The following images were taken using a technique called
"off-camera flash".
The idea behind this is that the flash is not mounted on the camera but it's on a tripod (on any other stable surface) and it's triggered using either a cable or a wireless remote control. This way the subject can be illuminated practically from any direction.
The Nissin Di622 Mark II flash unit has a receiver in it (even if it can be used only on channel 1 group A), but the Nikon D60 doesn't have a transmitter and I don't have another flash unit capable of master mode or a flash commander.
The cheapest way to overcome this problem was to buy a wireless flash trigger kit; the transmitter must be mounted on the hot shoe of the camera and the receiver on the flash unit. Don't forget to insert the batteries and set both devices to the same frequency.
Even if the rule of thumb says that the light, when using a flash unit (and not only), should be bounced back from the ceiling or the walls, in this case to obtain a more dramatic effect, I chose no to do this.
I hope you'll enjoy the images, comments are welcome.
