Sorry for the delayed response but it was one of the frenetic weekends. Thanks Bruce and Dave.
Chocolates Bruce? Sounds great although I half expected Nikola to mention something fantastic with chocolate that would absoutely make my mouth water. Actually, I like experimenting with depth of field and focus stacking to selectively focus.
Dave, I agree that taxonamy has chosen a particulary ugly name, when it reclasified some of my favorite cacti. I don't know whether the differentions between members of the senilis complex were significant enough to demarcate species. Nevertheless, they seemed useful to aid discussion. One the bright side, it casues less consternation when the increadible tag stealers visit and by stealth of night appropriate my labels .
Regards,
Irwin
