Dynamic range
The dynamic range optimiser (DRO) in its auto mode gives a subtle lift to shadow areas
We have come to expect Sony Alpha cameras to offer in the region of 13EV dynamic range, and there is no reason to believe the Alpha 77 is any different. This means it is able to capture a wide tonal range in one image.
A boost is offered by the dynamic range optimiser (DRO), which is available in five levels of strength, with the strongest setting producing HDR-like results. Kept in its default auto setting, DRO is activated but can be switched off through the main menu. Inspecting the same image with DRO auto on and off, shadow areas are given a subtle extra level of detail.
