. Use the Reflected-light-Type Meter Properly
The sekonic L-98 is on exposure meter of the reflected-
light type. The reflected type of exposure meter meosures
the light reflected f rom o subiect ond indicotes the
correct exposure. Do not use this meter in meosuring
the light incident on o subiect. L-98 is ihe best of oll
the exposure meters now ovoiloble on the morket os it
hos been developed by the engineers of Sekonic Co.,
ofter mony yeors of reseorch. Model L-gg, which uses
codmium sulfide (CdSl, hos on extremely wide ronge of
meosurement ond indicotes the correct exposure of ony
fime qnd ploce. The meter, quite thin in thickness ond
light in weight, moy be corried in your pocket. lt con

o Equip q Bqltery fo the Meter
When using the meter for the flrsi time, put o mercury
bottery in the Mercury Bottery Chomber. Set the bottery
into position so thot thot side of the bottery beoring the
mork "M-D" comes in contoct with the Botiery Chqmber
Lid. When the boftery is ploced in the chomber, moke
sure thot the lid is screwed tight. Depress the Botiery.
Check Knob and see if the Pointer stops in line with
the Bottery Check Point. lf the Pointer does not swing
ond stop ot tlre check point, the Meter is not working
properly ond if this is the cose, you must chonge the
bottery with o new one. The Mercury Boltery of l.3V
is used with the meTer.

Align the Pointer with the Zero Point
After the bottery hos been ploced in the chomber, check
ond see if the Pointer stops in line with the Zero point
when the Switch Button is not depressed. lf the pointer
does not stop in line with the Zero Point olthough the
Switch Button is not depressed, turn with o screwdriver
the Zero corrector ploced on upper bock side of the
Meter so thot the Pointer comes in contoct with the
Zero Point.View original page 7Page 8 · Read text

Use the Reflected Light-Type Meter Properly !
After the boltery hos been ploced in the chomber, the
bottery checked ond the Pointer brought in line with
lhe Zero Point, L-98 is reody to meosure ihe light ond
indicoie the correct exposure with very seldom necessity
for reodiustment ofterwords. The only remoining question
lies in how you use fhe reflected light-iype exposure
meter os instructed.
Set the Proper Film Speed
Checti the instructions shpet of your film ond you will
find the sensitivity figure of the film you ore using. lf
the figure is, soy, ASA 100, hold the Highilow Switch
Lever tight ond turn the ASA Swirch Knob so thot the
ASA reoding "100" oppeors in the smoll slit underneoth
fhe word "ASA."

www.butkus.us 6 Point the Meter ot the Subiect To .meosure the light, point the Meter toword the subiect right f rom the comero position. A. From lhe Comero Position (( LqndscoPes) When you use this method, moke sure thot the Meter is tilted down so thot it points midwoy between your feet ond the port of the sub[ect on which yo desire to put speciol emphosis. Moke sure thot the sky hos no port in the meter reoding. Otherwise, your pictures will be under-exposed. When you toke photogrophs of o vost londscope or mountoins in the distonce, reduce by holf the reoding which you hove token from the Meter. Let us ossume thot one of the meter reodings you hove token is; soy, 11250 second oI f f22, 11250 second multiplied bV 112 equols l/500 second. In other words, the correct exposure is 1i500 second ot f 122,View original page 9

7 B. Meosurement for Close-ups. ((Portroit>> When this method is used, ploce the Meter obout 10 centimeters (obout 3 inches) from the subiect for meosure- ment. In portroiture, the most importont port of the subiect is the foce. Ploce the meter os close to the fqce os possible to hove the meter meosure the light reflected from the foce. When it is impossible to come neor the subiect, use your polm or o stondord reflector in the light condition motched to the importont port of the subiect. In either cose, moke sure thot your polm or the reflector must not be shodowed by the meter.View original page 10

the lever fully in the opposite direction for low light $ meosurement ond ihen depress the Switch Button ogoin.

l. Boloncing for Tone Ronge
The following method is recommended when pictures ore
to be token in the condition thot there is o shorp
controst in the tone ronge of the subiect.
* Ploce the Meter obout l0 centimeters (obout 3 inchesl
a from the subiect to meosure the light reflected from the
highlight ond shodow of the subiect. Choose the inter-
mediote volue from both scole reodings. When portroits
ore to be token in this method, it is odvisoble to use
ouxiliory lights or reflectors so thot the tone ronge will
be of the order of 4,1 or less. (The tdne ronge is the
rotio of highlight to shodow brightness.) ln color photo-
grophy, moke sure thot the tone ronge is of the order
of 4zl or less.t
2, Meosuremenf in qn Extremely Dork Ploce
ln the extremely dork ploce where the light is so poor
thot the Pointer does not swing ot oll even if the High/
Low Lever Switch is set f or low light meosurement
point the Meter toword the light source (for exomple,
the moon). Whotever scole reoding you moy obtoin
'10. must be multiplied by lf one of the correct combi-
} notions of shutter speeds ond' lens opertures is 1115
second ot f 11.4, l/15 second must be multiplied by 10.

fhc Sekonic Metcr L-98 is not provided with o scole
of filter foctors. The operiure volue obtoined from the
metcr must bc increosed occording to the foctor of
the filter you ore using on your comero. Exomple: lf
your filter hos o foctor of 2x ond one of the combi-
notiort3 of lens operiures ond shutter speeds is theI order of 11250 second ot f lB, the correct exposure
J, will, therefore, be of ihe order of l/.I25 second ot f/g.
5. Extreme Close-ups
The true lens operture volue for o close-up is given by
the equotion: -
MXD f=
where T - True operture volue
D - Distonce between lens ond film surfoce
F - Fccol length of lens
Exomple When the focol length of the lens is SO ' millimeters, lhe distonce between the lens ond the film .|00 surfoce is millimeters ond one of the correct
combinctions of opertures ond shutter speeds is the
order of il4 second ot f f 4, the true operture volue is:

This meons thct even if the lens is stopped ot f f 4, the
operture in ihis instonce is the soms os for flB. The'e_
fore the operture musf be increosed by four times. The
