For whoever what motion interpolation is also known as is the soap opera effect on movies and I agree, it looks terrible but most people don’t get it, it doesn’t bother them at all.

According to some neuroscience article that was posted in HN recently, some people might percieve reality in "less FPS." Not only that, but as people age, the speed also goes down. Most people I know cannot discern the difference between heavy motion interpolation and it being off. In the same way, I remember when people weren't able to discern between DVD and BluRay quality in 1080p displays. Even today, many people…

I did blind testing on myself and found out that I couldn’t see a difference between 72 and 144 FPS.

No free lunch, but an incredibly good value lunch. The quality that comes out of phone cameras is remarkable. And the times it messes up are so rare that it becomes a talking point worthy of hundreds of comments.

You guys are conflating 'adjusting light levels and sharness' with 'replacing whole objects in one area of scene with other objects from the scene' I think this particular big demonstrates a massive gap in what people think photoprocessing is, and what it has very recently become

It probably all goes into a black box ML model nowadays, so the model will conflate it if we don't.

I don't know about this - RAW files are recordings of sensor values. Those sensor values are accurate of what light the sensor measured. Then the sensor values are converted to a JPEG. So it's still an accurate rendition of the light - even though yes, it is a rendition of the light. But to completely replace some sensor values with some computer-generated values is a different ballgame, IMO. It's more akin to Photos…

This is really splitting hairs, but even our eyes are interpretation of reality. The camera sensor does not record the wavelengths of lights it is capturing, only RGB values. We can only reproduce the picture in a way that is convincing to our eyes, not what light what original being captured.

Yes, but still, as another poster put it, it's the difference of changing the lighting versus changing the texture pack...

I recently got a Pixel and was disappointed to see that the stock camera app has no way to control the focus manually. I guess Google is so impressed with their post-processing they think users won't need any control. Turns out, their software isn't that great at focusing in many of the photos I take, so I need a different camera app. My only requirements are: 1. Manual focus 2. Wide angle lens support I thought a re…

> Can anyone recommend a basic android camera? Preferably one that doesn't distort the world too much or replace faces with leaves.

Everyone's been complaining about the Fairphone not doing enough image processing and giving you basically the raw sensor output, making the pictures look bland compared to bigger-brand phones with worse sensors. So there's that option if you want a true-to-sensor picture and they also have a great open source community so you can also know what effects the camera app is applying.

Or install an open source camera on any android and at least that aspect of the picture-taking chain is covered.

If you want a terrible UX experience but reasonable amount of features, there's Open Camera: https://opencamera.org.uk/ | https://f-droid.org/en/packages/net.sourceforge.opencamera/

If you prefer better UX with just basic features (point and shoot, no knobs to turn), Simple Mobile Tools has an app for that: http://simplemobiletools.com/ | https://f-droid.org/en/packages/com.simplemobiletools.camera...

iPhones are definitely aimed at the more discerning, up-market customer. Android meanwhile is for the mass-market. iPhones have four levels of encryption designed to thwart the likes of the FBI trying to get data out of your confiscated phones. Androids have a checkbox tick that basically says "Encryption: Yes". iPhones have 1000-nit OLED HDR screens that are colour-managed and calibrated out of the box, and have Dol…

Don't group $50 device and $2000 device as "Android".

You can buy a $2000 Android loaded with crapware.

Yeah, even your eyes don't reproduce reality perfectly but at that point it's just semantics. He means he wants to see his daughter the same way through the camera that he sees her through his eyes, in real life, otherwise known to him as "reality". I don't think it's unreasonable to allow context of the statement to allow us to disregard "reality" as it pertains to quantum wave functions, in favor of something more…

The amount of post-processing your brain does to make you believe you see far more than you actually do in far higher resolution than you do, whilst combining two 2D views into a pseudo-3D view, is incredible.

That doesn't mean I want a camera to do it. With a bigger sensor I can get a nice crisp image, and that should be the target for what a phone makes.

> Those of us who have been shooting large digital cameras for the past decade and are some times sad that our photos often come out unsharp in poor light compared to smartphones can at least take some joy in this “no free lunch” demonstration. Can't replace sensor area with anything other than more sensor area. Week ago I got the perfect demo of that when I filmed a happening at around 10pm with only some dim garden…

With video you can’t “cheat”. You can’t gather up a second of frames and stack to one photo. That’s what phones to quite well. You only have 1/24s (say) to get the shot before you need to get the next one. I bet an Iphone12 would have made better stills than my aging canon 60D which I try to keep at 1600 or lower. And that’s pretty remarkable to be honest.

Oh yeah you definitely can. Multiframe mode on my old A7ii gets me all the way to 1/2 of a second handheld.

You have a 60D, which is very old, and it would still do much better than an iPhone 12 with a fast lens on top.
