Diamond ring after the end of total eclipse

The resulting image was made from 63 digital images and a single image taken on a classical film. This combination makes possible to handle easily the brightness ratio over one to million. It would be impossible using a digital camera only. The classical negative film has an extremely high dynamic range which is highly over possibilities of the digital photography.

ProcessingComposition of 63 images digital images (D) and one image taken on classical film (B). Eclipse images were aligned by means of phase correlation, composed using of LDIC 4.0 software, processed using Corona 4.0 in order to visualize coronal structures. Final processing was done using ACC 6.0 software.
