Tonight we made some dives under the ice in Vinkeveen after sunset. Nice experience. Tried to capture this, but focussing is difficult. Installed a slave-flash on the D12 of my buddy.
Today; ice-diving at Vinkeveen. Great event, hope it continues freezing.
First dive in 2013 was on the Archimedes in Oostvoornsemeer. Tried to make some pics of the crankshaft using a tripod without flashes and again experimenting with a slave flash.
