Thanks heaps Eddie. At least now I understand what it is I'm trying to do and why. You make it sound relatively simple. Now if I can just understand how to get the imaging programs to do what you've suggested I'll be laughing.
I love the idea of the flat box. I've tried to do a few off light coloured wall but I've not been able to get the illumination even enough. Great article.
One thing I'd like to see as an adjunct to this article (and I'm not trying to put you back to work Eddie, you've done a fantastic job
Anyone who is able and has the knowledge could do this ), is some additions to the "Iceinspace Glossary of Terms" explaining some of the terms you've used, like Normalization, Registration, Optimization, median combining etc. This could also apply to any other article that is posted that uses specialized jargon to explain the topic.
Mike is there anyway the articles could have a link to a "printer friendly version". I'd like to be able to print articles like these for "in field referencing" and currently it's take 8 pages to print.
