Exercise: Colours into tones part two

The aim of this exercise, is to make practical use of channel adjustment to achieve a specific effect.

Choose one of the following targets:

  • A landscape in which you emphasize the depth (Aerial perspective) by strengthening the visual effect of hae.
  • A portrait in which you lighten the complexion without significantly altering the tones of the rest of the image.
  • A picture of a garden in which the green vegetation appears light in tone.
  • In addition to this, for comparison, also prepare the default black and white conversion offered by your software, for example, desaturate.

I decided to choose the option of choosing Green vegetation and converting it so the green becomes light in tone.

I chose an image that I took whilst on the Avon valley steam train.

Original Image:


I used a copy of the image and converted it to the default black and white.

I then adjusted the channels in order to produce and image in which the green areas became lighter in tone. This included the grass and the trees.

When looking at the default black and white image, the sky has burnt out. The clouds are barely visible. When I began adjusting the channels, I began by lightening the green to +100, in order to make sure it was as light as possible, and adjusting the yellow to help. I then began altering the blue in order to make the sky darker, which then made the clouds more visible. After that, it was a case of adjusting different channels, in order to produce a balanced image.
