Hi Alex (in lieu of just 'inviting you next door for a chat'

),
It was more a case of looking at ATWT to see if a series of appropriate masks could be created, to mimic how Ron Wodaski's Zone Process System (which he demonstrates, in his book of the same name, using PhotoShop) could be applied to PI, but in a manner where there is no 'painting' of masks.
In other words, can PI establish, automagically, the same 'Zones' as are described by Ron?
However, after half an hour my brain was in thermal runaway and, like you, I wanted to reread Vincents ancient LE tutorial.
Hopefully I am going to manage to have the (long overdue) one-to-one session with Neil Fleming this Saturday afternoon (using Skype and TeamViewer) and I was hoping to help him understand PI better, and to see how some of his normal PS routines could be 'translated' to PI.
(So, if there are any 'PI Experts' out there who want to be 'on standby' at around 16:00 GMT (17:00 CET, 11:00 EST, 08:00 PWT) on Sat 21st Nov 2009 - I would certainly be grateful

)
Cheers,
