Colour- Primary & secondary


Primary colours can not be made y mixing, and can make all the other colours on the colour wheel.


Primary colours are... RED,BLUE & YELLOW

Secondary colours are... PURPLE, ORANGE, GREEN

Tertiary colours are... RED ORANGE, RED YELLOW, YELLOW ORANGE, BLUE VIOLET, BLUE GREEN ETC...

A tint is a colour plus white
A shade is colour plus black


Isaac Newton first understood the rainbow and the colours, he did an experiment with a glass pyramid and shone a sing beam of light threw it and out the other side came the light in all its forms... the colours are; Red,Orange,Yellow,Green,Blue,Indigo & Violet.
It is easier to remember the anagram... 'ROY G BIV'



Warm colours are reds, orange, yellow
Cool colours are blue, green, violet.









Triadic colour schemes are 3 colours spaced equally apart on the colour wheel, eg, yellow, red, blue.

Split complementary colour schemes are two colours on either side of its complement colour. for example, blue and yellow orange and orange red.

complementary colour schemes are two colours that are opposite to each other on the wheel one of the examples could be yellow & purple.



















Visual Elemens

The main Visual Elements are ...

Line, Tone, Form/mass, Colour, Shape & Texture

Firstly what is colour?
Colour is light... If you have a Red flower in the light, you an see that it is red. But if you turn off the lights the flower appears to be black because it is dark. Colour is the visual sensation resulting from he reflection of wave lengths of light from reflective surfaces... so what is the colour of the flower ?
We know the flower is red but it is light that is making our eyes see it as a red flower so colour = light or else we wouldn't be able to define colours because they would be black without light.


The 3 properties of colour are...

HUE- the name of the colour.

VALUE- the lightness or darkness of the colour, yellow is the lightest in value and violet is the darkest.

INTENSITY- the saturation of the colour... the purity. chroma, brightness and dullness.
                       Saturated colours are where the colour is more intense.
                       Desaturated colours are where colours are less vibrant.

Pure Hues= Primary colours + secondary colours

Unpure Hues= more than 2 colours mixed together eg, Brown

All colours mixed together make easy to look at colours.

Mass/Form- organic and geometric


There are various ways to categorize form and shape. Form and shape can be thought of as either two dimensional or three dimensional. Two dimensional form has width and height. It can also create the illusion of three dimension objects. Three dimensional shape has depth as well as width and height.

Form and shape can also be described as either organic or geometric. Organic forms such as snow-covered boulders typically are irregular in outline, and often asymmetrical. Organic forms are most often thought of as naturally occurring.


Geometric forms are those which correspond to named regular shapes, such as squares, rectangles, circles, cubes, spheres, cones, and other regular forms. Architecture, such as this example by Frank Lloyd Wright, is usually composed of geometric forms. These forms are most often thought of as constructed or made.

Shape

Shapes and lines are important elements in photographic composition. When properly used, shapes and lines can create a desired effect. As a photographer, you usually have control over the way shapes and lines are used in your pictures. Shape is a two-dimensional element basic to picture composition and is usually the first means by which a viewer identifies an object within the picture. Form is the three-dimensional equivalent of shape.









This image also includes repetition and diagonal lines by the way that the chairs are and the angle they have been taken.

Line

The lines that can be found in images are very powerful elements that with a little practice can add dynamic impact to a photograph in terms of mood as well as how they lead an image’s viewer into a photo.






There’s something about a horizontal line in an image that conveys a message of ‘stability’ or even ‘rest’. Horizons, fallen trees, oceans, sleeping people – all of these subjects have something about them that speaks either of permanency and timelessness or rest.As horizontal lines can be accentuated by shooting in horizontal format vertical lines can be used very effectively by swapping the way you hold your camera into a vertical framing. This lengthens the vertical subject further which can emphasize it’s height.







Vertical lines have the ability to convey a variety of different moods in a photograph ranging from power and strength (think of skyscrapers) to growth (think of trees).
The other option is to break this rule and frame your vertical subject horizontally which will give it the sense that your image can’t contain it (quite effective if the vertical lines are very strong).







Diagonal lines generally work well to draw the eye of an image’s viewer through the photograph. They create points of interest as they intersect with other lines and often give images depth by suggesting perspective.
They can also add a sense of action to an image and add a dynamic looks and feel.
Consider how you might use diagonal lines to lead the eye to your photograph’s main subject or point of interest.



 Of course there some examples of The curve lines are path ways, rivers, flower stems from a garden,the shape of a body ect. This image also includes leading lines.

"s" shape curves:
Examples: the double curve of a river makes an 'S' curve. A path, row of trees or bushes that curve one way and then the other way create the 'S' curve. Look for this type of design and use it in your photos to add interest and beauty.
