      I followed Adams fantastic tutorial for this one. I veered off to photoshop when he started working on the starless image. I feel that the tools in PS are easier to use and come more naturally to me. I finished it off with some colour and contrast adjustments in the Camera Raw Filter. Hopefully I've done it justice and it's not too similar to Adams brilliant result!

      Not entirely sure I understand the rules for the Pro contest for this month, but I'll enter it nonetheless - maybe it gets disqualified as it wasn't released in May?
