Adding a very, very subtle layer of noise to an image often works well for improving \
the apparent quality of the image. Noise can add pseudo-detail, which make the image \
appear more detailed than it really is. Noise can also hide imperfections, like \
filter artifacts. 

I often use GIMP to add 'HSV Scatter' noise after noise reduction, after applying the \
'image restoration' plugin, and after enlargement (scaling). The 'Hue' and \
'Saturation' settings are always reduced to zero in order to produce a type of noise \
that is barely visible.
