the use of Shapes in visual design - understanding Form and Volume
While photographing a 2d object might
pose its own problems of even lighting, we do not need to use lighting
to visually describe the third dimension.
However, when we photograph a form
- an object that has depth - we need to utilize light and shadow to describe
the object as a tangible shape which is reduced to 2 dimensions in our
photograph. We can chose to do this as in a realistic representation,
or as a visual abstraction.
As the building blocks
of shapes on a 2 D image are squares, triangles and circles, in a 3D form
we have cubes, cylinders, pyramids, cones, spheres as the basic building
blocks. We need to understand that light reacts to the surfaces and edges
of each of these forms in a different manner.
As light can not
bend around corners, with forms that have a hard edge like a cube painted
white, light can be directed to across various surfaces to produce a combination
of tones from black through shades of grey to white. The tone the surface
of the cube takes on depend upon the direction of the light.
||There is a lighting exercise where a white cube is photographed in each of these phases.
