High Dynamic Range
The image sensor supports three different High Dynamic Range (HDR) modes.
- One mode alters the sensors photosite response curve from a linear default behavior to a shape that is closer to a logarithmic response. This happens before the ADC so no digital data is sacrificed for the additional dynamic range.
- The second mode uses different exposure times for even and odd pixel coloumns. So two exposure brackets can be captured at the same time for sacrificing horizontal resolution.
- The third mode is possible due to the high speed nature of the sensor allowing alternating exposure times with each recorded frame and doubling/tripling/etc. frame rate result in double/triple/etc. the amount of data to be captured.
Smart Dynamic Range
Imagine your camera had a knob for dynamic range like the one it has for shutter speed. You can turn it up or down just as you need it. Sounds crazy doesn't it? That's exactly what this sensor can do. While in general the notion is "the higher the dynamic range the better" you need to be aware that you sacrifice details (digital bandwidth) in shadows/midtones for gains in latitude when you increase dynamic range. This could be undesired in situations like when dealing with fine skin tones or when the scene does not require a high dynamic range at all e.g. when shooting well lit indoor scenes. Smart Dynamic Range for us means that you can dynamically influence the response curve for your particular situation in a range from 10 - 15 stops of dynamic range.
