The basic condition for obtaining an image in HDR technology is to have several versions of an image of the same scene made with different irradiation parameters (possibly several TIFF files, or JPG also obtained from the various call one RAW file.) The best solution is to implement a number of irradiations of the same scene camera mounted on a tripod. Mounting must be as stable, so that the images did not differ from each other the frame, even minimally.
The individual exposure should be made as soon as possible because of the changing landscape elements during such as clouds, waves, moving in the wind, branches or podrygująca boat on the waves. Forgive me, I had to mention it even though it probably did this kind of situation does not meet. Know that I am "łódkofilem" And nothing will change.
