Pentax 40 MZ-3i operating instructions Working with user programs, Fill-in flash in TTL mode

Fill-in flash in TTL mode

Some camera models automatically control fill-in flash when in program or automatic mode. The manner of camera internal fill-in flash control varies greatly between the different modern camera models, making it impossible to give a precise description of the individual adjusting procedures. These are normally given in the operating instructions for the given camera. Shadows can also be brightened with a flashgun in TTL mode on cameras that do not feature a special fill-in program or setting. In such cases the effect of fill-in flash depends upon the properties of the camera’s TTL metering system. Con- sequently, in many instances it will be advisable to use fill-in flash in automatic mode.

12. Working with user programs

Fig. 23: Display of an activated user program

￿	Your flashgun is provided with a memory that will enable you to enter your own
	flash programs on nine program places. This is particularly advantageous for
	constantly recurring flash situations.

Program 0 (Prog.0) is loaded when the flashgun is operated for the first time. The home program place 0 covers the standard operating range of the flashgun.

The data that were active just before the flashgun was switched off are stored in program 0. If, prior to switch-off, the data were loaded in program 7 and one or more of the parameters were changed, then it is possible that program „0“ will be indicated. If the flashgun is now switched off, the data will be stored and pre- sented in an unchanged form on program „0“ when the flashgun is switched on again.

The 9 program places have been assigned in the factory as specified in Table 3 of the Technical Data.

The second STO and RCL functions assigned to the buttons are displayed only after the Prog. button has been depressed. The second functions are:

STO = STORE the values indicated on the LC display.

RCL = RECALL = Load the stored data of a user program.
