This was my first image which was the baseline - not very imaginative, with the shelter right in the middle of the frame, the image halved by the central horizon.
In the next image I positioned the shelter at the bottom of the frame. This was largely because the sky provided a plain context rather than the flats and other unattractive buildings which would have been included if I'd gone horizontal.
A more interesting sky would probably have livened this up a little but I'm most concerned about the couple in the background - that red top stands out too much for my liking. Post production was a little cropping to ensure the shelter was in the bottom third of the pic, and I also took some off the right hand side so that the subject was off to the side a little.
I can see now that I probably should have straightened it as well as the sea looks slightly tilted.
This is my favourite of all the images. I'm so pleased with the colours that I didn't alter in any way at all - the complementary blue and yellow work really well here and I love simple shots which focus in on details that you wouldn't usually notice. I wish that I had used a smaller aperture however, to ensure that all the spheres were in focus rather than just the central one.
I do quite like this as well, again because of the simplicity of the colours and the interesting structure, and the lines that the roof makes. In fact, I'd be quite happy to try a version which chops off everything from sea level down and just make this an image of the top half.
The shape of the shelter meant that it didn't completely fill the frame horizontally, so post-production I cut off excess from both sides. Somehow the bottom half feels more crowded to me than the top half - possibly that is because I appear to have got in a little too close and lost some low down detail.
