Here will be presented with the pictures received HDR treatment.
HDR treatment is to take several pictures of the same scene after over-exposing and under-exponent (typically 3, 5, 7 or 9 files.) is the first properly exposed.
That is the first picture has good brightness, the second is a step too bright, the third one notch too dark, the Fourth 2 notches too bright compared to the first,
February 5 step too dark compared to the first. (In general we note that by 0 EV, +1 EV, -1 IL; +2 EV,-2EV).
Then we take photos and do a process called ''tone mapping'', which allows overlaying images to make an image that have the right brightness everywhere.
(And incidentally give effect to ''paint'' the picture).
