(optional Bare Bulb Enhancers QF62Bs and QF62Bg) and TELE (for optional QF63B Tele photo reflector). The reflectors must be repositioned manually.

Notes:

When using QF62B s/g the manual parameters are accurate only for an open area. In medium and small rooms the very widely dispersed light will bounce off nearby walls and increase exposure. A practical solution when using QF62B in small rooms is to meter the light, or use Auto, TTL, or QTTL modes which will provide better exposures and attractive, soft lighting.

When using a Telephoto Reflector QF63B the Auto mode cannot be used because the flash sensor is blocked. Use Manual, TTL, QTTL, Strobo or Linked modes.

Use “B” series reflectors (QF61B, QF62B g/s, QF63B) with Qflash 5d-R. The standard QF60B reflector mounts to Qflash 5d-R as well.

Distance Units

Set your preference for the display of metric (M) or US distance (Ft) units. Guide numbers also change accordingly.

8.2 Option Menu 2:

Exposure Compensation

Quantum calibrates Qflashes to American National Standards Institute (ANSI) standards with laboratory equipment traceable to the National Institute of Standards and Technology (NIST). From time to time, photog- raphers may wish to fine tune Qflash exposures to match their exposure meters, to compensate for variations in cameras or films, to match partic- ular styles, for effects, or for individual taste.

There are two compensations available- one for Manual and one for Auto mode. In QTTL modes Qflash does not control exposure and compensation will not apply. The compensation also does not apply whenever Wireless or Wired appears in the display.

8.2.1 Setting Compensation

Press Set G until the compensation you wish to change blinks. Adjust com- pensation Up J/Down L in 1/3 steps up to +2 or -2 stops. All exposures for that mode will be compensated by the amount selected. You cannot limit compensation settings to individual programs in program mode.

For calibration to a particular light meter you may use the procedures below. It is very important to note the meter measurement type (incident, reflected) used for each procedure!
