Halving the exposure time shows streamers closer to the Sun. The human eye perceives a far greater range of intensity than photographic film. All of the phenomena which require separate exposures to highlight--prominences, streamers, inner and outer corona--are visible all at once when you observe an eclipse in person. That's why folks are willing to journey to the ends of the Earth to see one.
