What is HDR?
The process/technique is known as High Dynamic Range processing or simply HDR. HDR and Tone Mapping is a process which two or more differently exposed images (normally one properly exposed, one underexposed by one stop, and one overexposed by one stop) to produce a single image with much higher dynamic color range. Why would we do this? Well, a digital camera sensor is capable of capturing about 3-5 stops of color dynamic range where the human eye is capable of seeing about 11 stops of color dynamic range. What this means is that you see a beautiful scene and then photograph it and then get home and review your images and you are disappointed that your images are just not the way you remember seeing the scene. There is nothing technically wrong with your images, they just are not what you remember seeing when you were there.
