this is a really easy photoshop techique that i worked out one day when i was mucking around with photos it looks better with a photo of a person i might add one of them later but yea just something differernt

***edit*** since a few people have asked for a tutorial i thought i would make one.. this techique is very simple:
1. Open up the pitcture in photoshop
2. a open a new layer above the pitcure
3. use the gradient tool (it looks like a square with diffenent tones.. (it is in a meun with the paintbuckt tool
4. draw a line along your the layer that you added
5. change the layer propertie to overlay
6. if you want to change the direction of the colours just change the line have fun..

NOTE this techique works different on all pictures so i had a different picture to show you... and sorry about the wait
