90% of the time, my iPhone photos are fine straight out of the camera as HEIC. But every once in a while, I get something like is described here (or in several other recent similar articles).
I would like to see computational photography applied to raw images from DSLRs and MILCs with APS-C and larger sensors. Perhaps Canon, Nikon, Sony, and Fujifilm could have built-in options in their cameras for ‘social media mode’, with a modicum of noise reduction (honestly unnecessary at ISOs lower than about 1600 for modern cameras), but drastically improved HDR and white balance. Many of these cameras are able to…
Olympus (OM Systems?) should build this stuff into their cameras. I used to have a bit of inkling to some day "upgrade" to full frame, but not any more.

There is no reason to do this. If you want to apply the algorithms and Iphone uses, simply take a burst and post process later for HDR or whatever. I remember being in middle school and messing around with Hugin and my Minolta bridge camera… People value quick shots/edits and don’t care about quality or editing things later don’t mind an iPhone doing all this behind the scene - but it is irreversible. The sort of err…
There is no consumer software that can do what the iPhone does with its sensors. iPhone HDR produces an HDR image file. Consumer HDR apps do the opposite - they take an HDR raw and tone map an sRGB JPEG out of it. The only portable format that really supports HDR images is EXR, so if you're not generating that you're not getting it. (I don't think there's anything that can do deep fusion either, though obviously you…
What file format is this? iPhone produces tone mapped HEIC, yes, but that’s not HDR as you pointed out.
Or do you mean HDR video?
Does anybody know what post-processing is applied to ProRaw images from iOS? I'm guessing true raw (Halide, etc) have none at all, but I recall reading the ProRaw had some applied. I just haven't seen a summary of which steps are applied. 90% of the time, my iPhone photos are fine straight out of the camera as HEIC. But every once in a while, I get something like is described here (or in several other recent similar…
Even for the "true raw" ones, I don't know if they're truly raw. Do they have distortion and light fall-off correction applied?

It does raw in "raw" out. You get a DNG out which is demosaiced. I have not yet looked to see what it's doing under the hood, and how the result compares to EXR. (But in my experience, it seems to struggle with large exposure differences, even when on a tripod).

This looks like iPhone postprocessing problem more than anything else. I have used 3 Google pixel phones (up to pixel 4) and none of them does bad post-processing. In fact, it improves the resolution of whatever you are taking picture of https://ai.googleblog.com/2018/10/see-better-and-further-wit... I never saw any of these phones altering the details like in article.

If you're making the same or very similar edits to a lot of shots by hand, you don't have to do that. You can create a preset from one shot's edits, then apply it to as many others as you like in a single step.
Yeah, Photoshop has actions too. See, photographers have been doing computational photography too, this whole time. It’s just that we prefer to put it together with a general purpose tool, rather than what formula Apple or Samsung has decided would be best.

I always shoot in Raw (using the Lightroom iPhone App) to make sure that this kind of defects never occur. Noise is generally preferable and acceptable that the disaster trail left by denoising et al. At least you can do it yourself in a way that pleases you instead of having a ruined photograph.

as long as there is anything to key onto it's possible to remove the shake algorithmically
> as long as there is anything to key onto it's possible to remove the shake algorithmically Why the requirement? The phone already has accelerometers, doesn't it? In any case, less hake should still be easier for the phone to deal with. Those algorithms aren't flawless.
