Waaay back before COVID kicked in here, I was getting some advice from Peter and others about good setups for BIF.
And I note that Bent's marvellous BlueTit leaving the nest box was shot at 1/3200
I should have considered that before shooting this week.
I'd gone up to 1/2000 but obviously needed more. Despite the fact these two were decelerating you can see the relatively sharp hand of the trainer, and the more blurred image of each bird.
More work needed here (but if I got a sharper version of either of these, I'd be really pleased!)
Any other comments & suggestions are most welcome
