August 2020 - Dancing Aurora over Kleifarvatn Lake, Iceland

About the Image(s)

Bearing in mind the vagarity of the English weather I have not been inclined to be out before sunrise in the hope of catching a glimpse of Comet Neowise and have settled for a more spectacular (IMO) atmospheric phenomenon for this round - an aurora. Captured on my first visit to Iceland in February 2015 less than 10 hours after arriving in the country for the first time - it was a most exhilarating and unforgettable experience and although I have been fortunate to see the aurora since nothing has compared with the auroral light show that night.

Captured on a Panasonic Lumix GX7 with the Lumix 12-35mm f2.8 lens set at 12mm (35mm equivalent 24mm), f2.8, 10 sec, ISO 1600, no UV filter (shooting through a filter induces diffraction issues which cannot be eliminated in post processing)

Initially processed in colour on a series of Curves Layers both masked and unmasked and a masked CEP 4 Tonal Contrast layer. This mono version is a total rework of the original mono conversion using updated techniques and software. Following a few tweaks with Curves the noise in the colour image was reduced with Topaz Denoise A1 and the image converted to monochrome in SEP 2 and the contrast tweaked in CEP 4 Pro Contrast. To finesse the image 3 further Curves layers were added, masked and unmasked. As usual this jpeg was sharpened using the High Pass filter in Soft Light mode and sharpening halos removed where necessary.
