> software has a bigger difference on the end result than the actual optics

Not everyone wants artificially manipulated photos that you can instantly upload to instagram without any post work. But, you do need good optics and sensor to capture good photos - the rest is post manipulation. Do you think RED or ARRI cameras cost $50k+ for their built in software? Nope, they don't actually have any of the "neural net" hype you've bought into from Apple's marketing. It's all done in post. Practically nothing you see in the movies or TV or Netflix or other professional broadcast is done on Apple toy cameras using their state of the art "neural engine" software. I haven't read about or seen any, but I reserve the right to be wrong so I said "practically."

Besides, you got to start somewhere and the camera interface would come before the splashy software built on top of it.

Just give me the RAW/flat log files (that contain the most information and dynamic range) and I will do the rest with a real editing program that cost almost as much as your phone itself, and look way better.

It’s not (just) marketing. You can try to “brute-force” your way up in image quality by increasing sensor size, better lens, etc, but there is a point where it gives you diminishing returns.

I’m not deeply familiar with high-end professional cameras, but low-mid pro cameras sort of slept for a long time while phone cameras had to play around the trivial upgrade route of bigger sensors and go the harder route to more intelligent sensors. There is a really interesting article about it that I may try to dig out, but there are such great tricks in modern phones like using the not that great lens stabilization to an advantage where minor movements of our hand will render the same physical position to several adjacent “colored” sensor positions and a clever NN can use this additional information to increase the lost sensors size inherent in colored picture taking. Also, HDR photos simply need intelligence.

All in all, in certain (rare) situations a newer iphone may very well shoot a much better photo than a DSLR camera no matter the comparatively tiny sensor size. Also, just think about the way the black hole was photographed - it also didn’t use an Earth-sized sensor, but the effect was similar if it have used one.

Your RAW/flat log files are also artificially manipulated too FYI and when you edit RAW, you just delay that artificial manipulation until you get to a computer.

Short of a 3CCD prism setup, most cameras use Bayer (or other) filters that capture a close but false image that then is reprocessed back to an approximation of the scene.

When people talk about smartphones having better processing, it just means on top of demosaicing, the software might be applying additional algorithms.

P.S. RED cameras don’t use 3CCD yet still cost $50k+ implying artificial manipulation is the way to go due to cost and physical limitations.
