Thanks for the comments all. This year I am trying to create some images more interesting than just 'ships at sea.' I am also playing with filters, as you will be able to see in the images.
Chris - Spot on Chris, but i would expect you to get them right
Oneputt - yes, they were transferring fuel. It is unusual for those two ships to do what they are doing as they are both 'Replenishment' ships. Normally they replenish other ships, not themselves
Sheepie - I am aiming for wide-angle distortion in some images. I am practising my WA techniques for some ideas i have for when i get the opportunity. First i need to see how WA looks in a range of situations. So far, it's brilliant for Landscapes (obviously!!)
