I've included an album with three picture which have a particular effect that I see everywhere and I just wondered how you do it! the last picture in the album doesn't have the effect do you can see the difference.
Can someone please tell what this effect is called? Is it an effect that you can add on to the photo after or is it something to do with the lens / flash that can only be done when the photo is taken? If the former can someone please tell me how to do it!
