2. Photoflash capacitor - Wikipedia

   en.wikipedia.org/wiki/Photoflash_capacitor

   The light energy emitted by a flash is supplied by the capacitor, and is proportional to the product of the capacitance and the voltage squared; photoflash capacitors may have capacitance in the range 80-240 microfarads (μF) and voltages from 180 to 330 volts for flash units built into small disposable and compact cameras, increasing for units ...

3. Photographic lighting - Wikipedia

   en.wikipedia.org/wiki/Photographic_lighting

   Photographic lighting refers to how a light source, artificial or natural, illuminates the scene or subject that is photographed; put simply, it is lighting in regards to photography. Photographers can manipulate the positioning and the quality of a light source to create visual effects , potentially changing aspects of the photograph such as ...

4. High-intensity discharge lamp - Wikipedia

   en.wikipedia.org/wiki/High-intensity_discharge_lamp

   Brand new high-intensity discharge lamps make more visible light per unit of electric power consumed than fluorescent and incandescent lamps, since a greater proportion of their radiation is visible light in contrast to infrared. However, the lumen output of HID lighting can deteriorate by up to 70% over 10,000 burning hours.

5. Flash (photography) - Wikipedia

   en.wikipedia.org/wiki/Flash_(photography)

   A full-power flash from a modern built-in or hot shoe mounted electronic flash has a typical duration of about 1ms, or a little less, so the minimum possible exposure time for even exposure across the sensor with a full-power flash is about 2.4 ms + 1.0 ms = 3.4 ms, corresponding to a shutter speed of about 1 ⁄ 290 s. However some time is ...

6. Three-point lighting - Wikipedia

   en.wikipedia.org/wiki/Three-point_lighting

   Three-point lighting is a standard method used in visual media such as theatre, video, film, still photography, computer-generated imagery and 3D computer graphics. [1] By using three separate positions, the photographer can illuminate the shot's subject (such as a person) however desired, while also controlling (or eliminating) the shading and ...

7. Reflector (photography) - Wikipedia

   en.wikipedia.org/wiki/Reflector_(photography)

   A portable folding reflector positioned to "bounce" sunlight onto a model. Reflectors vary enormously in size, colour, reflectivity and portability. In tabletop still life photography, small mirrors and card stock are used extensively, both to reduce lighting contrast and create highlights on reflective subjects such as glassware and jewelry.

8. Ring flash - Wikipedia

   en.wikipedia.org/wiki/Ring_flash

   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. [5] Light is usually generated by one or more flash tubes or by multiple LEDs. In some flash units with multiple flash tubes, each flash tube can ...

9. Pantograph (lighting suspension) - Wikipedia

   en.wikipedia.org/wiki/Pantograph_(lighting...

   A pantograph is a commonly used overhead suspension system for lamps and audio and video monitors in television studios. It is also used on a smaller scale in many photography studios. Using either motor driven cables or a spring system, the pantograph can be balanced so that a light touch can readjust the height of the load (usually a lamp ...
