One thing that I had to get through my head when I was learning photography was that there's no such thing as "no filter". Every image you take is an interpretation of the scene, either through digital signal processing or film chemistry or retouching.

When I spend time editing photos my dad would claim I was "lying" by editing them, he thought any modification to digital photos was wrong because the jpeg the camera produces is "reality."

But of course, as this article shows, the camera is adding its own interpretation to the scene. Since our eyes can adjust to many lighting situations, the camera has to try to compensate and reproduce what it thinks our eyes would see, but it has no way to know if it's right! So, sometimes it's necessary to go back to the raw data and recreate the image as you remember it, along with whatever emotions you want it to elicit, rather than taking what comes out of the camera as "gospel".

This is the dark side of "smart" devices that replace high-quality physical sensors with clever algorithms. When something weird happens, they might misbehave in the most bizarre fashion. The general pattern will hold for AI. If you give too much control over things to software that you don't really understand or control, it will behave unpredictably when you need it the most and there might not be a way to correct or override it.

> This was a moment for my Canon to prove that, despite its bulk, it can't always be replaced by a smartphone. Such a naive statement. Once those phones' white balance is corrected, they should be able to capture the orange tinge. Even in a DSLR, if the white balance is set to auto, it would not capture the orange tinge. Cloudy might be a good starting point.

How would I do this on iOS, if I had just my phone and no CaptureOne on a laptop or the like? Are there apps that let me use a gray card to set the white balance of raw photos?

When you click Edit on a photo, you will have bunch of edit options. Warmth and Tint sliders represent white balance. You can increase the warmth until it matches what your eye perceives.

Essentially you are telling your camera post capture what the temperature of the source is.

Your statement is also naive. White balance set in camera does not affect the raw capture. Only how it’s represented.

Smartphones have tiny lenses. As great as they are, a tiny lens has more distortion than the bigger lens of a dedicated camera.

(FWIW: My "dumb" camera is collecting dust. I rarely take it out, and never bring it on vacation.)

This doesn't have anything to do with the sensor. How sensor outputs are mapped to display inputs lies 100% within the domain of software.
