It can be as fun as playing with your favorite toy: or, creating your own toy! Tweak this, saturate that, move this, twist that. What one set of eyes sees can be quite different from what another set of eyes sees. That's one of the amazing and fun things about photography; your image can mean a million different things, to a million different people, yet still retain the core value of what the photo is all about! It's not just a photo; it's art!
