An artistic composition of the sequence of the Total Lunar Eclipse that occurred on 26 May 2021. The partial eclipse phases show the dark shadow of the Earth falling across part of the lunar surface, while the rest of the surface maintains its typically bright appearance. As the eclipse reaches totality, the shadow covers the entire visible surface of the Moon and we see a beautiful, eerie red/orange colour across the Moon’s surface. The colour is due to the scattering effect of sunlight passing through the Earth’s atmosphere – blue wavelengths of that light are scattered (that’s how we get a blue sky during daytime) while red wavelengths are “bent” (refracted) by the atmosphere and turn the Earth’s shadow a dark red colour which the Moon travels through during the eclipse.
- Partial phases: single exposure, 550mm, f/5.5, 1/80s, ISO 100
- Nearing totality: single exposure, 550mm, f/5.5, 1/6s, ISO 400
- Greatest Eclipse: 7-bracket manual exposure blend, 550mm, f/5.5, 1/6 – 10s , ISO 400
