Elements of Photography
Visual Rhythm Visual rhythm refers to repetitive patterns within images. This picture has multiple areas of visual rhythm and symmetry pleasing to the eye.
Figure Study A figure study captures the image of your subject in its entirety. Cutting off the hand in this image was an error. Figure studies dont necessarily have to be human subjects. Any object can be photographed as a figure study as long as it is composed in its entirety.
Vantage Point The bear was actually a rug and the photographer laid on the ground to get a straight-on vantage point. Your position in relation to your subject can greatly affect the perception of the viewer.
Balance The position of the steeples compliment each other and add balance to the image.
Contrast Contrast can be used to exemplify areas of photographs and draw our attention to a subject. The lighting is this image makes the long neck of the flamingo stand out against the dark backgound. It also enhances the texture of the feathers.
Texture Texture is often eye- catching and can be manipulated to enhance the image. The wrinkles and rough skin in the trunks of the animals gives us information that we use to perceive much about the elephant.
