How to use Ro­to­light’s colour tem­per­a­ture con­trols cre­atively

1 Am­bi­ent light

Make sure there is enough am­bi­ent light to regis­ter with your cam­era’s set­tings. This is the light you will be ma­nip­u­lat­ing. The over­all scene will be slightly il­lu­mi­nated by it. This is your can­vas, if you like, on which you will light your sub­ject.

2 Sub­ject light­ing

Make sure the am­bi­ent light does not overly light your sub­ject, to avoid tak­ing on the colour you are try­ing to achieve in the set­ting. Here the lights are un­changed at around 5000K and there is a gen­eral neu­tral or blue hue to the scene. The rim light is hid­den be­hind the pil­lar.

3 Warm or cool?

De­cide whether you want the am­bi­ent light to regis­ter as cool or warm. If you are us­ing gels you can use the same prin­ci­ple with other colours and their op­po­sites. For ex­am­ple, bal­anc­ing for a ma­genta key light will make other light(s) go green.

4 Tem­per­a­ture con­trols

Dial in the op­po­site tem­per­a­ture to what you would like as am­bi­ent. For a warm back­ground, set the tem­per­a­ture to some­thing cooler than day­light (which is around 5500K) like 6300K. To set, press the right hand con­trol and the dis­play will change from out­put to tem­per­a­ture.

5 White bal­ance

Set the white bal­ance on your cam­era to the same as your key light us­ing white pa­per not lit by the am­bi­ent light. The sub­ject is lit with the max­i­mum colour tem­per­a­ture of 6300K. When this is bal­anced in- cam­era to day­light (5500K to 6000K) the am­bi­ent will be warmer.

It was a joy us­ing a por­ta­ble light source straight out of the bag with­out hav­ing to con­struct a soft­box Fu­ji­film GFX 50S, 32-64mm, 1/30sec at f/5.6, ISO 1250
