Photogenic Professional Lighting PM400R, PM800R manual Flash Power Bracketing

Flash Power Bracketing:

Bracketing refers to taking up to three (3) exposures in a sequence with different flash intensities, either additional watt seconds or fewer watt seconds, from the displayed or selected “primary” base intensity. The PhotoMaster enables you to set the base flash power and then one high and one low bracketing value. Once the setting(s) have been pre-set, a sequence of power levels will automatically occur as you take the exposures. If you wish to only bracket up from the primary, set a HIGH value and leave the LOW value at “0”. If you wish to only bracket down from the primary, set the HIGH value at “0” and set a LOW value.

The 3-exposure bracketing sequence is:

1.Primary power setting.

2.Higher power pre-set.

3.Lower pre-set.

The 2-exposure bracketing sequence is:

1.Primary power setting.

2.Either Higher or Lower (skips the “0” settings)

To set or change the Auto-Bracketing settings:

1.Press the Auto-Bracketingbutton 3 times. This will cause the display to read “br”, then H. .0

2.Press the small up or down (1/10) button to set the HIGH value. The values can be set at zero “0” to “1.5” f-stops above the primary power setting.

3.Press the large up (1/2) button once. This will cause the display to read “L. .0

4.Press the small down or up (1/10) button to set the LOW value. The values can be set at zero “0” to “1.5” f-stops below the primary power setting.

5.Press the AUTO-BRACKETbutton to save these pre-sets.

To turn off the Auto-Bracketing settings:

Setting both the HIGH and the LOW values at zero “0” will turn off the Auto-Bracket feature.

Note: The auto-bracketing settings are retained and sequenced until the feature is manually turned off. If the primary power setting is changed the Auto-Bracketing feature will continue to sequence using the pre-set HIGH and LOW values from the new primary level.

(This bracketing feature is limited by the 6 f-stop range of total watt seconds available.)
