not my photo - a processing example by abacus07, on Flickr
I used a different program (GIMP - free but a little complicated) and only adjusted the contrast, brightness and lightness of your photo quickly. Your original was overexposed so I darkened the photo (using contrast, brightness and lightness) which makes the dragon stand out more. for other photos you can adjust the saturation (brighter colors) or slightly adjust the hue (changes the color). these are all available in the most basic photo editing software that is probably already on your computer.
