Sliding Switch chonges meosuring ronge of brigt-
ness. In dim condition, slide the switch fully to
the right showing L mork on the frome for the
low ronge. Oiherwise, keep the switch to the left
with  H  mork to oppeor on the frome. lt is
odvisoble olwoys to try the high ronge first unless
it is very dork, ond switch to the low ronge only
when ihe needle foils io defleci.

							4. Colculotion of Exposure:
!s,,
K;
Rotote ihe lorge knurled outer diol to show the
reoding of the needle on the light scole iust under
the Arrow Pointer on the diol.
For exomple, if the needle indicoies I3 on the
high ronge, with the ASA Index set ot I00, then,
show this reoding (i3) right under the Arrow
Pointer so ihot you con get ony combinotion of
Shutter Speed ond {/Stop indicoted on the diols,
for exomple, 11250 second ot f12. Any com-
binotion of shutter speed ond f/stops opposite
eoch other on the exposure conirol diol will give
the some correct exposu re; 1 ll25 second, f/2.8 ;
1/60 second, ll4t 1130 second, f/5.6 etc. The
combinotion you select depends on whether you
wont o fost shutter speed (with its corresponding
lower f/stop number) to stop oction occurring in
the scene; or depth o{ field with o higher f/stop
number ond its slower shutter soeed,

							5. The 2 ond I12 Position:6.Motion Pictures:
L.
The  2  ond  112 positions which represent obrightness rotio of 4 to I con be of greol voluein exposing for color ghots. Attempt to hove theprimory colors of interest foll between the  2 
ond 1/2 positions for most foithful renderingof those colors. While most color films now hoveo lotitude thot exceeds this rotio, if the primorycolors foll within the 2 ond  112 positionsyou con then be ossured thot the bolonce of thescene will be properly exposed within the limits ofthe film you ore using.In cose of block ond white film, the point morked 112 provides o convenient woy of holving nor-mol exposure for  flot  scenes such os londscopeswhere there is no extreme controst between high-lights ond shodows. The point morked  2 pro-vides double normol exposure ond is used forscenes of very high controst such os bocklightedsubiects. In these instonces, set the light scole toeither  112 or  2  insteod of the orrow Dointer.

							7. Reflected Light or Incident Light:
Reflected light is light reflected from the subject to the comero. Incident light is the light which octuollyfolls on the subiect before it is reflected. Meosurement of either reflected or incident light con be usedto determine correct exposure.Sekonic Apex is bosicolly designed for reflected light, but con olso be converted to reod incident lightsimply by sliding the lncident Light Filter.

To toke incident light reoding, move the opoque,semi-circulor filter fully to the left covering theCdS cell. Hold the meter in the some olone osthe comero lens ond ooint the meter fowqrd thecamero.
To toke reflected light reodings, slide the filter
bock to the right, uncovering the CdS cell. Hold
