- Nikon D750
- Nikon D610
- Nikon AF-S 24-70mm f/2.8G (non VR version)
- Nikon AF-S 85mm f/1.8G
- Nikon AF-S 50mm f/1.8G
- Nikon SB-700 AF Speedlight
Auto ISO allows you to set the following three parameters: (my settings in parentheses)
-Minimum ISO (100)
-Maximum ISO (12,800 on D750 & 6400 on D610)
-Minimum shutter speed. (1/200)
Now with these three parameters set the camera will choose the best ISO for current lighting conditions while not letting your shutter speed drop below 1/200. Combine this with Aperture Priority and as you choose the aperture the camera will complete the exposure triangle.
This can be a very useful tool in a fast paced setting with constantly changing lighting conditions. On this day in the Page room at the Verandah, with 1500 sq. ft. and 11 foot ceilings, one side of the room next to the sun porch was brightly lit while the other side next the kitchen was much darker with pockets of shadows in between. Combine that with running to the lobby for group pictures and you have a myriad of lighting conditions. The combination of Aperture Priority and Auto ISO is a great way to get you through a stressful and challenging time like this!
