The Basics of Photographic Flash

By Stephen Spreadbury


Excellent photographic studio flash systems are dissimilar from on-camera flashes in many ways. As well as providing considerably more flashpower, studio strobes are engineered to be used with a wide variety of light shaping accessories such as umbrellas, softboxes, grid spot attachments, barndoors, beauty dishes and other modifiers. All of these accessories offers a different quality of lighting, allowing the photographer to precisely create the light to suit his vision.

Studio flash units in several cases are employed in multiples, with as many as four or maybe more lights often employed to obtain intricate combinations of studio light and shadow. The range of setups involving studio lights demands the user run away from Automatic Exposure Settings within the camera. Cameras must be set to Manual Mode with aperture and exposure time set by hand. The power levels can be adjusted on each light separately in order to compose the scene, and a flashmeter is mostly employed to pinpoint the ideal camera lens aperture setting.

Modeling Lamps are used by the digital paparazzo so that you can see what the scene will look like if your picture is taken, studio flash units feature Modeling Lamps. They're incandescent lamps of modest power that are put from the studio flash in this position as to replicate light which may be emitted from the flash once the actual picture is taken.

It is highly important that your studio flash utilise a acceptable power array for your location and subject or product matter. We would suggest 160 WS to 320 WS units for the littler studios and location shooting and 640 WS units for much bigger studios. If your strobes are too strong you may struggle to open your cameras aperature wide enough to get a narrow depth of field to cloud your backgrounds.

Strobes and photographic modifyers can be superb tools when used correctly by a professional paparazzo.
