> You can’t do that easily with a dslr, certainly not like a phone is doing right now, which is integrating the last x frames and modulating the digital shutter to capture multiple exposures.

Standalone cameras have been doing this for at least a decade. The same is true for nighttime exposures. That's not to say that the iPhone doesn't do it better, maybe it does, it certainly can throw more processing power at it.

My mirror less Olympus does this as well. Set number of f stops, exposures etc all in-camera

It composes the hdr as well?

The Canon T2i that I bought in 2010 sure did.

All the references I found just referred the auto-bracketing (I.e. shooting the the images with different exposure) but I can't find any mention of in-camera composition of the final hdr - all sources just tell you to use an external software for the HDR composition. I'm not doubting you but this sounds like an undermarketed obscure feature - can you find any references for this feature?

Yup. I was recently doing some night sky shooting with my E-M1.3. Not only does it do what you say, but when using its "super exposure" it'll take multiple shots moving its sensor (using its in-body stabilization) by sub-pixel amounts. This produces from a 15Mp sensor, a 50Mp or 80Mp result - and as a side-effect, the stack of images results in weighted averaging of the pixels, thus doing a fantastic job of noise suppression. And yes, it auto-aligns, at least in the 50Mp mode.

If you're talking about auto-bracketing (AB), yes. But phones are doing more of an AB+. Are stand alone cameras aligning all the pictures in camera? Are they constantly reading the sensor so when you hit the button it takes the last series of shots, aligns them, and merges them?

I've been using AB for 20ish years, but it has never been as automatic as on a phone. It could certainly be that I haven't bought the right stand alone camera though.
