Off Camera Flash: When to Use a Dedicated Cord for TTL Control

The off camera flash is one of the cheapest and the easiest ways to improve the quality of your photographs. It offers quite a few advantages in terms of reliability and cost over the traditional way of implementing a flash. The following article looks at how and when to use a dedicated cord for TTL control.

The Dedicated Control Cord

The dedicated cord for TTL control is one of the best and quickest ways to get the flash off the camera. It is also the cheapest and easiest. All you have to do is plug in the camera using a PC cable and then fire the flash and not control the light output.

This method is most suited under the following two conditions:

  1. Low Light Photography: These conditions cause auto focus issues in many cameras. An off camera flash being used in such conditions will cause a drastic improvement in the autofocus department for your camera.
  2. Need for Better Control: The traditional flash offers no control in terms of how the flash lights up the entire location or room. An off camera flash allows you to control this by bouncing light off many objects and giving it a direction.
