Like many others across the island, I ventured out to Gardens by the Bay to watch the spectacular annular solar eclipse today. The skies were a little cloudy, but fortunately at the critical moment the sun (and moon) peeped through!
My camera had a built-in neutral density filter, which I turned on to protect it from the powerful light from the sun. After some tries, I started with a shutter speed of 1/4000 of a second, an aperture of F11, and an ISO of 125. As the eclipse progressed and the skies darkened, I lengthened the shutter speed. This pic at the maximum moment was taken at 1/1250 of a second, F11, ISO 125.
If you took any photos, do share them here! (Also, I hope you remembered to protect your eyes from the sun. ☀️😎) – LHL
