Axis WDR vs WDR?

Author: John Honovich, Published on Jun 14, 2013

Axis has two types of WDR, and if you do not know the difference between the two, join the club. One is called WDR with Dynamic Contrast and the other is called WDR with Dynamic Capture. They even sound almost identical. Recently, we had debates in the IPVMU class about this with attendees conflating both and us arguing that performance differences between the two were dramatic. In this note, we explain the differences between the two and how to best use (and not use) these features.

Background: Readers not familiar with WDR should first read our WDR tutorial
