That might be good for myself, or if I’m honest even my wife, but my daughter looks perfect to me and I only want to see her in reality.

No imaging system reproduces reality. You're always getting a compromised result.

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 human. There's a large difference in something that's goal is to capture what the eye sees and something that's goal isn't. It feels like Apple thinks they know what's better for us than we do, which I admit it's perfectly capable of doing in certain scenarios. But, when Apples thoughts do not align or go directly against our wishes it's uncomfortable, it feels like your "reality" is being ripped from your hands in favor of what some giant corporation thinks your reality should be, for any large number of opaque or intentionally obscured reasons.

This brings new meaning to the old quote, "history is written by victors." Today, the victors are Apple, Google, etc., and they are writing their own version of history as its recorded...

They are the means, but the "victors" are people's vanity. If people didn't want blemish free pictures, they wouldn't be offered --but airbrushing was a thing and old fashioned paintings also tended to skip the blemishes --unlike mirrors. So, today, this continues albeit more perfect and automated for our consumption.

Bad vision airbrushes even mirrors. :-)

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…

> 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.

Correct me if I'm wrong but there's still a huge issue with silicon processing capabilities/power when it comes to image sensors (which is why camera sensors buffer images between shots). I unfortunately don't remember the context but it said something that it was (very far) from possible to actually get all the sensor data into the processor and as a result you only take a small fraction of the actual incident light/photos practically.

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.

It is not accurate to compare the capacity in Amp-hours because the Nikon EN-EL15C battery has twice the voltage (two Li-ion cells in series) of a single-cell smartphone battery.

As well I'd like to add the thought that the smart phone could be running all kinds of battery draining things in the background. So actual battery life depends not only mAh but how efficiently the device uses its capacity.

I hate how much phones lately alters the images. Of course it most of the time makes the images look better, and cameras are a big selling point on a phone. But I don't like how my photos of people suddenly have a filter applied to the faces, how a picture of leaves during fall have vibrance exaggerated, how the sky looks clearer than it really did.

Fully agree. My wife and I went out on a date about a month ago, and during it, she took a selfie of the two of us. There must have been some filter on by default because our faces looked perfectly lit, our skin completely blemish-free, no smile lines, etc. It was a great picture, but I remarked immediately that it didn't look real. And I don't want that -- it's not us but an idealized, optimized version of us. I sim…

I'm curious what model phone you have. In the past Samsung, Google Pixel, and Apple phones all had their own approaches to computational photography and would all take photos in their own "style". Samsung would priories for vibrancy and clear faces, Apple would try for "most correct" but often got quite flat photos, and the Pixel managed to do with a middleground.

Very much agree. I took RAW pictures with my Nikon on a christmas party, and even took the time to properly develop and adjust them. Still, people complained on how "old and bad" their faces looked (in pretty normal pics, nothing fancy). I attribute this to the fact that everybody is now used to phones completely editing faces and smoothing skin and adding saturation, etc., which makes us more "instagramable" althoug…

Just wait until the phones are automatically giving people cartoon character eyes...

I think the iPhone is doing this with the portrait mode. It may just be the smoothing or a bit of lens fish eye creating the illusion, but I swear that all the portrait photos of me and my family have slightly larger eyes than reality.

Half the time it's the camera, the other half, it's the display setting. Samsung phone has different modes for their AMOLED screens.

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…

Does Open Camera not show the switch multi-camera button on your phone? From https://opencamera.org.uk/help.html Switch multi-camera icon - This icon only shows on devices with more than one front and/or back cameras, and allows you to switch between those cameras. For example, a device might have two back cameras, one standard and one ultra-wide, this icon will switch between the standard and ultra-wide camera. If S…

Not the person you were replying to but I also have a Pixel 5 (still on Android 11). I didn't realize it until the previous comment but I also cannot access the wide angle camera. The button simply doesn't exist. Other 3rd party apps like Lightroom also couldn't find the 2nd camera. But a gcam mod finds it unsurprisingly.

To answer op's grievance though the wide angle is fixed focus, so they could use gcam for the wide angle and open camera for the regular lens.

I sometimes hang out on mountainbike forums. A user posts that despite a new chain and setting up their rear derailleur according to instructions gear-changes are clunky or the chain skips when applying power on the pedals. The usual reply from the forum members is then to send a photo of the cassette since excessive wear there leads to these problems. This used to clearly show that the user needed to replace their w…

I had a 12-speed cassette nearby so I photographed it several times (iPhone) and I can’t see any problems.

Is it possible you’re seeing compression artifacts from the forum software? Do you have an example?
