Page 7: How To Handle The Lmk Mobile Advanced
How to handle the LMK mobile advanced page 7 4 How to handle the LMK mobile advanced This chapter summarizes important rules and empirical values to help the user to handle the camera and the LMK software properly. The non-observance of some advice could result in a considerably higher expenditure of time. -
Page 8: Useful Information About The Camera
How to handle the LMK mobile advanced page 8 4.2 Useful information about the camera Aperture: The camera is calibrated for luminance measurements with adjusted apertures between F4 ≤ Fx ≤ F11. For these aperture values a compensation for the vignetting effect inside the lenses was carried out (shading compensation). - Page 9 How to handle the LMK mobile advanced page 9 Live-View Shooting: It is possible to shoot while viewing a real-time image on the camera’s LCD monitor. This is called Live View shooting. For using the Live View function the Mode dial must be set to the Manual mode ’M’.

Page 10: Instructions And Useful Information On A Quick Start To Luminance Measurements
Choose the exposure time with the main dial near the shutter button. After that or meanwhile check the result of the exposure measurement in the viewfinder or on the LCD display (see chapter 7 in this manual). copyright by TechnoTeam Bildverarbeitung GmbH © 2008... - Page 11 Attention! This AEB setting must be repeated each time the camera is switched on again! Setting the camera to serial capture mode: This setting can be achieved using the picture frequency key, and checked in the LCD display. copyright by TechnoTeam Bildverarbeitung GmbH © 2008...

Page 14: Further Information On How To Make Luminance Measurements With The Camera
These include scenes presenting a largely homogeneous level of brightness. For this kind of luminance measurements, the evaluative metering is recommendable. Here, attention must be paid to the fact that the autofocus of the camera is activated. copyright by TechnoTeam Bildverarbeitung GmbH © 2008... -
