Starting point: HDR - HDR (Radiance RGBE) stores high-dynamic-range lighting with 32 bits per pixel. Tone mapping compresses highlights into display range on export. Lossless quality means larger files than JPEG. Export PNG from HDR at matched dimensions; every pixel maps across, so large sources stay large.
