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.

Memo pointer enables easier light balance setting.

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 ightl from all directions, causing the meter to indicate a value applicable to photography. It is thus most convenient for determining typical exposures.
