1- I first added highlights to the photograph to make the reflections on the water stand out and make the clouds look darker and more dramatic.
2- I then slightly adjusted the colours to make them more vibrant.
I also experimented by editing the photograph to black and white, to give the sky more depth and make the reflection in the water more prominent. I adjusted the colours (mainly the colours blue, cyan and yellow that are visible in the coloured version) once I had edited the photo to black and white, to create a contrast between the lighter and darker tones in the photograph.
I've decided to use the colour version of the photograph for my final piece as I find the black and white one detracts away from the sky's reflection which is the photograph's main subject matter, while in the coloured photo the blend of warm tones is very clear in the reflection of the water which makes the photograph more interesting.
