I had a play around on pixlr to get used to their editing software:
Here is a picture of the Small Faces. The picture on the top is the original image and the picture on the bottom is the picture after I had edited it. The only change I have made is that I have taken the saturation from the picture apart from the boys.
Here is a picture of psychedelic rock legend Syd Barrett. I decided to change the hue of the picture to make it look more 'trippy'. I then opened the picture in fireworks and added a radial blur to make it look like his mind is being altered by the music he is creating/drugs he is taking.
Here is a picture of David Bowie. Like my last edit, I decided to change the hue. I then used an effect found on pixlr called 'kaleidoscope' to create this psychedelic effect.
Here is a picture of George Harrison. To create this effect I used to layers, one the picture of george and one a picture of a psychedelic swirl. I placed the swirl layer behind the picture of george and used a low opacity rubber to rub out the water he is in to reveal the psychedelic design.
Here are two pictures of John Lennon and Paul McCartney. I decided to take the background out of both pictures in order to place both the Beatles together in the same photo.
