Sekonic L-758DR manual Reflected Measurement Mode spot metering

4. Basic Operation

4.Reflected Measurement Mode (spot metering)

This method measures the brightness (luminance) of the light reflected from the subject. It is useful for distant objects such as landscapes, when you cannot go to the position of the subject, or for metering subjects that generate light (neon signs, etc.), highly reflective surfaces or translucent subjects (stained glass, etc.).

1.Take the measurement by aligning the circle inside the viewfinder with the subject area to be measured.

2.The black circle A in the finder indicates the measure- ment range. The light receiving angle is 1 degree .

< Diopter Adjustment >

Turn the eyepiece @2and adjust the diopter so that the circle in the finder is clearly visible when you look into the finder.

< Step-Up Ring (Lens Hood)> (optional)

The step-up ring (30.5mm → 40.5mm), available as an optional accessory, makes it possible to mount step-up rings and filters. This simplifies the setting of exposure without the troublesome correction calculation of polarizing filters, etc. (see page 52)

The step-up ring can also be used as a lens hood to prevent lens flare and erroneous light measurements from glare, it also protects the spot lens from scratching, soiling, etc.
