About HDR and APNG
HDR (High Dynamic Range) images contain a greater range of luminosity than standard images, offering richer detail in both highlights and shadows. APNG (Animated Portable Network Graphics) is an extension to the PNG format that supports animation. Converting HDR to APNG allows you to create animated images with the high dynamic range detail of the original HDR file. This is useful for displaying complex visual data or creating visually stunning animations.
