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.
