the positions of the reflections on the detector depend on the unit cell dimensions, but not at all on the content of the unit cell. Therefore a protein crystal with a rather large cell produces a large number of reflections per image. A salt crystal has a very small unit cell and you will only observe very few spots. These, however, will be a very high intensity.
