User manual QUANTUM QFLASH TTL ADAPTER

[. . . ] While powerful and extremely versatile, Qflash operation is intuitive and straightforward. Advanced features for most every lighting need can be accessed or ignored as needed. Whether or not you require all of Qflash's capability now, you will want to know it exists when the need arises. *QTTL D- series adapters are optional for specific makes and camera models. [. . . ] Linking the Remote Qflashes lets you set lighting ratios between the Control and Remote Qflashes, from -3 to +3 stops, in 1/3 steps. "Linked" ratios are different from fill/flash ratios: Linked -- sets a ratio between Qflashes (a Control and one or two Remotes). The Control Qflash controls exposure and the Remote Qflash exposure is "linked" by an exposure ratio. 17 Fill/flash -- QTTL D series adapters provide for fixing fill/flash ratios between the camera's exposure and the flash's exposure. Here's an example of using both ratios: A QTTL adapter is connected to a camera set to f/8. The light produced by the Control Qflash will be F/4, 2 stops less than the camera. A Remote Qflash off to one side is Linked to the Control Qflash at +2 stops. The light produced by this flash will be f/8, 2 stops above the Control Qflash. In this example the Control Qflash located at the camera position provides the "fill" light while the Remote Qflash provides the "main" light. 7. 1 Wired Control Mode using only Qflash 4d's Qflashes are connected with cables such as QF50 for the Wired Control mode. Even more lighting versatility becomes available when a D series QTTL adapter is connected to a camera. Then Auto mode is replaced by "AFIL" (Auto Fill) mode, and in addition to a Linked ratio between Control and Remote Qflashes, a flash/fill ratio can be set between the camera and the Control Qflash. 7. 1. 4 Changing the designation for Remote 1 and Remote 2 You may wish to change which Remote flash is designated R1 and which is R2. As you change this Remote flash, the second Remote Qflash (if connected) will change automatically. Each Remote Qflash will pick up its settings (R1 or R2) from the Control Qflash. 7. 2 Multiple Qflash Operation with models T, X, T2, X2, T2d, X2d, T4d, and X4d Qflash models may be mixed in multiple flash setups. The Wired Control features of Section 7. 1 will not be available, however, synchronization, fill ratio, and TTL control can be achieved in various setups discussed below. The position of different Qflash models is not important, and the models may exchange positions in the examples shown. The examples below illustrate Qflash T- model types, although X- model types work in the same way. You can connect any number of Qflash units together in any of the examples below. 20 7. 2. 1 Two Qflashes in Manual or Strobo mode Each Qflash works independently. This allows you to increase power, create multiple light sources and to set ratios manually. 7. 2. 2 Two Qflashes in TTL or QTTL mode For this setup use either QF series TTL adapters, FW series TTL adapters, or D series QTTL adapters. This setup can increase power and / or create multiple light sources with TTL control. 7. 2. 3 Two Qflashes in Auto mode This allows each Qflash to have its light output independently controlled by its own sensor. 21 7. 2. 4 One Qflash in Auto mode, one in Linked mode With the Qflash Model T/T2/T2d in Auto mode, the TTL mode of the Qflash 4d is replaced by Linked mode. The `Linked' unit's light output will be controlled by the sensor of the unit in Auto mode. [. . . ] As long as the subject is within the Sensor Limit it will be lit properly. 34 Suggestion: Use Program mode to preset a number of Auto, Auto Fill F stops with/without Sensor Limit for easy use during your photo shoot. 10. 3 Manual shooting made easy Nothing can beat the combination of a flash meter and a flash set manually. Setting the flash for a manual power setting and taking an incident meter reading takes time and resources the average photographer may not have. So we use automatic and know that in some situations the sensor may be fooled. Your subject is located 8 feet from your camera Start by selecting the F number you want. [. . . ]
