A unique composite captures the progression of the August 12, 2026 partial solar eclipse set against the countryside of Butser Hill in the South Downs, UK.
To properly balance the extreme brightness difference between the solar disk and the scenic foreground, this image was built using multiple exposures taken at various exposure lengths and ISO settings. Short, filtered exposures taken every 30 seconds across the 2.5-hour event captured the precise phases of the Sun, which were then composited onto a dedicated landscape exposure. This multi-exposure approach ensures both the fine detail of the Sun's path and the rich tones of the surrounding terrain remain perfectly exposed.
During totality of the August 12, 2026 solar eclipse over Guadalajara, Spain, the moon completely covered the solar disk, revealing the majestic structure of the Sun's outer atmosphere.
To capture the vast dynamic range—from the intense brilliance of the solar prominences hugging the lunar limb to the delicate, faint streamers stretching far into the solar corona—this image was crafted using a composite of multiple exposures taken at varying exposure times and ISO settings. Blending these exposures allows the intricate details of the magnetic field lines frozen within the corona to shine through alongside the fiery, crimson prominences at the edge of the disk.
On August 12, 2026, a magnificent partial solar eclipse unfolded across Western Europe, reaching an impressive 87% maximum solar obscuration as viewed from Lüdinghausen, Germany. Captured by photographer Michel Kroll using a Sony RX10 IV with sequential exposures taken every three minutes, this composite image illustrates the lunar limb progressively occulting the solar photosphere as the Sun descended toward the horizon. Even without achieving full totality, an 87% reduction in solar irradiance drastically alters ambient light, while atmospheric extinction and Rayleigh scattering near the horizon shift the Sun's spectral output toward deep amber hues, casting an eerie, twilight-like illumination over the terrestrial landscape.
