Figueirinha beach, 7 kms far from Setúbal, Portugal.
I was using the 20 D with the 24-70 f/2.8 L USM + NDF + CPF in order to get a very slow exposure.
The camera was on a tripod and I was bare feet.
The tide was going down and I must recommend - if ever you want to shoot in a similar situation - that you must take a tower with you.
Some times the waves against the rocks make large splashes of water which come on ourselves and on the camera.
I had to take my t-shirt to wipe off the camera one time.
Better wrap the tripod feet in preservatives sealing the top with tape.
Be also aware that when standing the tripod on sand, it may move because of the waves.
The shots where I am were done but my wife with the 350 D.+ 16-35 mm
