They've given me some insights into quite a few new things,
Making slide-shows is quite time consuming and not something I'm going to do that often, maybe only one or two for each trip like these.
I now know how to do a few more things in Adobe Premiere, particularly the stuff that can be done with animation and movement.
I've found a couple of great sources of freely use-able music to give a little background to videos like these and they seem to be making quite nice stuff available.
