Nostalgia

This plugin gives a result that reminds me of a hand-tinted monochrome photograph or, perhaps, the kind of cheaply-produced and gaudily-coloured magazine covers that I used to see as a child; it was that "childhood" connection that led me to call the plugin "Nostalgia", of course.

The plugin selectively desaturates the image, but also gives a subtle change in hues. The end result is that some parts of the image become monochrome, while others take on a sort of unrealistic-looking colouration. It's hard to describe, so you'll need to try it to appreciate properly what I'm talking about.

Saturation & Balance	These two sliders work together to control the colouration of the image. The Saturation slider has the most dramatic overall effect, while the effect of the Balance slider is more subtle. Actually, if you experiment you'll find that a high saturation and low balance give a result that initially looks very similar to low saturation and high balance. There will be a subtle difference in the image's colour balance, however.
Flourescence	This slider controls the "realism" of the colours. At minimum, the image will be mostly monochrome; at maximum, the coloured areas will be very unrealistic.
Grain	The Grain slider adds some grain to the image, with a bias toward the desaturated areas. Use this to increase the "cheap magazine cover" feel with the more vibrantly-coloured images. With more subtle colourations, add just a little grain for an "arty" result.
Mono contrast	Use this slider to increase the contrast in the less saturated areas...
Colour contrast	...and this one to separately control contrast in the more saturated areas. It may seem odd to separate the contrast sliders like this, but you can get some quite dramatically different results!

	This snapshot of Jack was taken immediately after he'd completed the school's annual "fun-run".
	The default settings give this result. The greens are almost completely desaturated, and the flesh-tones take on a more delicate colouration.
	Same image - but with a little more flourescence and some added grain. You'll need to click the thumbnail to see the full-size image to see the grain properly.
	This is Postbridge, on Dartmoor, in Devonshire, England. Note the brightly coloured flowers - a foxglove and... um, a yellow one which may or may not be gorse.
	Saturation and balance at default, but flourescence at maximum. Again, the greens are almost completely desaturated, but the brightly-coloured flowers keep most of their colour. The flesh-tones of the people on the bridge have a distinctly unrealistic look...
	Increase the colouration a little, and move both contrast sliders to the mid-point for this badly-printed 1958 magazine-cover look. Ahh... nostalgia isn't what it used to be.
