Just over a month ago, some of the trees around here still had leaves. I took the camera with me one evening when we went for a walk around the park.
The leaves were a lovely bright and vibrant colour, but obviously this has been a little touched up in the GIMP afterwards! 
That’s really striking! I probably won’t understand (that’s my fault!) but what did you do to the image?
It’s simple really. I cheated a bit and used a plugin called “urban acid”
Oh right! I had a look at the Urban Acid group on Flickr. I like your use for it compared to most of the stuff I saw.
