I had a trip planned for Wednesday 16th May to visit Omapere when the sun would be setting more or less in line with the wharf. I worked this out using the Photographers Ephemeris. As it happened I decided to do this trip on Tuesday instead, which turned out perfectly as the sunset on Tuesday was great. If I had left it until Wednesday I would have missed out as the weather was overcast with no sunset at all.
Several photos from that trip.
