Dusty blue & orange abstract

This and some of its neighbours are from the same basic image. The 'color gradient maps' in Photoshop Elements pick up on the different shades in an image and then apply colours to the various shades. Sometimes the light and shade changes significantly and you get a markedly different look to the picture and that's not just because the colours are different. So it's a matter of playing around until you get an attractive and distinctive look to the image.
