ring flash การใช้

• I'm looking into getting a ring flash for my Canon EOS Digital Rebel.
• Canon also produced a dedicated macro ring flash for the camera, the ML-2.
• Other devices are available that project light in a fashion similar to ring flashes.
• The later ML-3 ring flash, introduced for the EOS system cameras, also supports the T90.
• Dynalite uses Niven's work to advertise their lightweight studio lighting, " road series " and ring flash units.
• Some ring flashes have focusing lenses that result in ideal light distribution at a particular distance from the subject.
• Some young photographers today, like Juergin Teller and Nick Knight, use a ring flash to create a similar effect.
• Some other passive light modifiers can shape the light from a conventional shoe-mounted flash into that of a ring flash.
• Ring flashes, with flash tubes arranged in a circle around the front of the lens, can be helpful in lighting at close distances.
• Ring flashes are also popular in portrait and fashion photography because they soften the shadows created by other, off-axis lights, and create interesting circular highlights in a model's eyes.
• A macro ring flash typically consists of a power and control unit mounted on a hot shoe, and a circular flash unit mounted on the front of a lens.
• Parr's aesthetic is close-up, through use of a macro lens, and employing saturated colour, a result of either the type of film and / or use of a ring flash.
• Ring lights have emerged, using white LEDs to provide a continuous light source for macro photography, however they are not as bright as a ring flash and the white balance is very cool.
• In larger ring flashes, which are typically used for fashion photography, power may be supplied by an external battery or line power supply, or the power supply and light may be combined in one unit.
• The maximum 0.5x magnification means this lens is more suitable for photographing documents, products and objects at least 5cm ( 2 inches ) wide than small insects etc . The outer barrel is grooved to accept Canon's MR-14 ring flash which can be used as the principal light source for close-ups or as on-axis diaphragm provides reasonably good out-of-focus blur ( bokeh ) for portrait work.
