Lighting Diagram and Suggestions

Good lighting is the key to great images. Use multiple Rotolights to quickly create the perfect lighting solution for your location or studio needs.

The Rotolight RL48-B LED Ring Light gives you the possibility of having a front-facing, camera mounted ‘keylight’ on your subject, and, then using a second Rotolight with perhaps a creative Colour FX filter, mounted on a spare tripod as a kicker/backlight/sidelight or toplight. This is called ‘2-point lighting’ and will considerably improve the dramatic impact, separation and presence for your subject.

Add-On Colour FX Filter Kit Guide

Rotolight ‘Add-on Colour FX Filter Kit’ features 10 of the most popular LEE Lighting colour filter gels, comprising eight Colour FX filters for sidelight, backlight, kicker or top light and two cosmetic filters for
skin tone enhancement.
The Rotolight Add-On Colour FX Filter gels have been created by some of the World’s leading lighting designers working in Stage, Screen, Cinema and Television to capture specific moods or colour effects,
and the result is a superb collection designed to compliment most common lighting conditions.

Specifications:

Using the filter holder

To fit the filter 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 filter 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 fingers to lift the outer edge of the filterholder away from the face of the Rotolight.

How to mount Rotolight on your Shotgun Mic

Align the centre hole of your Rotolight over the foam windshield of your Camcorder Microphone and  carefully slide the Rotolight over the foam windshield.

To remove Rotolight, pinch the back of the microphone foam windshield with your left hand and with
your right hand carefully slide the Rotolight off the mic to the front.

How to mount Rotolight using the Rotolight Stand

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 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.

Filters, Colour Temperature and ‘White Balance’

Colour temperature is a standard method of describing colours for use in a range of situations and with different equipment.
Colour temperatures are normally expressed in units called ‘degrees’ Kelvin (K). This scale is used to describe a visible light colour , and was based on heating 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  heir 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 filters which are most appropriate to the prevailing light or to create a particular colour effect. For example, a camera operator will select a “3200K filter” to use for an interior shot when the prevailing ambient light is from tungsten bulbs. Ideally you want all the elements in your image illuminated at roughly the same colour temperature, otherwise different parts of the picture may have a blue or orange tint.
The human eye can detect a colour difference 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 filters

Rotolight RL48-B ships with 7 special ringlight calibration filters which are stored inside the Rotolight and fit into the Filter Holder. These are used for colour correction, dimming, minus green and diffusion, 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 filters to use for desired effect.
