In addition, you can view a variety of high bit depth and/or wide color gamut (WCG) image formats on a capable display: The app also includes some useful tools for HDR developers such as rendering the image luminance as a colorized heatmap, or forcing an image to be interpreted with a specific colorspace (for example, PNG images encoded as HDR10). When viewing the above on a standard dynamic range (SDR) display, the app performs HDR tonemapping to achieve the best possible quality.
