Experiment With Shadows
Shadows can help direct attention to a specific point of composition. They can reveal form or hide features that may be left unseen. They can also be used to add some drama, emotion, interest, or mystery to a photo. They can emphasize the light; drawing attention to highlights in an image.
While it takes practice to perfect the balance of perfect light and darkness in your photo, getting started with shadows is relatively simple. Different ways that can emphasize the shadows can be black and white instead of color.
Assignment: Shoot at least 20 photos of shadows. Use the sun outside or that shines through a window, then try a flashlight or you phone flash light. Try a desk lamp. Time of day will help as well. Early morning sun is the sharpest so get up early to shoot or try later in the afternoon. Both will give longer shadows.
Items to shoot: find items around the house such as a fork, or an object that everyone would know and shoot some with just the shadow of the item and then a few showing part of the item and the shadow. Use your own shadow and try different poses, or someone else's shadows. Try to make shapes or even have a few friends involved to make shapes with shadows or even letters. Get creative!
After you have at least 20 photos, make them all in black and white as well and then pick five of your favorites and upload them for grading.
