You can very easily blow your highlights on reversal film (like digital), but exposed correctly, it retains the saturation of sunset and sunrise colours, while negative loses a lot of the colour, appears dull by comparison to what was actually seen, and changes the tone and hue of the colours.

Though you'll have a tough time blowing your highlights on negative film, when there is a lot of difference between the highlights and shadows, negative will capture a greater range of it (as long as you dont underexpose it, overexposing is fine), Astia also has a very good range for this purpose but you need to be careful not to overexpose it still.
