The ‚Exposure‘ profile menuThe conversion function of the camera in the central shutter mode is set in this menu; this means most of the settings will not be available until the 'Synchronous shutter (snapshot)' mode is activated in the 'Sensor' profile menu.
For a reasonable and fast selection of the options in this menu, the respective chapter in the camera manual (The dynamic (contrast) range of the IBIS5 sensor) is recommended to be thoroughly read.
With 'Exposure precalculation' and 'Manual exposure configuration' the user is given two independent possibilities of adjusting the conversion characteristic of the camera sensor. First the integration time base must be set under 'Exposure precalculation', with the choice being between the current integration time or a new total integration time ('User') or the maximum time possible under the current auto trigger rate ('Trigger'). When selecting 'User' the user must give the 'Total time' in ms. Then, by means of two functions (logarithm of base x, root of base x), the user can approximate the sensor conversion function for up to another three integration times to choose from. To this end, the user highlights under 'Mode' the desired conversion function to be approximated, and enters the value of the base of the conversion function to be approximated under 'Scale' . Finally, the accuracy of the conversion function approximation is defined by selecting the number of integration steps in the 'Slopes' box. All settings are activated by clicking button 'Apply'.
Under 'Manual exposure configuration' the user is given the possibility to define the shape of the sensor conversion characteristic by entering the integration time number and value of up to three more integration steps. .Entering a valid integration time in 'Last slope' - this is absolutely necessary if the above option is not made use of - results in an exposure at a single integration time ('single integration slope'). By entering more valid integration times, exposure at up to four successive integration times can be implemented. Below the 'Last slope' input field are displayed the total exposure time and
the frame rate which depends on the camera configuration in the currently used profile. The value shown in the figure can be considered a good value.
