INTRODUCTION Qflash models T4d and X4d provide professional quality lighting for both digital and film cameras. Quantum's proprietary QTTL® Adapters* dedicate Qflash seamlessly to your camera. Also, many features of the Qflash "Digitals" enhance lighting control for cameras without dedicated control. [. . . ] When desiring camera control of exposure using a D series adapter, QTTL mode replaces TTL mode. The QTTL mode does not provide the Linked ratio of Auto or Auto Fill modes, however it lets the camera control flash exposure. The sections that follow explain in detail how to use multiple Qflashes in Wired Mode. 7. 1. 1 Setting the Wired mode and the Control flash The diagram shows a set up for Wired Control. The Qflash displays will prompt you to select the Control flash. 18 Press the Mode I button on the Qflash that you want to be the Control Qflash (usually the one at the camera). The display for this Qflash will change to `Wired Control', and display the data for Remote 1 (R1) and Remote 2 (R2). The displays of the two Remote Qflashes will automatically change to R1 and R2. To change which Qflash is Remote 1 and 2 see Section 7. 5. To designate another Qflash to be the Control, press Set G on the Control flash. Use the Up/Down J L buttons to return to the display prompt: "Press Mode button to select Control flash. " All flashes will display the prompt. Select the new Control flash by pressing the Mode I button on the new Control Qflash. When only one Remote Qflash is attached, the Control Qflash displays a series of dashes for R2, like this: 7. 1. 2 Changing the setting on the Control flash Always select the settings you desire for the Control Qflash first. (If "R1" or "R2" is blinking instead, press the Up/Down J L buttons until "C" blinks). The choices are Man, Auto, TTL, Auto Fill, QTTL (if a D series adapter connects to the camera), and OFF. When the Control Qflash is set to OFF it will not fire, however, Remotes 1 and 2 will still fire (if they are not also set to OFF). 19 Press Set G again to set the parameters for the mode selected. If a QTTL adapter is connected to any of the Qflash 4d's, then QTTL mode will be available for all of the Qflashes. The Control Qflash will display the fill/flash ratio set on the QTTL adapter. Use either the camera's flash compensation, or Qflash's, but not both. Note that in QTTL mode the film speed is controlled by the camera and cannot be changed here. 7. 1. 3 Changing the Remote flash settings from the Control flash Press Set G until "C", "R1" or "R2" blinks in the display. Use the Up/Down J L buttons until "R1" or "R2" blinks. If the Control Qflash is in Auto mode then Linked mode replaces TTL mode. Linked mode (available when the Control Qflash is in Auto or Auto Fill Mode) sets a Linked ratio for Remotes 1 & 2. If both R1 and R2 are set to Linked mode, the ratio will appear next to R1 only, although this ratio is for both flashes. [. . . ] The F number used is based on the existing lighting conditions Set the Film speed you are using. Now adjust the power setting until the flash distance shown matches the subject distance as close as possible. Now the flash will produce an F8. 0 at the subject (8 ft), and it was quickly accomplished without metering. Reminder: If the distance to the subject changes (you move in for a head shot, or move out for a full length) you must change the flash distance readout by changing the power setting. 35 10. 4 Wireless lighting ratios made easy When using multiple lights to light a subject it's very easy to set up a lighting ratio between the Main and Fill lights. Equipment needed: · One Qflash 4d located at camera position · One Qflash / 2/ 2d/ 4d located off to the side of the subject · Two FREEXWIRE's · Two FW31 cables · Two Quantum Turbo, 2x2, Z, or Compact Batteries Set up: Connect the equipment as shown. Typically it is set to one stop under the camera's aperture, but can be as low as 2 1/2 stops under. [. . . ]
