The DigiPro F2 Flash and Ambient Light Meter v2from Gossen is a high-performance allrounder for analog and digital photographers and filmmakers who use continuous illumination as well as flash. The light meter demonstrates the full potential by means of the incident light metering method which, as compared with the reflected light metering method used by cameras, functions independently of subject quality. The swivel head makes it possible to lower the measuring sensor all the way down to the subject level for macro and tabletop photography
When the shutter pre-selection metering function is used in photo mode, the desired exposure time is specified, for example in order to focus sharply on moving subjects. The exposure meter then determines the f-stop, which has to be set at the camera. By pressing and holding the metering key and scanning the subject in this mode, the contrast range, is displayed at the f-stop scale in f-stop values. When the aperture pre-selection metering function is used, the desired f-stop is specified, for example in order to set the depth of focus. The exposure meter then determines the required exposure time. With the exposure value measuring function, the exposure value as well as various f-stop / shutter speed combinations are displayed. The adjustable correction value with +9.9 EV cover large extension factors for neutral-density filters used for long time exposures in daylight.
With flash exposure metering, it's possible to work either with or without a synchronizing cable. The exposure meter determines the corresponding aperture for correct exposure using the preset flash sync time and displays it as a digital value, and as a flashing point on the analog aperture scale. Furthermore, a marking is continuously displayed for the aperture of the continuous light component, making it possible to estimate the continuous light proportion of total light. If flash power is insufficient to reach a selectable f-stop setting, the exposure meter can calculate the required number of multiple flashes to this end.
The exposure value function can be switched over to a simple measurement of illuminance in lux or fc for setting up film lighting. In the HD CINE mode durations ranging from 1/24 to 1/120 of a second are made available in a targeted fashion, corresponding to frame rates of 24 to 120 fps. In order to do justice to modern HD cameras, the ISO setting has also been expanded to include the value of ISO 850.
