Assembling a collection of objects and lighting them, is a great way to introduce yourself to photographic technique. Choose objects interesting for their color, form, shape and/or texture. Using window light, shoot at different times of the day (if you can) and use a tripod. Direct light is much harder to work with, so set up where you’ll get soft, even, indirect light. Work with how the light falls across you still life. See if you can work with lighting to convey depth and define form. Try using a piece of foam core as a reflector to fill in shadow areas and reduce contrast. As always, create the most interesting composition. Pay attention to how you fill the frame. Are your objects arranged in a way that creates a meaningful, pleasing flow of lines and shapes? Maybe try different arrangements. Always check your background for things that may distract or interfere with your setup.
