Waiting for the Light: An Infographic


Landscape photographers are often told “don’t pack up when the sun sets – wait!”

That’s sound advice – the best light often comes after sunset (or before sunrise).

Watching a spectacular sunset last week, I wondered how long after sunset the color in the sky would remain. Using TPE’s elevation above the horizon tools, plus a bit of Excel, I came up with some figures that estimate how long you can expect clouds to retain those spectacular sunset colors.

We put the information into an infographic. There’s even a “science bit” at the end :)
