To show the robustness of our method, the pictures in this stack were captured with a predefined delay (two 33ms frames were dropped between the capture of the source and reference images). The extreme darkness of the reference image causes SIFT to find only few matches (see paper), resulting in a poor warp of the source image ('4'). Our matcher finds enough reliable correspondences to correctly warp the source image ('3'). However, our modification of Exposure Fusion can compensate for the registration problems, even in the case of a wrong warp, at the cost of a loss of range: flip bewtween our HDR and the one created with the source warped with the SIFT correspondences ('5'-'6')
