Form

Personally, I feel food makes very good subjects for the concept "forms.

Lighting actually plays a very imporant role in bringing out the "3D`ness" of a subject.

Take the above picture for example. Light emitted from the top left hand corner of the photo casts a very nice shadow on the other side of the corn. Shadows when used in an intended manner, gives a added dimension to a subject but when unplanned, can look unsightly and affect the overall visual appeal of the photo.

This picture of a sculpture above was taken at the museum at UCC. When the light from the top of the sculpture cast a shadow on the concave parts of it, the 'form' of the sculpture is further enhanced, giving it a 3-dimensional look.

This is a picture of the same sulpture as above but taken at a different angle. For this, the light was shining from the right side of the photo, casting a shadow at the background. Since the light is shining from a single angle here, we can see the gradual light cast on the legs of the sculpture. This gradient actually also enhances the 'form' of a subject.

Took the above from one of the door at the new built alumni club house. The tones in the photo helps distinguish the contours of the subject (the door handle). If a subject is lit from the side, you will be able to get a higher proportion of the subject to be half lit and half in shadow. This provides the crucial mid-tones that reveals the contours of the subject.
