Contrast: texture, form, light.

Here are some images I shot in the last two weeks with a Pentax ME.  There is a commonality among these images and that is the use of contrast.  The first three use contrast to accentuate texture.  The image of the lone crab apple clinging on is about the contrast of forms, the circular silhouette of the apple against the linear framework of the branches.  The last image is about the contrast of light and dark.
