Basically, you choose 3 themes from the list and take a photo for each theme you've chosen.
I've put it off a bit as I've been quite busy at work but had a creative spurt tonight and chose my first theme. Nocturne.
I took a few photos to choose from, at this stage I'm leaning towards entering the first of these two.
I'm hoping to get a bit more time over the weekend and next week to choose two more themes and get my entries in!
