e3 Flash Control for Built-In Flash
Explanation: This menu defines how the built-in flash shall be used:
- TTL (default): Fully automatic flash exposure
- Manual: The flash will always use as much of its power as you define here, between 1/100 and full power. A reduction to 1/4 will result in half of the flash range.
- Repeating flash: The D7000 emits a fast sequence of flashes and you can choose the number, their brightness and their frequency (in flashes per second).
- Commander mode: The built-in flash will trigger one or several other flashlights that need to be compatible with Nikon‘s flash control. From the Nikon flashes you can use all except the smallest SB-400.
You can manage the built-in flash and the flashes in two groups „A“ and „B“. Which flash belongs to which group has to be set in the flashlight.
For each group you can choose the exposure metering (TTL, manual, none or AA for the flash automatic of the SB-800 and SB-900) and a flash exposure compensation.
The channel must be set to the same value in the camera and in all flashes otherwise the commander mode will not work.
Tips: Most relevant are:
- TTL as the most reasonable flash control for the built-in and also an external flash mounted on the camera.
- Commander mode for a separately placed second flash.
This can give you a lot better light!
If you try the commander mode and it does not work, check first if the channels are set to the same value in the camera and in the flash. The defaults are not necessarily the same!
Make sample shots and then you can play with the light and decide to increase or decrease one of the flashes by setting an exposure compensation.
I would leave „mode“ always on TTL.
The repeating flash is a nice fancy feature to capture different stages of movements on one picture. If you like playing with such things you can get as creative as you want.
