This is a photograph straight out of the camera. Experimental series of shots photographing the effects of oil and water. Colour was added by placing coloured cellophane beneath the glass bowl that I was shooting and then firing off a remote flash through the glass. These images were shot in Raw mode and apart from a little boosting of the colour and contrast are as they came out of the camera. This is just one example in Maroon. I have yellow and blue examples which I will will load up if there is interest.
