When ND filter policy is set to "start", a similar line appears:
ND: start 1.0EV+2.0EV
The above line indicates that you would like to "start" with a set of two ND filters - first filter of 1EV,
another one of 2EV. Promote Control then does the following:
1. Recalculates the start exposure accordingly. If all exposures can be done safely, it will allow you to
proceed.
2. When you press "Start", it will prompt you to put the filters on, and press 'Start" again to continue.
3. It will expect you to be around to remove specified filters one by one when prompted by a message
on the Promote Control screen.
When ND filter policy is set to "end", a similar line appears:
ND: end 1.0EV+2.0EV
The above line indicates that you would like to "end" with a set of two ND filters - first filter of 1EV,
another one of 2EV. Promote Control then does the following:
1. Recalculates the end exposure accordingly. If all exposures can be done safely, it will allow you to
proceed.
2. When you press "Start", it will prompt you to take the filters off, and press 'Start" again to continue.
3. It will expect you to be around to add specified filters one by one when prompted by a message on
the Promote Control screen.
When ND filter policy is set to "keep", the following line appears:
ND: keep 1.0EV+2.0EV
The above line indicates that you would like to "keep" a set of two ND filters through the complete
sequence - first filter of 1EV, another one of 2EV. Promote Control then does the following:
1. Recalculates both start and end exposures accordingly. If all exposures can be done safely, it will
allow you to proceed.
2. When you press "Start", it will prompt you to put the filters on, and press 'Start" again to continue.
3. It will NOT expect you to be around for filter handling. The "keep" setting is therefore handy when
you do not want to closely watch Promote Control screen for filter handling messages.
IMPORTANT: ND filter handling routine assumes the start and end exposures were metered without ND
