Gossen 15122 operating instructions Reflected light method

The measurement is taken from the position of the camera towards the subject. In this method, only the light reflected from the subject is detected by the meter. Therefore, the measuring values always depend on the reflection capacity of the subject. As a result of this, bright subjects are reproduced darker and therefore not properly exposed. Consequently, this mode is conveniently used, when the suject does not show too high contrasts between bright and dark areas.

1.3 Duration of read-out in display The Digisix will always display the last function used. The meter does not automatically switch off, as the power consumption is extremely low.

1.2Incident light and reflected light measuring mode

Incident light method

For the incident mode, the diffusor is to be shifted to the left and placed in front of the measuring aperture. Taking measurements using the incident light mode in particular produces perfectly exposed shots. In this mode, the DS measures from the subject towards the camera. This guarantees that the tone quality of the picture is equivalent to that of the subject. This is especially important for very bright or dark subjects. Even under very difficult photographying conditions, as for example with subjects which have a lot of contrast, the incident light mode is a more reliable way of producing well exposed pictures.

Reflected light method

For the reflected mode, the diffuser must be shifted to the right. Care must be taken, that the light measuring aperture is entirely free.
