· Leading  Leading lines refers to a composition technique whereby the viewer's eye is attracted to lines that lead directly to the principle subject in the image. Show us an example of an image using leading lines composition · Vertical A vertical line is one the goes straight up and down · Diagonal 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. · Horizontal  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. ·Curved Lines Curved lines may add beauty and grace to an image. They are also used as a popular design technique for leading the eye into the frame. In contrast to straight or patterned lines, meandering curved lines allow the eye to explore an image in a smooth, free-flowing manner. · Symmetrical · symmetry refers to a line that splits an object in half and, if both sides of the object are an exact mirror image of each other, then this object is said to bisymmetrical. The line that splits a symmetrical object is called the line of symmetry. · Asymmetrical · In asymmetrical balance, the two sides are not identical, but differ from one another. However, the elements are arranged so that there is a sense of balance. Unity: unity occurs when all of the elements of a piece combine to make a balanced, harmonious, complete whole. Unity is another of those hard-to-describe art terms but, when it's present, your eye and brain are pleased to see it. Variety: A theory of design that indicates the manner of mixing artistic elements to achieve complex and detailed relationships. Artists who are keen in boosting the visual interest of their artwork use diversity and thus introduce variety in their work. Movement / Rhythm: Repeating art elements in regular or cyclical fashion to create interest, movement, and/or harmony and unity. Rhythms can be random, regular, alternating, flowing, and progressive. Emphasis: Emphasis is defined as an area or object within the artwork that draws attention and becomes a focal point. Subordination is defined as minimizing or toning down other compositional elements in order to bring attention to the focal point. Proportion / Scale: In art the size relationship between an object and the human body is significant. In experiencing the scale of an artwork we tend to compare its size to the size of our own bodies. Proportion refers to the relative size of parts of a whole Repetition / Pattern: Repetition refers to one object or shape repeated. pattern is a combination of elements or shapes repeated in a recurring and regular arrangement; rhythm--is a combination of elements repeated, but with variations · bird’s eye · A bird's-eye view is an elevated view of an object from above, with a perspective as though the observer were a bird, often used in the making of blueprints, floor plans, and maps. It can be an aerial photograph, but also a drawing. · worm’s eye · • A worm's-eye view is a view of an object from below, as though the observer were a worm; the opposite of a bird's-eye. It can be used to look up to something to make an object look tall, strong, and mighty while the viewer feels child-like or powerless A worm's eye view commonly uses three-point perspective, with one vanishing point on top, one on the left, and one on the right Rule of Thirds: The rule of thirds involves mentally dividing up your image using 2 horizontal lines and 2 vertical lines, as shown below. You then position the important elements in your scene along those lines, or at the points where they meet. Framing: The role of any rule of composition is to draw the eye into a photograph. Framing refers to using elements of a scene to create a frame within your frame. For example, you might shoot through a doorway, pulled back curtains, branches, fences, tunnels, or arches to highlight your subject Simplicity: Several methods can achieve simplicity in a photograph. The most obvious is to place the subject against a neutral background such as a backdrop or the sky.
