Highlight Metering - Fun with shadow & light
The Nikon D750 and D810 share a new metering mode: Highlight Metering. Essentially, this mode protects the brightest highlight in the frame and protects it from blowing out. This works especially well for dark background subjects (theater) and silhouette work.
This photo was taken while my son was Minecrafting ;) Did I need Highlight Metering to accomplish this? No, but it did allow me to grab it quicker, which is great for creative candids or when you just don't have a ton of time to be fiddling with settings (weddings). Concert photography could also be a good candidate for this mode.
