2-Dimensional composition is defined as the arrangement of various 2 dimensional shapes ie the objects which has only two dimensions, length and width but not the thickness. A 2-D Composition can be created by drawing various objects overlapping each other in such a way that outlines of each object are visible or in other words they look transparent, or by drawing the objects in such a way that the part of one object is hidden by the another object placed over it (or as they are opaque). Mainly they can be classified into open and closed compositions.
Closed composition – In a closed composition objects are contained within the edges of the picture frame.
Open composition – In this type of composition the image looks unrelated to the size or shape of the paper, creating an impression of extending beyond the boundaries of the frame (visual panel).
Colouring a 2-D Composition – To colour a composition always use soft colour pencils which offer smooth application and help to get more colour on the paper in less time. It also helps to generate more vibrant colours and chances of white flecks of paper showing through are minimised. Softer pencils also help to create better blending. Put two to three sheets of paper under your colouring sheet which acts as a cushion and helps to generate smoother colouring. Always prefer block colouring, especially in exams as shading, burnishing or gradient colouring is a bit tricky to use and should be avoided if not asked for. To start with, a regular practice of colouring in small irregular closed shapes can help you to develop control and speed.
