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 o…

> 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.

A DSLR has, among many other settings, the ability to set white balance manually. Phones, or at least my phone, do not. Some of these settings may be able to be introduced via an update to the camera app, but many (eg manual focus, aperture, ISO) are limitations of the camera hardware.

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

But also some cellphones can capture in RAW mode and some cameras can't.

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…

There is a science of color reproduction. It is quite tough because they way we perceive colors is amazingly complicated. But it is quite possible to make an effort.

Of course, most photography is not about color reproduction but about telling a story.

And automatic cameras (like the way phones are mostly used) take a way a lot of control when it comes to deciding how color look in the photo. On most phones you can frame the image, zoom a bit, and decide when to take the image. Other controls like aperture, shutter speed and color balance are automatic.

This article is awful. It's about smartphone cameras not being able to capture, but the three photos included are all ones that at least somewhat worked. Seems like it would be better to include one that failed?

IKR, went in expecting a natural derivative off based on the title. Not to witness three "perfect" shots which came out okay. Wonder why it's here. It isn't thorough, doesn't provide examples either.

I draw the line at object recognition. If the processing involves semantic meaning (e.g. this is sky, this is a face) instead of geometric meaning (e.g. this is an edge, this is a Bayer filter artifact) then it's lying. It doesn't matter if the object recognition is done by AI (e.g. faking depth of field by blurring background) or by humans applying selective processing (e.g. painting out red-eye effect, or using a graduated neutral-density filter to enhance sky). Honest processing has no awareness of what objects are in the scene.

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?

You can also use a camera app with more settings like ProCam which lets you set the white balance manually.

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.)

They also have a much lower dynamic range, less colour depth and let in less light.

If you want the best of both worlds you can get a mirrorless which is less bulky, but still have a big sensor.

Hold a small piece of white paper up in the corner of the frame. Or get a corner of street sign, etc. (may need to make sure it's illuminated though.)
