22. Bulb ramp / bulb HDR image buffer time

Default: 1800 ms

This setting only applies to Bulb HDR and Bulb Ramping modes. Promote Control knows that your camera needs time to record an image that has just been taken. But cameras' and memory cards' write speeds may vary, and image quality settings may affect the image recording time. Use this setting to tell Promote Control how long your camera takes to record an image.

Bulb HDR and Bulb Ramping exposures must fit the currently set frame interval and yet still have time to be recorded to the memory card. Promote Control will use this information calculate the longest exposure time that can be used. The default setting of 1800 ms (1.8 seconds) should be adequate for most cameras.

If your Bulb Ramping sequences are interrupted and your camera LCD indicates that its temporary image buffer is full, you may want to increase this setting and seeing if that helps. A value that is too high will not have overly dramatic consequences, but may limit Promote Control ability to complete an Advanced Bulb Ramping sequence.

You may also try decreasing this setting when you are absolutely certain that under no circumstances your current camera settings will lead to images that take longer to be recorded. However note that setting this value too low may lead to camera inability to take images in Bulb HDR or (especially) Bulb Ramping modes.

If everything works as expected, it is recommended to leave this setting at default value of 1800 ms.
