1. For example using the 500 watt EHC lamp in the Rifa eX 55 at a distance of 5 feet will give you 72 foot candles of light with the amount of softness from a 24 square inch source yet using the same 500 watt EHC lamp in the Rifa 88 from a distance of 5 feet will give you the aprox the same 72 foot candles of light yet a greater amount of softness because its now coming from a larger 32 square inch source The TH X300 Accessory Lamphead can quick ly swap to allow greater use of lower wattage lamps in larger sized Rifa s to reduce output while retaining softness It is the supplied standard lamphead for Rifa eX 44 Postitioning the Rifa Soft light falls off in output strength much more quickly than a hard source of identical wattage because the soft source is so much larger in size light is dispersed in a wider direction As a result soft sources like Rifa are designed to be used fairly close to the sub ject This can create problems of light spill on the areas behind the subject The first step in minimizing background spill is to move the subject away from walls by 6 feet or so if pos sible This will allow a light placed on a stand higher than the subject to fall off towards the floor before hitting the wall Using Fabric Egg Crates Another situation that can arise as a result of using soft sources close to the subject is fl tuation in exposure level that can occur if the subject moves ba2. OY The second option involves using some level of daylight color correction gel The goal is to match the warmer 3200k tungsten lamp in the Rifa with the cooler daylight color 5000 6500k Because daylight can vary in color depending on whether its direct sun overcast clouds blue sky or any combination of the above you will need to choose either 1 4 1 2 or full day blue to most closely match the Rifa to the daylight in the room Rifa Day Blue Gels are custom cut to fit the Rifa s They are sized to cover the front diffuser with enough excess to allow them to be clipped to the velcro pock ets on the side of the light You can use clothespins Lowel Gel jawz or any small spring loaded clip These are just some starting suggestions For an in depth understanding of the creative decisions involved in the art of lighting we suggest a visit to Lowel s EDU section at lowel com You will find an in depth lesson on using the eXchange lamp heads of Rifa eX Learn to Light Better JOWEIEDU A LIGHTING RESOURCE CENTER Basic Starter Setups using Rifa eX Setup 1 A Camera 1 Rifa 1 Tota light To light an interview subject with the Rifa eX alone You can place the light at a 45 angle 2 3 feet higher than the subject with the light tilted down towards the subject From there you can arc the angle of the rom 6 00 at camera this will give the most even lighting to either 3 00
