Baily's beads 5 seconds after C3 and iridescent high clouds
This HDR image processing had to manage the brightness ratio more than 1:107. Two
digital images and one classical negative film image taken within one second were used for the
brightest part of the image. The lower light intensity the more images were used. Total number of
used images was 54. The color negative film was used because images taken on this film have no
saturated part, unlike digital camera images. That is why the use of color negative film improves the
display of Baily's beads. The full-resolution version you may download

Processing | Composition of 54 eclipse images - 25 images (1), 20 images (2), 8 images (3), 1 image (4). Digital eclipse images were calibrated by means of large number of dark frames and flat-fields, aligned by means of phase correlation, composed by means of LDIC 5.0 software, processed using Corona 4.1 in order to visualize coronal structures. Final processing was done using ACC 6.1 software. Image processing by Miloslav Druckmüller |
Software | Astro D3F 2.0, PhaseCorr 6.0, LDIC 6.0, Corona 4.1, Sofo ACC 6.1 |
Orientation | Image must be rotated 131° counter-clockwise to achieve standard orientation i. e. solar North up. |
