The software we are talking about today is Qtpfsgui, software for the creation of HDR images.

Often mistakenly tend to confuse with the HDR tone mapping, in fact for HDR (High Dynamic Range) means the overlapping of several photos taken with different exposures to allow the optimum setting for the exposure areas. To get a photo HDR is really required the resumption of same subject in same shot, each with a different light, For this reason, the HDR is possible only with still subjects (monuments, case, vegetable, still life, etc.), you can not apply it to moving subjects (people, crowded streets, animals, treni in corsa, etc.). To get the best from Qtpfsgui it is preferable to take pictures from a fixed point, better still if a tripod.

Below is a screenshot of the running program.

Luminance HDR

The operation of the program is elementary. Are imported shots with different exposures separately, then there is the possibility of choose the effect desired.

For those who are beginners, you can convert a file RAW in più JPG with different exposures. In this way there is no need to fix the stand or pay attention to arm movements, or shooting people or objects moving, everything is made in post production.
