In addition, other angled faces may be formed at other intersections or other locations on the body 52 , such as intersections of the front face 58 and the top face 62 , the front face 58 and the bottom face 64 , the rear face 60 and the first or second side faces 66 , 68 , or combinations thereof, such as the front, bottom, and second side faces 58 , 64 , and While the angled faces are one means for redirecting light within the diffuser body 52 , other means may be used.
For example, as shown in FIGS. The diffusing element 72 allows a portion of light from the flash unit 20 to pass therethrough while the remaining light is reflected into the diffuser body 52 for distribution around the central opening 54 and out the front face While the diffuser body 52 is generally symmetrical with respect to the opening 54 , it can be seen that the top face 62 angles downward towards the front face 58 from the rear face 60 , terminating at an intersection 61 above the opening 54 , while the bottom face 64 angles downward from the rear face 60 to the front face This is more clearly shown in FIG.
The diffusing element 72 also extends a portion of the way down the front face 58 of the diffuser body 52 , as shown in FIG.

In one embodiment, the diffusing element 72 is constructed of paper, ideally white paper, although other materials that are readily commercially available may be used for providing a similar effect. A portion of the light passes through the filter element 72 and the diffuser body 52 to exit the front face Another portion of the light is reflected off the top face 62 throughout the diffuser body 52 , some of which reflects off the rear face 60 and the first and second side faces 66 , 68 to exit through the front face 58 around the opening More of the light continues through the diffuser body 52 to reflect off the bottom face 64 and out through the front face 58 below the opening 54 and the camera lens Thus, the bright flash of light is redirected and distributed throughout the diffuser body 52 to exit around the opening 54 and the camera lens 14 to illuminate a subject In order to retain the diffuser 50 on the lens 14 , various means may be used, including an elastomeric or flexible grommet or lining around the opening 54 , mechanical means, such as set screws and the like, or a tongue and groove arrangement where the diffuser body 52 matches external configurations on the lens 14 to prevent rotation of the diffuser body 52 with respect to the lens In other embodiments, however, it may be desirable to allow the prism body 52 to rotate relative to the lens to provide or enable adjustment in the direction of light exiting from the diffuser Attachments can also be used in conjunction with the diffuser 50 , such as a magnifier to be placed in front of the lens The magnifier can be attached to the diffuser 50 and configured to be lowered over the lens 14 or raised away from the lens 14 and the front face 58 of the diffuser The magnifier can be clipped on or permanently mounted to the diffuser or, less preferably, to the camera.
Color filters and other accessories may also be used in this manner.
The diffuser 50 can also be implemented for use with an active flash that is either slaved to the camera flash or triggered by the camera. The diffuser could also be implemented with a modular light source as an aid in focusing of the camera or as main illumination for the photograph. While a preferred embodiment of the invention has been illustrated and described, it is to be understood that various changes may be made therein without departing from the spirit and scope of the invention.

For example, the diffuser body 52 may be configured to redirect light by any method, including reflection, refraction, scattering, selective attenuation or concentration of the incoming light. Various configurations in the shape of the diffuser 52 may be used, including round, or round with enlarged sides, or various geometric shapes including square, rectangular, pentagonal, hexagonal, octagonal, or a combination of rounded and straight sides.
In addition, the diffuser 50 can be hollow with internally-mounted or formed reflectors. Also, light pipes or other light conductors may be used for redirecting and redistributing the light. Hence, the present invention is not to be limited except by the accompanying claims and the equivalence thereof. All of the above U. From the foregoing it will be appreciated that, although specific embodiments of the invention have been described herein for purposes of illustration, various modifications may be made without deviating from the spirit and scope of the invention.
Accordingly, the invention is not limited except as by the appended claims. A device for distributing light, comprising: a body having a central opening formed therein, means for receiving light from a first side of the body, and means for redirecting light around the central opening to exit a second side of the body.
The device of claim 1 wherein the body comprises a prism. The device of claim 2 wherein the light redirecting means comprises a plurality of faces for redirecting light within the prism and a diffuser element to diffuse at least a portion of the light exiting the prism.

A device for distributing light to be used in conjunction with a camera having a lens and a flash, the device comprising: a body having a central opening sized and shaped to be received over the lens of the camera, the body having a first side configured to receive light from the flash, and means for redirecting the light from the first side of the body to exit a second side of the body around the central opening.
The device of claim 4 wherein the body comprises a prism and the light redirecting means comprises a plurality of faces formed on the prism. The device of claim 5 , further comprising a diffuser element to diffuse at least a portion of the light exiting the prism. A camera flash diffuser, comprising: a body having an annular configuration defining a central aperture sized and shaped to be received over a lens associated with the camera, the body comprising a first side for receiving light from the camera flash, means for redirecting light within the body, and a second side through which the light exits.
The device of claim 7 wherein the body comprises a prism and the light redirecting means comprises a plurality of faces formed on the prism. The device of claim 8 , further comprising a diffuser element to diffuse at least a portion of the light exiting the prism. This book is not yet featured on Listopia. Community Reviews.

The way to avoid this is to use diffusers, which spread out the light across a bigger surface area. This results in a softer light that looks natural and makes your macro photographs aesthetically more pleasing. Diffusers can be made out of materials found in the home; tissue paper is great for example. This image was taken with no diffuser, notice how the light is quite harsh and reflects off the subject.
This is the same subject, but captured using a diffuser. Notice how the light looks much more natural and makes the image look more appealing.
Adding coloured lighting to macro photos can make them unique, and stand out in the crowd. You can do this by applying gels or colour filters to your lighting equipment. This image of shaving foam has been captured using coloured continuous lighting. This image of a flower has been captured using coloured continuous lighting.
Understanding how the direction of light alters the appearance of your subject is significant. This is much easier to do with continuous light, although it can be done with flash as well.
