Colourizing and using hue/saturation

This is the origional image. its a bit dull so I used the hue/saturation and colourize tools to make it better.

This is the first edited image. I decided to make the water more interesting by changing the colour to something abnormal, but not too wierd, so purple was the best choice. Although I think it looks a little better I think there are now to many colours in the photo.To change the colour of just the water I used the lasso tool to select the area of water and created a new layer containing just the water. I then went onto the  hue/saturation option and turned it to 'colourize' this allowed me to turn the water to many colours of the spectrum by moving the slider left and right to get the desired colour, then using saturation I could decide how vivid I wanted the selected colour.

Here I  have made everything black and white,except for the water. I did this by selecting the background layer and moving the saturation slider all the way to the left.  This focusses attention to the water. I like this picture because its different, but I do think the purple is too differerent.

Here is the same image again but with the water with a more normal bluey colour, rather than an extravagant purple.
