I recently learnt of a phenomenon that occurs almost every day though most people are unaware of it.
For the briefest moment each evening, the sky turns a deep blue before becoming ink black. And photographs taken during these few minutes can produce quite spectacular results.
|At 7.42pm. Olympus EPL-1 with 14mm lens. F11@50s|
|At 7.45pm. F6.3@50s. Overexposed, sigh.|
|At 7.50pm. The blue period had passed. The sky began to turn black.|
