With IDRMyImage you can take a clear shot with no over-illuminated and under-illumimated areas. You can take several shots with different exposure times and fuse them together. It is easy and fast with natural looking results and a dynamic range of tones. No artificial colors or structures are seen. In the application you can easily adjust several parameters of the fusion to get the best result. From the technique it is obvious that the algorithm works best on nearly static scenes.
