It’s my contention that “muscle memory”, fast reflexes and quick thinking are more important in bird photography than they are in most other types of photography.
Flawed images can still be of value to the photographer – they can teach us new lessons or remind us of old ones previously learned but temporarily forgotten in the heat of the moment.
When I have to choose between shutter speed and depth of field I usually lean towards faster SS’s. Sometimes it pays dividends and sometimes it doesn’t.
