Close Up Diffusers
In photography, a diffuser is basically any material that is capable of letting light scatter or diffuse through it. It may be a translucent or rough-surfaced reflective material as they both scatter a light's rays and soften the light. A close up diffuser attaches to the camera's flash shoe and it is designed to provide soft lighting for your photos. It will also help you to take natural close-up photographs with the built-in flash. A diffuser can cut down on harsh reflections and also cut down on the light itself.
You can also make your own diffuser for photography out of various materials including nylons, scarves and fabric. There are many art photographers who have used lace as a diffuser and as an artistic element.
A close up diffuser can be bought starting at about $35, but why not try making your own first before spending money on a real close up diffuser.
