Westhaven is a great place to shoot the setting sun's reflection across the marina while getting some lovely shots of the yachts in the harbour.
I will have a demo set of Nisi Neutral Density Filters on hand for attendees to try - this will provide you with a great opportunity to 'feel out' what filters to purchase. Purchase any filter on the night for a 10% discount!
Gear: a tripod, a polariser filter will be useful for the reflections and an ND filter and a ND graduated filter, if at all possible. These aren't completely necessary, but will certainly improve your imagery. A wide to standard zoom works best at this location.
