I like this photograph.
It represents a swimming pool on the beach that is flooded at high tide.
I waited until the borders of the pool were completely submerged before taking this image.
The image lacked contrast so during post-processing I added a curve in Photoshop. While adding a control point my daughter hit my arm by accident and due to the sudden movement I pulled the control point down changing the colour and appearance of the image dramatically.
I liked the result so much I did not bother to change it back to normal.
