Viewfinder skills
Re Halfbakedboy and my comment on Viewfinder skills
Yes I know what you mean and so do I but then we probably have thousands of hours and are quite skilled at what we do.
I should have said leave the camera to him and just fly the aircraft
When doing this for myself I tend to keep the wingtip on the target but you can imagine how with both leaning left to see past a low wing etc?
Anyway I was only trying to help a newbie to aerial photo work because if he takes an interest in it he will be well rewarded.
Edit if you are using the little window you could just set up a mock approach to the target and fly smoothly at 80 with carb heat and 20 deg flap and then practise a go around to do another run.
