HDR

CINELERRA-GG runs internally in 32-bit floating-point and thus can read and process HDR media. However, there are plugins and tools that can introduce clipping that must be taken into account to keep the whole pipeline in HDR. The manual indicates which plugins limit pixel values in the range (0, 1.0). The easiest way to see if a media is HDR is to use the eyedropper tool (Get Color) in the Compositor window. If we use HDR media and need to do a Tone Mapping to make the pixel values fall within the range (0, 1.0), we can use the Blender Program plugin and, inside it, load the function (found in =>Syslib) tone_mapping.bp. Instructions for using this function can be found here at example 6.
