These backgrounds are made in Photoshop, all the levels of trees are on seperate layers which will move at different timings to create a sort of paralax.
This is the first version, as you can see it's insanely dark. My laptop screen was really bright, which was fine for me but I soon realised that noone else has similar screens to me! So I had to mess with the settings for ages.
This next one is when I fixed my laptop screen, but then I ended up plugging my PC monitor in and using that instead. The difference between this one and the previous is massive. Looks much better. But it's too blue.
