This is probably my favorite photo from that part of the trip. The sea was rather calm in the harbour, and also in the Pacific Ocean outside. However, these rocks were right at the mouth of the harbour and the currents were playing some weird game creating these huge sprays. So I just waited a little until I got this single shot before the boat was moving out of range. I guess I got lucky, but I like how the veil of water at the bottom of the wave is so dark and thick that masks the sea and the rocks behind, and provide this contrast with the crown of clear white spray. I just like how the blues and the whites mix well... and how the spray is so sharp (there was enough light around that I could really use a very short exposure).
This was just when we were moving out of the harbour to sea the high volcanic cliffs (Akaroa is all made in the craters of a huge ancient volcano), and just before we got another surprise... but I will let this for the post of tomorrow...
