This morning the weather was ideal: a bright foggy morning. Swallows came up to 1,5 meters to my balcony and I took 142 shots , wonderful shots of swallows entering the nest, in fast flight, frame filled at 85mm and D500 and many more.
Then I checked ... pity ... I hat the camera still set to "M" 6400 ISO f=1.4 and 40th of a second from the night before.
All blown out, all white. Afterwards I took some lesser shots. All crops.
No problem. There will be other bright foggy mornings with lots of swallows and all settings right!
PS: These are "black martins" or "Eurasian swifts". They are the most erratic flyers and one of the fastest flying birds. BUT: I have a colony of a few hundred in my backyard so I have lots of them to practice my birding skills
