So far we have covered many different ways you can use your flash on-camera such as bounce and diffused flash and hopefully you have mastered those. Now we will explore numerous ways to effectively use flash off-camera. There are basically two ways to use flash off camera: ETTL and non-ETTL. You can use a Dedicated Flash Cord between your flash and camera and still have all the TTL features available or you can use your flash in a wireless capacity using either the infra red technology built into the flash or separate radio triggersThe content you are trying to access is only available to members.

Using the reflector card, or Flashbender, will work the same as on-camera, but here again, if you reach to arms length you can almost have a portrait quality light by creating a bounce to fill the room and a directional light source that creates highlight and shadows on the subject.The content you are trying to access is only available to members.

WIRELESS TRIGGERS FOR OFF-CAMERA FLASH

The ability to use more than one flash unit allows you a whole new array of photographic lighting potential. You can do traditional portraits using umbrellas or place a flash unit on the background, hidden behind an object, or to splash light on a rear wall. You can put a unit inside a tent to illuminate it at dusk, or create fake campfire light.  There are many places you can put off-camera flashes for creative effects, but first let’s look at how to make them work.

There are problems with optical slaves however. If you are using several flashes in a brightly lit area, the slaves may not ‘see’ the master flash fire due to the brightness level and then will not trigger the other units.  There is no cure here unless you can turn off the lights to make the room brightness lower, then when the flash fires, the optical slaves pick up the brightness change easier and will trigger their respective flashes.The content you are trying to access is only available to members.

3) Trigger the pre-flash first and then open the shutter to take the picture. This method works pretty well. What you do is, with all flash units setup and ready, you trigger the pre-flash by pressing the FV button on the Nikon (be sure and set this up in the menu) and with the Canons you press the FEL button. When you press these buttons the pre-flash fires and you continue to hold these buttons while all flash units recycle. When they have recycled and you are still holding the button, you take the picture by pressing the shutter button. This time the flash will only fire when the shutter is open. You then release the FV/FEL buttons and do the same process for the next exposure. Holding buttons and waiting for the recycle is a slight hassle, but at least you can complete the process with all flashes firing.

Dedicated Wireless

Some of today’s state-of-the-art flash units come with wireless flash ability built in. Canon’s 430EXII and 580EXII and 600EX-RT are three of them while Nikon’s SB 900 and SB700 compliment their line. They have the ability to trigger many more flash units that are compatible with the system.The content you are trying to access is only available to members. Sorry.

SETTING THE CHANNELS

Both the MASTER and REMOTE must have the same channels set to each for them to communicate to each other.The content you are trying to access is only available to members. Sorry.

Radio Remotes Triggers

There are numerous methods for triggering flash using wireless radio technology. There are a number of third party systems designed for wireless triggering and originally most were designed with the studio strobe systems in mind, but the explosive popularity of off-camera flash systems, many have reinvented their products with flash in mind and new companies have sprung up as well. The content you are trying to access is only available to members.
