Geir Inge,
just looked through your rejected after coming home from the mountains.

I had a good laugh when you did the narrating in the field. I can see you struggled a lot, fun with the passing cars... ...why are they always there when you record sound!

About the ratio for how much you use of every tape it depends on. Sometimes you are lucky and get good shoots on the first take, other times you really struggle with light, wind and of course the actors (wild animals) which dont want to take part in your film :-)
This is the most facinating part of beeing a wildlifephotographer. You never know what you get.
