The majority of consumer cameras have this type of flash built in. </p> <h3 data-rte-empty-lines-before="1">Microflash</h3> <p data-rte-fromparser="true">"Microflashes" are high-voltage flash units designed to discharge a flash of light with an exceptionally quick, sub-microsecond duration. These are commonly used in scientific photography for examining extremely fast moving objects or reactions, famous for producing images such as bullets tearing through balloons. </p> <h3 data-rte-empty-lines-before="1">Magnesium powder flash</h3> <p data-rte-fromparser="true">The earliest flashes consisted of a wad of magnesium powder that was ignited by hand.

A fill flash is a low powered flash mixed with ambient light, and is often used to illuminate shadows on the side of a subject facing the camera. Another technique, bouncing a flash, involves pointing a flash upwards off of a surface, often a white celling, where it is reflected back onto the subject. Bouncing creates a more natural light effect and lessens shadows and glare but requires more flash power than a direct flash. </p> <h2 data-rte-empty-lines-before="1">List of camera flashes</h2> <ul><li>(add yours here) </li></ul> <h2 data-rte-empty-lines-before="1">Links</h2> <ul><li data-rte-spaces-before="1"><a data-rte-meta="%7B%22type%22%3A%22external%22%2C%22text%22%3A%22Flash%20Photography%20with%20Canon%20EOS%20Cameras%22%2C%22link%22%3A%22http%3A%5C%2F%5C%2Fphotonotes.org%5C%2Farticles%5C%2Feos-flash%5C%2F%22%2C%22linktype%22%3A%22text%22%2C%22wasblank%22%3Afalse%2C%22wikitext%22%3A%22%5Bhttp%3A%5C%2F%5C%2Fphotonotes.org%5C%2Farticles%5C%2Feos-flash%5C%2F%20Flash%20Photography%20with%20Canon%20EOS%20Cameras%5D%22%7D" data-rte-instance="1108-12410444845def840e76b72" rel="nofollow" class="external text" href="http://photonotes.org/articles/eos-flash/">Flash Photography with Canon EOS Cameras</a> </li><li><span class="placeholder placeholder-double-brackets" data-rte-instance="1108-12410444845def840e76b72" data-rte-meta="%7B%22type%22%3A%22double-brackets%22%2C%22wikitext%22%3A%22%7B%7BWikipedia%7CFlash_%28photography%29%7D%7D%22%2C%22lineStart%22%3A%22%22%2C%22title%22%3A%22Wikipedia%22%2C%22placeholder%22%3A1%7D" contenteditable="false">​​</span> </li></ul> <p /> <!-- Saved in parser cache with key photography:rte-parser-cache:1354 --> Loading editor Equipment Below are some commonly used wiki markup codes.
