Studio lighting and extension tubes



The Esprint 500
There are many different models of the Bowens studio flash heads. The Esprint
500 series gives full control over the lights intensity, and allows you to control both
the modelling lamp and flash tube.

    Health and safety


    The ring flash shown here and the modelling lamp is made of very 
    fine glass that can cause painful glass splinters if broken. 
    • Do not touch the bulbs at any time, especially after use, as they will be hot.
    • Do not knock the bulbs when fixing light accessories to the unit.
    • Do not put the protective plastic cap over the bulbs until they have 
    cooled. Leave the light accessory in place until ready.
    • Do not leave lights on when not in use

    It is important to keep your work area safe
    • Leads should be kept tidy and either taped to the floor or covered 
    with rubber mats
    • Do not leave coats and bags on the floor
    • Do not set your equipment up by a door way or in front of a fire exit
    • Act responsibly when around expensive and fragile equipment.

    Extension tubes
    Extension tubes are used for close up, macro work. They
    generally come in three different sizes; 12/13mm, 20/21mm & 
    31/36mm (note the sizes may change depending on the 
    make). One or a combination of extensions increase the 
    magnification of the lens and are attached to the camera in 
    between the camera body and the lens itself.


    Own images using extension tubes: 

    When using extension tubes you need to set the focus ring on your lens to
    infinity. To focus your image you will physically have to move the camera closer or
    further away from the subject. You should also set your lens to a small aperture

    (f/16) and adjust the lighting units accordingly until you get the correct reading,
    remember the table above. Example: if you are setting your camera to f/16 and you
    are using a 31mm extension, you need to make your lighting brighter until your light
    meter is reading f/22.5 (f27)




    1. High-key lighting is a style of lighting for film, television, or photography that aims to reduce the lighting ratio present in the scene. This was originally done partly for technological reasons, since early film and television did not deal well with high contrast ratios, but now is used to suggest an upbeat mood.
      1. Low-key lighting is a style of lighting for photography, film or television. It is a necessary element in creating a chiaroscuro effect. Traditional photographic lighting, three-point lighting uses akey light, a fill light, and a back light for illumination.
