several lol.. filters are just the tip of the iceberg though. there's a lot of other adjustments that come into play as well, rather than just a one-step process.What filter are you using in Photoshop to create that effect?
i'll be glad to give you an overview. the specific steps will change depending on what kind of look you're aiming for, what colours, tones, and hues you want, etc.Care to PM me the steps?
