Thanks for comments guys, overall I am pretty happy with this set although colour balancing and noise reduction are something I'm still struggling with.. John, I will take your advice and calibrate the colour during capture next time.
Here are a couple of post wavelet images (at F20 and F25) before any ACDSee enhancements, I think they have more natural look to them despite the noise. In the end it's so easy to make eveything look like a crayon drawing
Cheers,
Seb
