A viewfinder is a piece of card with a hole cut through it in the middle, which can be used to isolate a part of a picture or object. It allows us to concentrate on one small part or area without being distracted by the whole of what can be seen. It is a useful tool that can help children focus or organise their observation and drawing. It can support hesitant children by giving a boundary to what they are looking at and it can guide children who find it hard to keep track of where and what they are looking at, by bringing them back to the same area each time they look and look back. When you are making viewfinders for use with the children you are supporting, take into consideration the size of the card. You need enough card around the hole to block out the rest of the visual information from the child's field of vision, but it should not be too big and unwieldy.
