The program allows merging several images of the same scene in one. You can merge photos taken with the same exposure or images taken with different exposures. When blending together images taken with different exposure, the program creates an image with high dynamic range of brightness (HDR). Subsequent tone mapping to low range (LDR) uses nonlinear algorithms and allows preserving maximum details of the original images.
