@Rroff - Thanks, will give that a go. I'm downloading the CS5 trial as I speak.
@p0ss3s3d - Looks nice in B&W, though the bottom could be cropped as there's a large area of just black (on my monitor at least) that's fairly uninteresting. I do want a splash of orange on this one though, mainly to enhance the sunset.
@Rojin - Indeed, that's certainly interesting to look at and is a nice effect. As said I'm downloading CS5 atm so I can have a play around.
@twoblacklines - Very different approach to most of the others here, not exactly the direction I'd like, but it's an interesting take non the less. The area where the lens flare was isn't perfect, the shadow seems distorted. Compare it to the shot famas uploaded below.
@famas - Very nice, probably my favourite so far. You've done the best job on removing the flare too. I can see there's quite a few tweaks but the overall effect is subtle and pleasing. The only thing I'd do differently is make it a little less yellow as I wanted to keep the orange, personal preference really, it looks great like that. I did contemplate adding myself to the list for the calibrator that goes around, but it seems to have died down, and I'm not even sure how much longer I'll have this monitor anyway since it's developed a fault (with the buttons!) and is in warranty. Can I ask how you removed the lens flare so well? Was it just patience or did a certain method make it easy to get right?
Thanks again to everyone, some really great interpretations on the same shot, shows just what PP can do.
