A) as told, you could increase the RGB value

B) if I understood your image correctly, you could increase the light
sources (ie. put n+1 light sources in 'bout the same place)

C) if using radiosity, you could possibly increase the brightness -value

D) check your gamma settings

For images there's povray.binaries.images and for scene files there's
povray.binaries.scene-files. These are often mentioned as p.b.i and p.b.s-f.
