Introduction

HDR stands for high-dynamic-range. Most current hardware & software deals only with LDR rendering; using 8 bits to represent 256 levels of brightness (in Red, Green and Blue). With HDR, you go beyond these 256 levels to have more contrast. With LDR the best ratio is 256:1 (if you use a linear brightness system); with HDR 16-bits half float you can go much higher. You have to move away from thinking in 0..1 levels and starting thinking in luminance levels.
