Flash measurements

Flash measurements are extremely easy to make with the Spotmeter F. You just select flash mode, connect the flash sync cord, and set the x-sync speed from 1/1000 to 1 second. To take a measurement, center the 1 spot circle in the finder on the subject, and press the measuring button to fire the flash. The required fnumber (with tenth-stop accuracy) is digitally displayed in the finder and the external LCD panels. Ambient readings are just as easyjust set the shutter speed and press the measuring button.

Exposure-calculation functions to fit your needs
The Spotmeter F offers three exposure-calculation functions for determining exposure in a variety of situations. Highlight-biased exposure Highlight biasing increases the exposure to correctly reproduce highlights as bright areas. Average exposure Averaging determines the average of two measurements, such as measurements of a bright area and a dark area. Shadow-biased exposure Shadow biasing reduces the exposure to keep shadows dark and prevent shadow details from being washed out.

Brightness-difference measurements to monitor scene lighting conditions
Brightness differences between various scene areas can be determined by setting the calculated exposure reading as the standard exposure and then measuring other important areas of the scene. The Spotmeter F will then display the brightness difference in stops between the measured area and the standard B exposure. This function can be used to determine how the various areas will A be reproduced or what the scene contrast is. Highlight, shadow, and C average exposure readings can be used as the standard exposure.

A B A B C C A

A Standard exposure B Brightness difference = +2.5 EV (Monitored area is 2.5 stops brighter than the standard exposure) C Brightness difference = -2.9 EV (Monitored area is 2.9 stops darker than the standard exposure) Pointers B and C indicate the aperture for the respective monitored areas.
Digital and analog displays
Exposure readings are shown digitally in the meter's external and viewfinder displays. The external liquid-crystal display (LCD) also has an analog f-number scale. Pointers on this analog scale can indicate up to four exposure readings. This full range of exposure information makes it easy to determine the optimum exposure in nearly any situation.

Data storage function
Even when the Spotmeter F is switched off, ISO film-speed and shutter-speed settings are stored by the meter. When the meter is switched on, the most recent digital exposure readout and any memorized data are displayed.

Bright viewfinder image

The measuring spot in the viewfinder defines the meter's 1 angle of acceptance and indicates the area being metered. f-numbers, exposure values, and difference in brightness are all displayed digitally in the viewfinder.

Optional close-up lens

A close-up lens is available separately for the Spotmeter F. With the lens attached, you can take readings of subjects from 0.6 to 1.4m (2 to 5 ft.) away.

Power source

The Spotmeter F is powered by a single AA-size 1.5-volt alkaline-manganese, carbon-zinc, or 1.2-volt nickel-cadmium battery. Low power is indicated automatically. All indications on the LCD panel will start blinking when the battery needs to be changed.

Names of parts

q Power switch Use to switch off the meter to prevent battery drain from accidental readings. w Shadow key To bias exposure for a dark shadow area, measure the dark area, then press shadow key. e Averaging key To calculate the average exposure of a scene, measure and memorize readings for both bright and dark areas, then press averaging key. r Highlight key To bias exposure for bright, highlight areas, measure a bright area, then press highlight key. t Data panel Easy-to-read liquid-crystal display (LCD) gives you all the information you need at a glance. y Measuring button ln ambient mode, you can take continuous readings by holding the button in flash mode, the flash is fired and a single reading is taken when the button is pressed. u M-CLR(memory clear) key Press to clear memorized exposure readings.
i FNo./EV key Press to select either the f-number (FNo.) or exposure value (EV) digital display. o ISO/TIME key Press to display film-speed settings from ISO 12 to 6400 or shutter-speed settings from l/8000 sec. to 30 min. (and a l/50 sec. cine setting) in ambient mode and l/1000 sec. to l sec. in flash mode.
!0 RECALL key Press to recall an exposure reading to digital display. !1 Metering mode switch Set to "AMBI" mode for ambient light readings. Set to "FLASH"mode for flash readings. Memorized/displayed readings are cleared when switch is moved to either setting.
!2 Increase and decrease keys
These keys are used to set the shutter speed in full stops or the ISO film speed in one-third stop increments. Settings change continuously when a key is held down.

Optional Accessories

Sync Cord III
The Sync Cord III is a 5-meter long cord that connects to the meter, flash unit, and camera's sync terminal simultaneously, making possible meter-flash and camera-flash synchronization without changing connection.
!3 M (memory) key Press to enter exposure reading in memory. Up to two readings can be stored, and will remain displayed on the analog scale. !4 Display illumination button Press to illuminate viewfinder display for viewing the digital readout in low light. !5 Sync terminal For flash readings, insert flash's sync cord into sync terminal. Terminal is threaded to secure the optional Sync Cord III.
