Ranger RX Lighting Kit
The Ranger RX is a portable lighting kit that can be taken anywhere as it has a battery and does not need an external power source (does not need to plugged in). The battery life of the RX kit is around 6 hours and it is always a good idea to take two batteries so the shoot is not cut off. It produces 1100 watts, compared to a studio kit which will only produce 150. Skyports do not work with these lighting kits so a sync lead or infrared trigger will be needed. Unlike the studio kits these do not have controls on the back of each light so you have to be practical about how to direct the light.
When taking light meter readings you will need to cover each light individually to get an accurate reading for both lights. They have modelling lamps like the studio kits, however they only stay on for 15-30 seconds in order to conserve energy. Like most flash lighting kits the shutter speed you need to use is 125th of a second and it is best to use the lowest ISO possible to maximise detail.

The pros. and cons. of using the Ranger RX Lighting kit:
Pros:
- Accessibility
- Takes all standard Elinchrom fittings, i.e. soft box etc.
- Convenience, it has a battery.
Cons:
- The weight, 15kg approximately
- Battery, needs to be charged fully, charging time is very long (12 hours approximately)
- The length of the leads are not very long so movement is limited.
Fill-Flash:
Fill-Flash can be used for a range of things, such as;
- To compliment existing ambient light
- To bring out detail in shadow areas
- To highlight subject from background
It can also be used to capture movement by repeating the flash while the subject moves during a long exposure as the flash freezes the movement. Another technique that creates some clever effects is 'Rear Curtain Sync'. How to achieve this is by setting your camera to have a shutter speed of 1 second then right near the end the flash will fire.
The way in which to change the exposure when using flash are as follows:
- Distance from subject, the smallest movement in and out can change your exposure a lot
- Diffusion, bounce
- Soft Boxes
- Reflectors
- Aperture
- Power Output
On a SB-800 flash gun you have a series of modes:
- TTL - Through The Lens, standard exposure.
- A/AA - Aperture Priority
- M - Manual
- BL - Balanced Light
If you need to move the flash gun around to get the light source from a different angle you can use a curly wulry which will allow you to control the flash gun with your hand while you take the picture.
Simulating light is a technique you can create with the use of a flash gun that allows you to create a night/dusk effect using a combination of shutter speed and fill-flash and using a small aperture to 'subdue' the ambient light, thus making the subject more defined within the photograph.
