An exercise introducing the effect of colour filtering into the use of black and white digital editing and black and white – filtered film photography.
The over riding effect is to change the essence of the image and the mood presented by adjusting the image output via colour filtration.
Here we have the original colour image.
Next the 'normal' filtering B&W
Here the Blue filtering is darkened while reducing the red and increasing yellow, the red pepper intensity is far greater
Next we have increased the green fitration while reducing yellow and red, here the yellow and red pepper (left and centre) are 'blacked out' while the green pepper is more natural in tone.
Finally for example, the yellow filter is increased while no adjustment to the others is made.
The end result in this fram is that the yellow pepper is blown out... overly whitened.
Overall, from a simple depictive image (Shore 2009: The Nature of Photographs) the effect of filtering of colours to render a black and white image can have a notable result on the tone, and therefore the mood of the final frame.
