Features - Sekonic L-398M Operating Instructions Manual

Nearly all photographic subjects combine complex variations of strongly reflecting
surfaces (high reflectivity) and weakly reflecting surfaces (low reflectivity). These
variations delicately influence exposure determination and to which portion the exposure is
set becomes a vital factor that considerably affects the appearance of the finished
photograph.
Although risk of failure can be minimized by taking maximum and minimum readings of all
portions of the subject, then averaging the values, such an approach is both time
consuming and tedious. The Studio Deluxe II is the answer to this problem. It is designed
around a standard reflectivity of 18%, which has been derived through measurements of
various subjects throughout the seasons of the year.
Consequently, high effectiveness is displayed with subjects possessing reflectivities in the
neighborhood of 18% (people, buildings, etc.) and when this can be considered the
average value (street snapshots, trees, forest scenes, etc.).
1. Optimum exposure meter for incident light measuring method (also applicable for
reflected light method).
2. Freely rotatable light sensor section for very easily performed measurements.
3. Meter stopper mechanism allows operation while hand is released from meter.
4. Meter release mechanism is also included which allows the needle to deflect freely.
This provides greater convenience when determining light balance.
5.
6. Lumisphere detects the same light as strikes the subject. Since subjects are normally
3-dimensional, according to the lighting conditions, brighter surfaces (highlights) and
darker surfaces (shadows) are produced (illumination contrast). The Studio Deluxe II
mechanism automatically takes into account the strength of l ight from all directions,
causing the meter to indicate a value applicable to photography. It is thus most
convenient for determining typical exposures.
Memo pointer enables easier light balance setting.
