Examples

// Linear light, unclamped: 1.0 is reference white. The brightest value is measured as the light level ToneMap fits.
using Raster<RgbF32> hdr = Raster.Load<RgbF32>("desk.hdr");
var details = (RadianceDetails)hdr.Metadata.FormatDetails!;
double? exposure = details.Exposure;                    // the header's EXPOSURE lines; the pixels are kept as stored

// To SDR: tone map, then save. Saving the HDR raster to PNG or JPEG as it is would clip the highlights.
using Raster<RgbF32> mapped = hdr.Derive(ops => ops.ToneMap(ToneMapping.Bt2390));
mapped.Save("desk.jpg");

// RGBE with per-channel run-length scanlines, as Radiance writes them; EXPOSURE only when asked for.
hdr.Save("copy.hdr");
hdr.Save("labeled.hdr", new RadianceWriterOptions { Exposure = 1.5 });
