Primary and secondary colours. Control the strength of colour.
The first exercise is to take a picture of something that fills the frame and matches one of the primary colours. I have chosen a green cushion for this purpose a purely practical exercise.
What I have noticed is that by changing the exposure the image does not necessarily appear over or under exposed but a different shade of green. It is the saturation that is changing.
Exercise 2. To take pictures are dominated by either a primary or secondary colour. Each image should be taken with the correct exposure as per reading slightly underexposed and slightly over exposed. At the end choose which one matches the primary colours best. If a photo is not correct to begin with this is fine they are not to be discarded. I noted that by exposure we can see a great difference with each colour take the green below as the best example the original image to the left is a dark green similar to foliage in the shape however to the right is a vibrant modern green I believe difficult to find nature perhaps seen on animals such as Lizards, chameleon, We can have colours from almost pastel to dark rich colours. These differences can be huge in our images.
Over exposed is to dark.
Correct exposure is near the correct colour
Underexposed this colour looks too bright
Underexposed this is nearer the primary colour.
Overexposed almost seems not to be orange.
Underexposed -1/2 this seems nearer the primary colour
Over exposed +1
Overexposed by +1/2
Correct exposure best representative of the primary colour.
Correct exposure nearest to the primary colour
Yellow …………… Here I found the correct exposure matched more closely the correct colour. Blue ……. With Blue I found the over exposed and the over exposed were both nice shades of blue however the correctly exposed image seems to be the nearest to the primary colour. Magenta….. With this colour I believe the more underexposed matches the primary colour. Orange With the orange colour the overexposed matches closer the primary colour. Green…….. Cyan …….
This exercise is to show colour relationships. The six colours in the colour Circle. The six colours create three complementary colours. They must also be presented in the correct proportions to be completely harmonious. The following photos are in order to show these harmonious combinations as clear as possible.
Red and Green. 1:1
Orange and Blue 1:2
Yellow and Violet 1:3
Below are images that I found I was naturally attracted to photograph. Originally when I started to do this project I was definitely attracted to more neutral tones of colour however as the project progressed I found myself paying more attention to the colour options available and the following are four images that I believe I was attracted to not because of the content of the image but solely for their colours.
Green:6 Blue:4 Violet:3 In this image I have inverted the colours to the proportions they should be to be harmonious however I naturally found them pleasing.
Green 6: Violet 3 Again I have inverted the proportions of the colours to what should be harmonious nor are these colours a choice of the most harmonious together perhaps it is the fact that they seem odd at ease which caught my attention.
In this image it is really the street artist who has chosen the colour combinations the green stands out as the main colour, the red seems bolder and equally holds my attention they are both in similar quantities and so correct for a harmonious combination. The small quantity of yellow which is considered so bright that a smaller quantity of this colour combines well in this image.
In this image at first glance it appears to be a mix of all colour with no sense however the two primary colours which stand out are the orange of the car and the blue of the sky. I seem to have naturally been attracted to invert the colours to their correct proportion however this time I believe I have done it as the car and the colours were the primary attraction to take the photo in the first place and the sky was merely to balance out the image to help show the car as it was suspended as if driving on air.
This exercise is in order to learn how to use colour effectively in order to convert to black and white. I have taken the image below using the colours red, green, blue and yellow.
This shot is a conversion into Black and white without any adjustments.
I have then used photoshop CS4 in order to add colour filters to a series of shots. The first one I have increased the slider of the red and we note that the red becomes lighter in colour until white if we so desire. The red and similar colours will lighten in shade where as other colours will darken the darkening effect is more efficient in its complimentary colour. Red is complementary to green and so you will see the red filter has opposing effects on each.
I have repeated the process with each colour slider in CS4. The next photo is an increase in the green slider.
The result as we expect is the exact opposite to the above so the green filter has caused the green apple to become lighter in colour however its complimentary colour red is seen to become darker as we see with the red pepper.
In this case by using blue we can see how the blue background has become lighter however its complementary colour is Orange which is not present however we note a similar change in the yellow as it becomes darker.
Above the yellow slider has lightened the yellow pepper the blue background appears darker however the green has also lightened.
I can see how by using colour you could create the most stunning of Black and White images if used in the correct way.
Just to show how we can control to colour to create the maximum contrast in the items I have adjsuted the following shot.
