A chosen four elements of design are line, shape, form, and colour. All four of these elements are a huge park of design and composition.
A line is from one point to another. A line can be horizontal, vertical, diagonal, straight, curved, dotted, jagged, thick, or thing. As long as it is connecting from one point to another it will be a line. Line can effect an image by showing emotion, connecting objects, and even creating art and shapes.
A shape is a 2D object which can be flat, square, circle, oval, triangle, or any other shape. A shape can effect a composition because it can bring the whole thing together and tie everything together. Shapes can also create optical illusions.
A three dimensional geometric object which can be a cube, sphere, cone, or anything form such as people, animals, tables, and chairs. This can effect a composition because it can really bring things to life and with it being three dimensional it can trick your eye into thinking that it isnt just a 2D object.
Colour refers to wavelengths of light, refers to the value of hue, intensity, saturation, or amount of pigment. Colour can have an effort on a composition because it can make the picture look realistic and show more detail. Also this can show you some things about the season, and time of the day.
A selected four of the principles of design are contrast, repetition, alignment, and proximity. All four of these principles are very important when it comes to composition.
Contrast is the difference in luminance and/or color that makes an object distinguishable. In visual perception of the real world, contrast is determined by the difference in the color and brightness This makes the unique elements in a design stand apart from one and another. One way to really bring something out would be to use contrast. Contrast can be achieved using elements such as colour, tone, size, and more. Contrast allows for the viewers eye to really flow naturally.
The principle of repetition simply means the reusing of the same or similar elements throughout your design. Repetition of certain design elements in a design will bring a clear sense of unity, consistency,and cohesiveness. Repetition breeds cohesiveness in a design. Once a design pattern has been established which can be almost anything, repeat this to make it a repetition.
Alignment is how elements on the page line up with each other and with margins. Proper alignment in a design means that every alignment in it is visually connected to another element. Alignment allows for cohesiveness. Nothing feels out of place or disconnected when alignment has been brought into composition.
Proximity is the nearness in space, time, or relationship. Proximity allows for visual unity in a design. If two elements are related to each other they should be placed in close proximity. Doing this will minimize visual clutter by a lot. This also really increases the viewers comprehension.
