Can anyone here suggest a good advanced photo seminar or a workshop worth taking?-ilya
Since you're here in SoCal, you might want to check out the Julia Dean workshops:http://www.juliadean.com/
Workshops are at various levels so there might be something of interest to you. Full disclosure - I took one of their fine art inkjet printing workshops (taught by Mac Holbert of Nash Editions) but haven't taken any of their other classes.
If you're looking for a landscape photography workshop that concentrates on working in the field from pre-dawn to after dusk, I like Steve Kossack's trips:http://www.stevekossack.com/
