t work, no matter all the tricks I pulled (turned out to be a bug which they fixed in a quick update). So I called them up and they were stumped too. The first guy couldn’t solve it, but the second said: I’ve been in computers for 20 years. This is a software bug and no software bug is going to beat me. He had to jump through a lot of hoops but he did solve the problem.

Anyway, as the Mac Mini was stuck at first and inaccessible, he first looked at the screen via my iPhone, that I had to hold up to the screen. Later, as we had control back over the Mac, we switched to direct remote control. He didn’t do anything himself, although he could have. Instead he pointed to where I needed to go. It was a weird sensation to suddenly not be alone on my computer! And all the while we were on the phone, talking. It worked miraculously well.

For the last year, our 29 employees and contractors have worked from home, and collaborated daily, sharing screenshots, files, and remote accessing when needed, while maintaining two week scrum sprints, and delivering software to production at the same time. No issues and more efficient than being in the office, IMO.

LOL. My wife is a scrum master for a major corporation, and for the last year she's been sitting at her desk beside mine in our home office talking about "two-week scrum sprints" and "delivering software to production."

Think one of the major issues with High Resolution Sensors is the extra motion blur you get, this often requires higher ISO to account for it. Reducing the quality.

Sharp is Sharp so most people won't need to print over the top sizes, I regularly print upto 36' x 24' with minimal sharpening from a 20.2mp sensor.. A Good lens is your friend if you want to print large

There is no more blur from the results of a 45Mpx sensor than there is from a 20Mpx sensor. The only effect you see is from your own desire to drill deeper into the digital content of the one file vs the other.

If you zoom deeper, the blur becomes more pronounced as would be expected, but this isn’t a disadvantage of a high resolution sensor.

Said another way, a wingtip moving across the frame has the same blur on two FF sensors with the same settings, regardless of resolution. You are the reason the higher resolution sensor looks to have more blur because you are zooming further into the image with the higher resolution.

This is what I do with my photos in the iMac...

You have your camera images and your final images well protected. Are you backing-up/protecting your image editing strokes?

Not the image image-editing strokes. The backups are just for everything on the computer (apps, files, and so on), just in case that the hard drive fails. On the Mac you can use Time Machine, but I also use Carbon Copy Cloner (CCC). Should the hard drive crash and I have to replace it, I can restore the new one from the one of the backups. Also, with CCC I can create a "clone" of the internal hard drive, so when I restore the new hard drive and then start the computer, the desktop and everything else is exactly as it was before the crash.

Exactly right.

Another way to explain this would be, "you are getting exactly the same motion blur, but your sensor is dividing that blur up into more pixels."


.


"Your" and "you're" are different words with completely different meanings - please use the correct one.
"They're", "their", and "there" are different words with completely different meanings - please use the correct one.
"Fare" and "fair" are different words with completely different meanings - please use the correct one. The proper expression is "moot point", NOT "mute point".

Totally true. The distance the object travelled across the frame within the space of the shutter speed is exactly the same absolute distance in either instance.

If you keep your "viewing geometry" the same, you won't see any difference.
