In addition to what everyone else has already said you could:
Increase the ambient value on just the objects that the shadows are falling
on by using the ambient keyword in the finish blocks of the texture
statements for just those objects.
Add a light source in the vacinity of the objects that you wish to
illuminate more, with a fade_distance on the light source to prevent it from
illuminating areas further away.
And my favourite :-):
You can use two coincident copies of an object that casts a shadow, one with
no_shadow, the other with no_image. Then you can do whatever you like with
its shadows. You can produce partial shadows or very diffuse shadows from a
point light source. Or you can play tricks. The example below uses a filter
to tamper with the light as it passes through the 'no_image' copy of the
object, saturating anything blue in the 'shadowed' area.
