Ah ok, that makes a lot of sense. That's probably the reason it almost never happens in germany. There will always be some clouds somewhere.^^
Your sister in law was the one we met when we came back from Knob Peak? Or was that someone else (I can't remember...)? Sounds like something that could happen to me, too. Although I would probably just place my camera on my shoes and some clothes and salvage a shot.
It limits your compositions but it's what I have been doing since I started doing photography and until now a tripod has always been a nice-to-have instead of a must-have for me. I'm sure though it wouldn't meet your quality standards, too bad. : /
Sure, I'm really glad it helped you.
The problem with .PSB, like with .PSD, is that it doesn't safe layer progression if you merge them or use NiK collection. That hasn't been a problem for me because I never merge layers. Some people do that though, for whatever reason...
I can imagine that having a personal relationship with print shops certainly helps.
