The top level comment was making a more general claim than just color balance. There are a lot of weird artifacts in phone pictures introduced by image processing overfitting.

I didn't really agree with the top level comment either. This isn't an artifact of sensor size or A/D conversion or any of that. You can encounter the exact same issue with a $40,000 medium format camera if you don't understand photography. What's worse, the article's author never mentions the settings used while taking pictures with his Canon DSLR. The entire article is poorly informed, detail starved, click-bait ga…

You're completely missing the point. Many phones don't have a white balance setting in their default photo apps. They do so much post-processing to correct for various sensor issues it doesn't occur to them to give the user appropriate controls to correct for cases when the correction algorithm fails.

That's not generally how it works. Although it's possible, I promise you professional photographers shooting in RAW are setting their white balance well ahead of importing the files into any photo editing software. You're not going to set up studio strobes, or go do some landscape photography in the evening and just completely ignore your image settings. That's a terribly inefficient workflow. If you want to get a pr…

"That said, in this particular situation, you'd be changing the WB in post."

I definitely would not be doing that lol. I would prefer to set up the camera so that I can get an idea of what I'm actually capturing before I go out. In this case you can take a moment to adjust WB and exposure and then just go out and focus on your images without worrying about too much changing in terms of exposure. I would be super annoyed shooting this type of scene if every time I looked down at the LCD I just saw a normalized scene.

You're wrong OK, just deal with it lol

I've never come across a photo app without a WB setting. These people should discard their phones along with their notions that they are holding a camera that will always perfectly capture the scene as their eyes see it.

You can use the same receptacle to discard your notion that this article had any value.
