to the original Bulb Ramping settings, press the "Mode" button.
Our goal with Advanced Bulb Ramping is to verify that Promote Control was able to fit our sequence into
the attainable exposure range. If the attempt was unsuccessful we can go back to Bulb Ramping mode to
change certain settings, or use ND filters in Advanced Bulb Ramping screen to rectify the issue. Promote
Control will try to suggest a suitable solution, making your choice easier.
The "Advanced Bulb Ramping" screen looks similar to the one below. Note that depending on your bulb
ramping settings, the actual values will differ:
ND: none
Shutter: 1.5" ->2"
ISO: 100->800
+ Parameters are OK +
+ START to continue +
Promote Control analyzes the current sequence, and tries to fit the requested start and end exposure to
what it can safely time by automatically ramping the camera ISO. The above screen displays the
following information:
1. Promote Control will start with using shutter speed of 1.5", and end with 8". Note that these may be
different from the start and end exposure times you have set. This change will be matched by a
corresponding change in ISO values.
2. Promote Control will start the sequence using ISO 100, and end it with ISO 800. The ISO values are
calculated automatically to provide the same exposure level as requested originally, while keeping
actual shutter speeds within allowable limits.
3. Current parameters are good to go. Press "Start" to begin taking pictures.
If current settings need to be changed, a variation of the following screen may be displayed:
ND: none
Shutter: 1/20->LONG
ISO: 100->HIGH
- Set Max Auto ISO -
- higher in Setup -
It means the Promote Control was trying to fit the end exposure within the interval limit, but the currently
allowed Max Auto ISO in Promote Control Setup is not enough to make it happen. Set "Highest Auto ISO"
in Setup menu higher, or try increasing your bulb ramping interval in Bulb Ramping screen (press "Mode"
to get there).
