Thanks guys.
Alchemy - definitely try and find that old article of Mike's. It's a handy reference piece. Mike was also kind enough to offer a few handy bits of advice when I was having a bit of a struggle with Photoshop a bit earlier on.
Like most things RGB capture/combining is quite straight-forward once you get the hang of it. It's the processing which is the real artform and the area where I'm still very much just the enthusiastic beginner. I just keep practicing and experimenting and hopefully make little improvements over time. There are also plenty of good imagers on IIS who are good enough to offer constructive criticism and advice.
Mike - looking forward to that upcoming article. Should make for interesting reading
Dennis - not sure what the different quality might be? I've certainly taken sharper, more detailed images with the ToUcam than this...but those were in much better seeing.
It will be interesting to see how things go when I get better data. It goes without saying the DMK is a better camera. It just comes down to how well I capture and process. I hope I can do it justice.
