I only managed 2 frames today with the PST Mod and the DMK21 (visual was great fun though!). Here's the better of the two, stacked in registax and tweaked and colour added in CS2. If anyone can give me tips on how to get a more 3-D effect I'd be grateful!

Thanks

Helen

Helen, that's a stunning image for sure! The apparent flatness of the image is caused by the lack of limb darkening. Wavelet or any high pass filtering can do this. A neat Photoshop trick to add it back is to overlay the original unprocessed image using "soft light" to restore it and the 3d effect.
