Everyone one of us who owns an Alpha DSLR, no matter what model, knows (to a bigger or lesser amount) what the Dynamic Range Optimization or DRO Function is.
What some of you may not know is that the technology behind DRO isn't developed by Sony, but licenced from a company called Apical. Apical is a company that develops software used in cameras from major brands, including Sony, that aims to deliver photographs closer to the way we see them with our eyes.
Digital Photography Review has recently posted an article of an interview they did with Apical's managing director Michael Tusch, on which he explains what their software does and what was the reason they created it, along with visual examples of how DRO works better most of the time than using tonal curve adjustment in post-processing.
It's a very interesting read if you're curious about how DRO works, the principles behind it and when is advised to use it and when not to use it.
