Setting a personal ISO limit for our bird-in-flight photography takes some experimentation in the field and in post processing.

This article shares twelve new images from some additional high ISO testing I did this weekend. It also discusses where I’ve currently set my personal ISO limit for my OM-D E-M1X when photographing birds-in-flight.
