A modeling light mode causes the flash to strobe for a brief time, temporarily providing the effect of a constant light. This allows one to directly see where shadows will fall before taking a photograph. This is more important with film where there's no other easy way to get instant feedback, but can still be useful in the digital era. The entry-level models from each manufacturer are missing this feature, but most middle and higher-end models all have it.
