The main software tricks phones are using are HDR and noise reduction by means of stacking. Your D750 has an exposure bracketing feature and many image editors have stacking functionality. Of course it's hard to get perfectly aligned shots without a tripod or a very good image stabilizer, though I imagine some software can align and perspective-shift them enough to get decent results.

Funny you mention that. I recently stumbled onto software that does just that [1]. It implements Google’s stacking algorithm that it uses for the pixel line. It’s Mac only, but fantastic. Even a two photo stack produces much better noise reduction than I could get from software. [1] https://burst.photo/ https://burst.photo/

  It’s neat. I think it falls short on the comparison to the Google paper where they provide comparisons. However they get major points for the clarity and honesty on the tech.

    It's hard to tell exactly since while their comparison image is the same (the taxi cab) it looks like they've increased the exposure on their comparison. The app also says it uses a "simplified" version of the approach google lays out, but doesn't provide more details about what was simplified out. (and I haven't dived through the code)

I have always assumed (possibly incorrectly) that the camera's physical shutter prevented getting shots in as quick succession as a phone. The thing is, the camera has enough dynamic range I don't feel like I need more than one shot anyway.

  Some mirrorless cameras do this better, offering very fast burst rates with electronic shutter and good enough stabilization for easy stacking.
