Your hints & tips are welcome & DO belong here. It's one area of what helps get that perfect photo. Because I see a lot of the same pilots at many of the events I've suggested ways to do that & some co operate to the best of their skill set. Some however are leery & I sure don't push it. The events are usually Fun Fly's & are run at a relaxed pace, and many will make low & slow passes, while others make low high speed passes & I do my best to capture them. Either way I usually take enough photos of every plane that flies to get a few good ones. This is what I ask for when a pilot asks what I like to shoot, banked enough to see both wings, but not much more than that.
This is about right (to me).
