Very nice lookin pic. I am gonna have to learn how to do this stacking thing. Is it hard to do? What special software is needed for it?
Thanks

Underwater: Is it hard to do? That's rather relative. Given an ability to understand and control depth of field and to consistently produce properly exposed and in-focus images, it's rather easy to do. If you can't deliver good quality single-shot images, stacking is just going to accentuate any flaws and probably result in a mess. I'm not sure what your skill level is and don't mean to insult you, but I don't want you to be deceived.
You need software to do the stacking. I use Helicon Focus. There might be other packages on the market, but I've not researched them so I don't know for sure. Helicon Focus gives a 30-day trial so you can give it a try to see what results you get.
It's fun to do and there's no harm in trying. After all, it's only data. If you don't like the results, hit delete.
