METHOD OF COLOR GAMUT MAPPING INPUT COLORS OF AN INPUT LDR CONTENT INTO OUTPUT COLORS FORMING AN OUTPUT HDR CONTENTThis method comprises expanding lightness or luminance and chroma of each input color along a mapping curve (, ) = 0 which is different from a straight line, where said expanding...
RGB color readouts use 0 to 255 range for pixel components within the SDR range. However, they use the exposure value (or f-stop) convention for values in the HDR range. For example, a value of +0.5 means 1/2 stop above SDR white. This convention applies to both live and sampled re...
hdr output processing to the output of cameras which use offscreen rendering techniques. this prevents hdr output processing being applied twice to the camera's output. sdr rendering hdr output relies on hdr rendering to provide pixel values in the correct format for tone mapping and c...

let context = CIContext(options: [.workingColorSpace: NSNull(), .outputColorSpace: NSNull()]) And then, when rendering the pixels to bitmap, specify the highest precision color format CIFormat.RGBAf to make sure you are not clipping any values. And use nil for colorSpace parameter. You...
