OCA – Digital Photographic Practice
Project 3: Processing the image – Exercise 17: Colours into Tones 1
The purpose of this exercise was to choose an image with at least two strong tones, I chose greed and red. Using the channel sliders on Photoshop Black and White I needed to create two opposite versions of the image in black and white.
I selected the following images from my database from 2011.
A Nikon D300 camera and Nikon 105mm Macro lens were used.
Original Colour
Converted Default Black & White
Black & White Increased Green and Decreased Red
Black & White Increased Red and Decreased Green
You can see from the images above that by increasing the red slider on the black and white option within Photoshop, it lightens the red within the image, making it a pale grey. This obviously has the reverse effect when decreasing the red slider; it then darkens that particular colour within the image.
This exercise has helped me understand how by using the sliders within this option it can affect the complementary colours within an image.

Project 3: Processing the image – Exercise 18: Colours into Tones 2
The purpose of this exercise was to choose one image from a selection of three topics and make practical use of the channel mixer adjustment within your particular editing software. I chose a photograph from a previous visit to York of a street scene with haze.
A Nikon D300 camera and Nikon 18mm-200mm lens were used.
Original Colour
Converted Default Black & White
The photograph above is from the original monochrome selection on the channel mixer
section of Adobe Photoshop CS5. No other changes were made.
Converted Manual Black & White
You can see from the image above that by increasing the contrast and then lightening the
photograph using the colour sliders, I have manages to add more mood to the photograph.
Some of the detail in the foreground has been lost with additional black, but the overall
affect is one of looking into the photograph to study what is going on?
This exercise has helped me understand how by using the sliders within this option it can
provide a satisfactory result that on a personal level was superior to the standard option
provided.
