The original photo was taken 4 years ago whilst on holiday in Menorca. I came across it just after my photoshop workshop and thought I could use it to practice with. I adjusted the levels and increased the vibrance and saturation. I also removed the bit at the bottom left as well as the person in the water and the yellow...floaty things? I did this using the Fill Content Aware tool which i love using, it's great. I'm definitely going to do more of this.
