Exercise: Colours into tones in black and white

This exercise required me to take one image and apply four different black and white filters.  Below are the results.

Firstly, this is the image in colour.

Colour - Exercise: Colour Relationships

For the first part of this exercise I needed to take the following colours:
Red: green 1:1
Orange: blue 1:2
Yellow: violet 1:3

These are my attempts at this.

Red: green - 1:1

These are fairly easy colours to find in nature and 50/50 is a simple ratio to apply.

Orange:blue - 1:2
Not such an easy colour relationship to find in nature, so I have improvised!

By setting up a still life composition it made it easier to set the correct ratio.

Yellow: violet - 1:3
Fortunately I had some pansies in my garden with flowers of these colours.  Here I have cropped the photo to achieve the correct ratio.

For the second part of this exercise I have chosen some images with colour combinations that appeal to me...]

This image appealed to me because of the three primary colours: green, yellow and red.  The pattern of the maize adds to the effect created by the strong colours.

This image appealed to me because of the strong contrast between the bright blue and dark red, almost brown colour in the background.  These colours clash with each other and there is an imbalance as such, but this really draws your eye to the paper (man-made flower) and how that conflicts with the natural tree branch and wood.

This is a classic combination of green and red which appeals to me because of the strong contrasts.  The redness of the berries is enhanced by the dark green leaves in the background.

Colour - Exercise 1

For this exercise I had to find colours to match the primary and secondary colours in the colour wheel, and then take photos using the preset exposure and then one stop below and above this.  Below are the results.

Red:

Preset Exposure

One Stop Above

One Stop Under

In this example the stop above is the most realistic and also shows the most details.  This was taken on a very bright day which I think is the reason why the preset option is less realistic and clear.

Violet:

Preset

One stop above

One stop under

The preset default version is the most realistic in for this colour, with the others looking under and over exposed respectively.

Blue:

I found blue to be a very difficult colour to find in nature (with the exception of the sky) so I had to use a man- made object for this example.

Preset

One stop under

One stop over

There is little difference between the colours in these examples, quite possibly because there is little variation in the light and it is a man-made item.

Green:

Preset

One stop above

One stop under

The default setting is the most realistic, however the stop above is not too under exposed.  However a stop under the default is over exposed.

Yellow:

Preset

One stop above

One stop under

As with previous colours, the preset is the most realistic and the next are under and over exposed respectively.

Orange:

Preset

One stop above

One stop under

 As before, the different stop settings have made the image under and over exposed respectively.
