The brightness of objects are not correct, can I suggest that real-world calculations are done to calculate the real brightness of each object, then depending on which objects are being viewed, the screen re-adjusts just like how our eye-lens or a camera shutter speed does, as to bring the lights levels to a normal range.
If done properly, we should be able to see how things really should look.
The magnitude limit should then be replaced with controls similarly found on cameras. also extra camera features could then be added, like different types of lens etc..etc.
