Seasons

The xero : seasons filter allows you to make subtle (or dramatic) changes to selected colours in the image. For example:

	This scene at Cwm Bychan in North Wales was photographed on a dull, damp, slightly misty day; it was, of course, the height of the Welsh summer. However, with a little tweaking from xero : seasons, we can...
	Freshen up the greenery to make it a slightly-exaggerated spring day, or...
	Make it a reddish-brown, and suddenly it's autumn, or even...
	Make it blue, and now it's a rather outrageous-looking winter! And all this from a filter that...
	...has only three sliders, which act as cut and boost controls for the three channels, plus a fourth slider to control the overall strength of the effect. The preview window here is showing what would have happened if I'd reapplied the same settings to the 'winter' shot. It looked so gaudy I didn't have the courage to click the 'Ok' button!
