I took this a couple of weeks back down at the beach at Clevedon in Somerset. It's a composite of two pictures as I needed to balance out the exposure for both the sky and the beach which differed quite alot due to the dark seaweed and the light sky.
The technique for the composite involves pasting one image over the other in photoshop and deleting away the unwanted stuff. I'll post a more detailed description of the technique once I remember how I did it! It saves messing around with filters and gives a really good representation of what you actually remember seeing as opposed to the really heavy sky the graduated grey filters give you.
Details for the sky and pier:
1/20th @ f22
Details for the foreground:
1/10th @ f22
Focal length:18mm
Camera: Nikon D70
