I downloaded a free photo editor online called GIMP, I have ony ever edited pictures on my phone before using the Snapseed app.
First i found very confusing but after messing about with it a bit i have created what i think are some pretty nice colour effects.
There is so much more to play with but i need a lot more practice so i only adjusted the colours and contrast so far.
As i said this is my first time using this so be kind :)
