For these images I created a second layer with the same image on it, then desaturated the top layer. The places that i wanted colour I erased the top layer so it would show from underneath.
For this image I found a picture of a dolphin on the internet and used the silhouet, placing it so it was jumping over a rock. I then added a simple coloured background to make it look like a sunset.
For thse images I found an image of hot air balloons over the Suspension Bridge and changed the colours, for example sepia.
