I had to check that, as these big chunky camera batteries “feel” like they should have a lot of mAH compared to a phone. And I am wrong. Depending on the phone. A Nikon battery: 2280 mAh. An iPhone 13: anywhere from 2406–4352 mAH. Yeah, that’s a way smaller power budget than a Pro iPhone, especially as you have autofocus and image stabilization systems that have to move around a lot more mass.

Keep in mind that my Nikon really only consumes power when it's _doing_ something. I can leave my camera "on" for months at a time and come back to a fully charged battery. The screen is off except when I'm previewing a photo. The viewfinder is physical. The metering is only on for 10-20 seconds after I wake the camera by touching the shutter release and is only displaying on a low power monochromatic LCD. Autofocus…

That comparison doesn’t work for newer mirrorless cameras. I have a DSLR and mirrorless strapped to my body at each wedding and I go through more than twice the amount of batteries in the mirrorless.

They also take a second or so to wake from standby which is super annoying for my job, so I have it set to 5 minutes. That essentially means it never goes in to standby on a wedding day.

This is so common in consumer tech. Is there a name for it? Like how any new TV has horrible motion interpolation and sharpening enabled by default, or the bassiness of Bose/Beats headphones.

Taste. It takes time and experience to develop, and the masses on average don't have it. As in, they might have developed taste for a few products, but not most products. Hence, the mass-market products are aimed at people with no taste, because that captures the largest slice of the consumers. Random examples: - In A/B tests, the typical personal will rate louder music as better. Hence, all bars and pubs turn their…

It's even worse with Harley-Davidson motorcycles. They're not just going for low and loud, they have a specific profile that they tune their engines for. It will be interesting to see what they do if they ever make an electric.

As far as I understand the goal of using ML augmentation in camera phones is to capture what the eye sees. It's to compensate for the limitations of the hardware which on its own is not able to produce a true-to-eye result. You seem to be implying that the goal is to improve the photo to be better than reality but I don't think that's the case.

Right, but it can only guess at what the eye sees when hardware limitations don't allow it to capture enough information. Maybe most of the time it guesses right, but it's still a guess, and it appears sometimes it guesses wrong. Really wrong.

If it's combining information from multiple shots or multiple camera sensors, isn't that more like sensor fusion than "guessing"? I think calling it guessing is an uncharitable interpretation of what's happening.

Film development is actually quite a bit more subjective. There's a much larger variance in film type, and the chemical process. Perhaps it's harder to doctor, but it's also not necessarily truer either. With regards to sensor size and detail recorded...well that depends. Are you assuming 35mm sensors? Because people shot 8mm and 16mm too back in the day. That's not far off from smaller sensors today. Are we also acc…

Sensitivity of digital is amazing. You cant really get past ISO 400 on film without large compromises. But, as for size, photo cameras sporting film smaller than 35 were rare. Yes Kodak had the advantax (?) system and some other weird cameras here and there, but the vast majority of consumer pictures were taken on 35mm. As to the subjectivity of film, as I mentioned in the other post, most of the subjectivity came fr…

Specifically, this thread originated with the Kyle Rittenhouse trial which would be video. So for the average person, it would be 8/16mm.

Even for stills, 110/126 was very common.

As for your last point, it only ensured privacy from the poor. Privacy was always invaded by those with means like paparazzi.

There's also the flip side that the prevalence of digital has let people capture pivotal moments they wouldn't have been able to otherwise, including generation defining moments like the murder of George Floyd.

There was an update -- sounds like a leaf was really in the shot: > Big news! I sent @sdw the original image. He theorized a leaf from a foreground tree obscured the face. I didn’t think anything was in view, and the closest tree is a Japanese Maple (smaller leaves). But he’s right! Here’s a video I just shot, showing the parallax. Wow!

LOL amazing that the explanation was so simple!

> the problem is when light is not perfect, that's when the bigger lens/sensor are worth it even for a beginner that doesn't know much about photography. I think the opposite is true, from my (amateur) experience. It's much harder to get a good photo in poor light with a dedicated camera if you don't know what you're doing than it is to get a good photo with a smartphone. In good light, the better sensors shine throu…

Snapping good low light photos really comes down to how fast your lens is (smaller f stop number). A lot of kit lens (the ones sold with cameras, even nice cameras), are surprisingly low quality lens, and don't really open up much. My Sony A7-3 came with a kit lens that opens up to F3.5. This summer I purchased the 24mm GM F1.4 and WOW does it take fantastic night photos. No tripod needed, it lets in enough light tha…

f1.4 on a tiny sensor does not equal f1.4 on a FF sensor.... that's why they have to use "AI" to fake the bokeh. Yea a f1.2 might be nice but you would have to be really skilled to get stuff in focus wit that razor thin dof.

I wish this could be pinned to the top. Perhaps a follow-up post to HN would be worthwhile.

So many people will leave this thread incorrectly believing this was an iPhone problem. It could easily become the data point people use to cast doubt on all pictures they don't like.

Nothing at all. It’s honestly surprising that it’s not a bigger thing. Guessing what stops you is that the Apple team that makes camera software has a budget that makes the Nikon pc app team look quite small.

Cameras don't have DoF sensors which I believe the phone uses in its processing to know if there's a subject in frame.

they have that dof sensor so they can emulate dof, we get real dof.

In theory what prevents me from using a huge lens and sensor on a DSLR or a mirrorless camera and then using the same advanced software but now running on a desktop computer or a server that is many times more powerful than a smartphone to do advanced post processing?

It's important to note that recent iPhones contain the same M1 chip as last year's MacBooks. They are not limited by processing power. DSLR and mirrorless cameras have better optical properties. But they are held back by starting too late and being much worse when it comes to software. These cameras also are limited by their CPUs, which are a decade behind, and by their batteries, which are much smaller but expected…

held back? why on earth would anyone want the camera to do more then just give you a raw image file back? if you don't want to be creative then yea i guess go with a phone and let it make all the choices for you.
