16. TYPICAL LIGHTING SITUATIONS

This section covers some typical lighting situations that photographers find themselves in. Here is how Qflash can help.

16.1 Portrait

Setting up a 3:1 portrait ratio (or any other ratio) has always been time consuming. It is usually accomplished with three flashes: Main, Fill, Background set to manual. Each flash needs to be adjusted and metered separately. If the Main is in an umbrella or soft box this becomes even more time consuming.

The Qflash ‘Wireless Control’ mode (with a FreeXWire) or ‘Wired Control’ mode (with a QF50 cable) provides a method for setting up portrait light- ing which takes only a few moments. See Section 15 for details of the Control Modes.

Set the Qflashes as shown in the diagram to the right. Place the camera at the Fill Qflash position. The Main Qflash can be placed in an umbrella or soft box.

Once the Qflashes are set up, make the fol- lowing settings to the Control Qflash:

Now the system is set up for perfect portrait lighting, with no metering needed. The on-camera Qflash (Control) which is producing a flat light will shut off one stop below the lens setting (Fill). Remote 1 Qflash will pro- duce a light from the left (loop lighting) that is equal to the lens setting (Main). This will achieve the portrait 3:1 ratio. The ratio can be adjusted by changing the F number of the Control Qflash and the linked ratio.

For a ratio of 5:1 set the F number of the Control Qflash to 2 stops below the lens setting, and set the Linked ratio to +2.
