I am simulating a MieSphere (Trying to simulate a Dynabead M270) in Brightfield and Darkfield. Normally, Brightfield microscopy should show a black particle in front of a white background; Darkfield should show a bright particle in front of a black background. This is also the behaviour we see at our microscope in the lab.

But in the simulation it is the opposite, just as it is in your example notebooks (https://github.com/DeepTrackAI/DeepTrack2/blob/develop/tutorials/1-getting-started/DTGS121_tracking_particle_cnn.ipynb). So I guess this is intended? Why?
