How to mount Rotolight on your Shotgun Mic
How to mount Rotolight using the Rotolight Stand
Align the centre hole of your Rotolight over the foam windshield of your Camcorder Microphone and
carefully slide the Rotolight over the foam windshield.
Fit the accessory shoe to 1/4” thread adapter to the accessory or ‘hot’ shoe on your camera. Tighten the
lower thread of the shoe adapter down onto the shoe. Attach the support arm to the shoe adapter and
secure it facing forward by tightening the upper thread tensioner of the accessory shoe. Put the Red Boss
assembly through the centrehole of the RL48-B and clip the legs into the holes of the support arm.
To remove Rotolight, pinch the back of the microphone foam windshield with your left hand and with
your right hand carefully slide the Rotolight o the mic to the front.
To release, gently squeeze the legs together at the rear of the support arm whilst holding the Rotolight
and Logo boss assembly (take care not to let the Logo Boss pop out of the front hole).
Rotolight Stand can also mount onto tripods, suction mounts, 360° Swivels, Lighting Stands, etc.
Colour temperature is a standard meth-
od of describing colours for use in a
range of situations and with dierent
equipment.
Colour temperatures are normally ex-
pressed in units called ‘degrees’ Kelvin
(K). This scale is used to describe a visi-
ble light colour , and was based on heat-
ing a black object up until it glowed at
a precise colour, hence ‘degrees’ Kelvin.
Modern digital photographic and video
cameras can adjust the ‘white balance’of
their image capture system mimicking
the way that the Human eye perceives
colour. This process allows the camera
to accurately capture the colours as the
eye sees them.
Filters, Colour Temperature
and ‘White Balance’
Most common lighting conditions produce light in the temperature range from around 2,000K to 8,000K.
In practical terms this usually means selecting lights, gels and lters which are most appropriate to the
prevailing light or to create a particular colour eect.
For example, a camera operator will select a “3200K lter” to use for an interior shot when the prevail-
ing ambient light is from tungsten bulbs. Ideally you want all the elements in your image illuminated at
roughly the same colour temperature, otherwise dierent parts of the picture may have a blue or orange
tint.
The human eye can detect a colour dierence of 100 Kelvin, so you’ll be pleased to know that Rotolight
is ‘Studio Accurate’ (i.e. to within +/- 50 kelvin of its calibrated colour temperatures)
Using the Colour Correction and Calibration lters
Rotolight RL48-B ships with 7 special ringlight calibration lters which are stored inside the Rotolight and
t into the Filter Holder. These are used for colour correction, dimming, minus green and diusion, which
allow you to accurately match Rotolight to the ambient light colour
temperature. Please refer to the Calibration Chart inside the Rotolight
RL48-B for more information on which lters to use for desired eect.
Included Colour Correction, Dimming and Diusion
Filters :
218 - 1/8th CTB (Direct Daylight)
205 - 1/2 CTO (Mixed)
LED 204 - 15/16ths CTO (Tungsten)
216 - Diusion Filter
209 - Neutral Density (Reduces light 1 stop)
298 - Neutral Density (Reduces light 1/2 stop)
279 - 1/8 Minus Green (Magenta)
To t the lter holder, simply hold it in your left hand with the open side facing upwards and push the
Rotolight (face down) into the centre of the lter holder. To remove it, place your thumb in the middle of
the front face of the Rotolight (near the ON switch) and use your other ngers to lift the outer edge of the
lterholder away from the face of the Rotolight.
To turn the unit on, simply press the switch in the front of the Rotolight RL48-B.
