If you want your Nikon DSLR to take care of the ISO for you, this video will give you the tips and trick to shoot in manual mode.
Shooting in Manual Mode with Auto ISO definition – In a nut shell, this setup allows you to adjust your F/stop and shutter speed to exactly what you want and it automatically adjusts the ISO in order to generate a proper exposure.
In the video below you will discover why this is so advantageous, why it’s better than using Auto ISO with one of the regular exposure modes, and how to set the whole thing up on your Nikon DSLR.
This set-up is ideal for photographing birds in flight and other wildlife. It makes it much easier to get the proper exposure in a very fast response time. It can help you snap off quick shots when a bird moves between the sky and trees. Without this set-up you would not have the time to make the proper settings changes.
