This is why I tend to use a telephoto lens, and plenty of cf cards. There are dozens of good compositions within this image, but overall, I think there are too many things going on, fighting for attention, almost all noise, with no theme tune, so to speak, within this one shot. Of course, unless you happen to own the shipping line, you have no control over positioning a cruise ship as it enters harbour , (and if you do own the ship, then you still need to keep check on the depth of the channel, whatever). It then becomes a question of 'pop' - purpose of photo. So, as a general view of the harbour, a reminder of where you were, then it's fine. As an image that I would hang on my wall, my never being there, then it needs something else for me.
I have done my usual cropping thing, in order to try and get some more interesting compositions, something I could think, 'ah, that looks better', but it is a question of time. My first attempt, selecting the rhs, the cloudy side, almost square crop, (leaving out Asher's boat ;-) ,looked much better. However, what I had cropped off, t'other side, that looked better still. I may even try printing a very severe crop - could be useful in comparing the iq of the 40d cf my 20d. This jury of one is still out.
I think it's the drab greenish hills that spoil it - could do with one of Nikolai's fires, I guess.
Best wishes,
