The 4 leaf barndoor is wildly used for special effect photography. Barndoors are essential for directing the light source in specific areas of the scene and for flagging or blocking light from "spilling" into unwanted areas of the scene. This lighting accessory allows the photographer to control the spread of light from a direct light source. The uses of the barndoor and honeycomb are limited only by your creative imagination and range from hair lighting to subject spotlighting. Use these accessories to control the field of light in your scene and discover new ways to highlight subjects, backgrounds, and add mood to your photographs.
These are simple frames that attach to a studio flash unit and have hinged metal doors. Sometimes two doors and sometimes 4 doors. One would ask what the benefits are for one over the other. With a 2 door unit, you can close the doors down to zero opening but the opening will always be a long slit. This is not a bad thing but under certain circumstances it is more convenient to have 4 doors so you can close down in both axis at the same time keeping your light source symmetrical. The bottom line is that if you have a 4 door unit, you also have a 2 door. Just doníŽt use the other two.
The benefits from using barn doors are not as well known as with other studio toys. Today we have such a huge emphasis on technology doing everything for us that many simple devices like the barn doors are sadly all but forgotten. Barn doors provide control unlike any other device. With nothing more than a quick flip of the hand, you can change the amount of light exiting your flash unit from 100% to 0 % or any increment in-between those extremes. The beauty of this is that the changes made affect both modeling light and strobe tube equally so you can stay in a "what you get is what you see" mode.
Flash heads, whether hooked up to a power pack or integrated into a moonlight, generally feature an interchangeable reflector (bowl or dish) used to shape the light. Interchangeable reflectors give photographers numerous options. For one, bare-bulb photography, which produces an even light around the entire room, reminiscent of sunlight. Certain reflectors are designed to accommodate a photographic umbrella, whereas many heads require an accessory replacement dish for this purpose. The shape of the bowl and its finish also determine the throw of the light and its quality.
Color filters :
Color filters for your strobes light will add a whole new dimension to your creative. Imagine the possibilities as you are able to change the color of your lights casting mood and atmosphere into everyday scenes. Color filters can be placed directly on the head units or combined with barn doors for further versatility.
