With the introduction of the Nikon D4S and the D810, Nikon introduced the new sRAW format for saving images. While we have already explained the format in detail in our sRAW format explained article, there were many follow-up questions from our readers, some of whom asked us to provide some image samples from RAW, sRAW and JPEG formats to compare things like white balance recovery and highlight / shadow recovery. In this article, we will explore the sRAW format in detail and show sample images from both controlled lab and outdoor environments, demonstrating what sRAW is capable of delivering when compared to the regular RAW format.
First, let’s take a look at how capable the sRAW format is at recovering white balance. For the first test, we photographed a color chart with the D810 in proper white balance, then changed the WB setting to 2500K (cool) and 10000K (warm). The below comparisons demonstrate the results in both sRAW and JPEG formats to show their differences compared to regular RAW files.
