> the amount of light on a given area on the sensor remains unchanged This isn't the only thing that matters. It also matters that you're amplifying the noise more by enlarging it 4x as much as you would have on the larger sens

I think you might be right. A lot of the damage already has been done... but the pro and prosumer camera markets are still shrinking pretty quickly. It's a concerning trend, which makes me hope that camera manufacturers get ahead of th

Well first of all, there are things that can be done in camera better than they can be done in post in any reasonable amount of time. Image stacking is one of those, since alignment even with the best software is spotty, and cameras could i

Yea. You can't beat the physics of big optics... but there ARE ways to get around some of the limitations of smaller optics. You can fake depth of field, use image stabilization and image stacking to gather more light with a smaller ap

I think it's important to bear in mind that the phone doesn't have to beat the full-frame camera at this game. It only needs to be "good enough". The fact that the phone is much more convenient to carry and use already

At the risk of sounding pedantic - the f-stop* roughly equates to "light per area" or brightness, so if you're using crop factor, you need to apply it to the f-stop as well as the focal length. So for a given full-frame lens

Most phones I've dealt with actually allow you to output raw image files. I'm not saying they have the same dynamic range as my A7iii, but they're not compressed or color-value limited like JPEG.

True, but there are going to be ways to make smartphone images sharper. You can already do some work in Lightroom to mostly bridge the gap. IMO professional camera manufacturers need to get ahead of that by putting computational photography

Unfortunately, camera manufacturers have been very slow to adopt computational photography techniques in professional grade bodies. We're just now starting to see things like image stacking (usually called "digital ND filter&quo

Retail establishments don't usually gouge nearly as deep as eBay sellers. Also, the free market is why price gouging exists. It's a natural consequence of supply and demand coupled with speculation. The only solution the free mark

Aren't all 3D computer games "simulated"? There must be a better adjective.

Humans can and are absorbing some of what the machine has demonstrated. I think Kasparov has it right when he says that the best player isn't a human or a machine, but a human using a machine as a tool. The machine can help the pla

They're quite similar to slide rules in that respect. Learning how to use one gives you an intuitive grasp of the operations you might otherwise miss (or not see as clearly), but there are far better tools for doing the actual computat

Play Commander (formerly EDH) with a deliberately casual group. There's a lot of variance in the games, variety in the cards, and weird interactions to work out. You can buy preconstructed commander decks for $35 (maybe a little more),

Forcing companies to internalize the environmental costs of spills and leaks would go a loooong way toward achieving the second goal. The problem is the people who write the rules benefit from political support of the very companies that ne

By "using a digital process", I mean altering the image rather than simply capturing it. However, every single camera phone I've ever had had PLENTY of computational photography built into it.

Computational photography is basically anything that uses a digital process for a chemical or optical technique. You don't need to be using non-standard optics or deep learning AI techniques. It can be as simple as averaging a bunch of

I was going to add C++ to the list, but I see that it's listed as cpp. It's lists c-- correctly, so I don't know why C++ would be any different.

That's insane, though. In reality, these things can coexist just fine, but even if they couldn't... why wouldn't you want to have a business model with lower overhead?

It's still a bit orwellian to manipulate students into installing a tracking app like that. Couldn't they just have the students who want to opt in swipe or tap their student IDs as they enter and again as they leave?
