Although I have so far avoided using the same examples as are used in the OCA course notes, I have on this occasion chosen to work with a collection of peppers of red, yellow and green colour, set on a blue background, much the same are used in the notes. I initially set up the shot with a grey card (not shown) exposed to appear about 18% grey and took a single image under natural lighting with a simple white foamcore reflector placed to minimise shadows around the peppers. The camera was on a tripod and the exposure taken at f/22 to maximise depth of field of the subjects. The image was converted to black and white in Lightroom 4 and then replicated to generate the other images upon which to perform the colour ‘filtration’. The replicate images were processed with the Lightroom presetsThe initial colour version and unaltered black and white conversion are shown below.
