I needed to purchase an external flash unit (one that sits on the camera’s hot shoe) to have more options for light control. I checked out all the usual Nikon versions but wasn’t overly happy with any of them. I found the name Metz deep in the recesses of my recorded photo memory and checked out their flash offerings. They have a model with two flash heads or tubes which means the large head can be tilted up to light the overall scene. The stationary tube is built-in to the body of the flash so it’s light output goes straight out and can provide a catch-light in the subject’s eyes–always a nice touch that adds just a bit of sparkle. This shot of a person at the opening reception of my exhibit at the Swedish-American Museum is a good example of the 2-flash concept. BTW, I don’t have any connection or endorsement deal with Metz or any camera or flash company.
