Hi,

I am trying to implement exposure bracketing on my 1800 u508m/c cameras with no success so far.

After entering the SequencerConfigurationMode and defining all the steps of my sequence - 3 steps with increasing exposure time - I am able to start the acquisition through cam.start_streaming(). As far as I understand, there is no way of grabbing an n amount of frames from the camera while the sequencer is enabled. One would have to grab frames from the buffer while streaming, get the exposure times from the chunk data transferred together with the frame, and stop streaming once a certain number of frames has been reached.
Is that correct?

What I am looking for is a solution close to what pypylon does, i.e. cam.StartGrabbingMax() to be able to define the number of desired frames.
