WHAT IS HDR?

The HDR stands for  High Dynamic Range photography. It ‘s a method of image processing where the interval between the lightest and darkest  part of image is wider than the traditional methods. The processing of HDR passes through a blending of multiple shots at different exposures carried out in order to compensate the details in the overexposed and underexposed areas in one single exposure that collects all of this information. With the use of HDR technique you can get results that, in a traditional photography would not be possible to reach.

Crucial point of High Dynamic Range is to understand precisely what is meant by Dynamic Range, which is nothing but the ability to capture detail in shadows and light in order to obtain readable information. The human eye is calibrated specifically for this, adapt to different lighting conditions. Our brain can adjust so that we can clearly see the day in the summer or special brightest in a dimly lit room . This adaptability of the human eye is called local adaptation. However cameras do not have and can not have this ability. Each time the number of photons hitting the sensor, this doubles the brightness. This is the linear response. The practical effect of this is that most of the image information is collected in the higher values, while the lowest values are sacrificed. The question is how to capture the dynamic range? Following this HDR Tutorial you will be able to take the dynamic range through the bracketing function which record the scene at different exposures.
