D800 and wireless flash photography problems
Today I played around with the D800 again and gave it a test run in the studio. I encountered problems triggering the flashes via CLS reliably (read below the dashed line if you do not know what CLS is). Here is a video to illustrate the problem.
For any non-Nikonians: CLS stands for Creative Lighting System. It is a protocol which allows the wireless control of flash units. The internal camera flash (or a flash mounted on the camera) acts as so-called Master flash and “morses” light signals to all other flashes, the so-called Slave flashes. After this the flashes fire with the strength the master flash indicates. If flashes were humans, it would work like this:
Master: ”Hey Slaves, listen up. We are going to fire now. Flashes assigned to group A: Upon the signal you will give a burst with 1/10th strength. Flashes assigned to group B: You will fire with 1/20th. The signal is 1-2-3-fire, understood ?”
Slaves: ”Ok master, waiting for your signal !”
Master: ”1,2,3-FIRE !”
And off they go. This happens within fractions of a second and is usually not noticed by the photographer.
