HOW TO READ THE CHART
The word "EV"stands f or"Exposure Value,' which
representsthe brightness on the
subject you
frame in the viewfinder. The EV is represented
by numbers, and exposure meter of the Petri
TTL
can measure the brightness on the subject
ranging from EV 3 to EV 18 when you use the
film speeded at ASA 1OO (DtN 21ll.
For example, if the exposure meter needle is
centered when you select aperture opening of
f /5.6 with shutter speed of 1/125 second(the
film speed dial is set at ASA 100), the brightness on the subject is supposed EV 12. lf the

FLASH PHOTOGRAPHY
When the exposure meter needle in the vievrrfinder stays below the circle(see page t7)and even a
larger aperture opening and slower shutter speed
can never make it come up into the circle it
shows that the lighting condition is too poor
