During a recent swell at Trigg Point Mike Maxted unsheathed his camera an hour before dark.

Rottnest Island and other offshore reefs limit wave size across Perth's metro beaches, even under the biggest of swells.

Higher frequency light (greens and blues) curves more than lower frequency light (reds and yellows) so the greens are left visible after the sun has set. Yeah, there's that, or there's Trigg's Marc Lee flaring up in his bright green hat. All photos by Mike Maxted.//STUART NETTLE
