AccuRaw users might have gotten a bit of a surprise recently - AccuRaw has turned into AccuRaw EXR, and is now at version 3.

The reason for the name change is that the focus of the AccuRaw product has changed a bit, based on what users were actually doing with it. AccuRaw has always been focussed on having highly linear color response, with no "hue twists" or other surprises in the color rendering. As it turns out, that is a very useful feature to have if you're composting stills into video - it reduces the amount of work required for color matching.

In the world of video, especially in the professional cinematography world, the "gold standard" is to use a format such as EXR, which is a floating point format. That allows huge flexibility in the way that post processing is done. So the new version of AccuRaw, now named AccuRaw EXR, supports EXR output.

However, it's more than just a name change. In order to really support EXR output, AccuRaw has seen major changes internally - it now has a fully floating point, non-clipping workflow. For more on why that is important, see this post.
