Frequently, different operating modes are required in order to capture every moment perfectly.The Rollei flash devices are prepared for every moment.These flash devices can also be operatedmanually.In this way, you can determine the power, zoom, exposure time, aperture and the ISO value.You can use other modes as follows:
- Master/slave operation:for the use of several flash devices and synchronized release of these flash devices
- Flash bracketing:for times when a picture must be produced and there is no time left for examination
- Stroboscope flash operation:for the exposure of a moving object in different phases
- Synchronisation on the 1st and 2nd shutter
Photos from afar - Rollei flash devices with an integrated wireless receiver
In order to make so-called uncontrolled flash photography possible, one or more flash devices, which are physically separate from the camera, are needed.In the process, the connection to the Rollei flash device can be made in several ways: wirelessly, by means of a cable connection or via a control unit.
The new wireless flash devices from Rollei are available with the guide numbers 56 and 58 for Nikon/Canon cameras. Owners of Sony models work with the specially developed 56 wireless flash device.The receiver is already integrated into the housing. The associated transmitter is simply put on the flash shoe of your camera.
- Wireless-controlled flashing on 16 channels
- A 50-metre range in internal spaces and in the open air
- Synchronisation on the 1st or 2nd shutter
Flashes - the right light for the perfect moment
Photography is painting with light. The sun, artificial continuous light or flash devices serve as sources of light.However, Rollei flash devices can do far more, than merely ensure that lighting is provided at the right time.They offer you innumerable possibilities for creative light design.
If you use flash on a reflecting surface indirectly, you can illuminate the subject more softly and can include the dimensions of an area even better. Back lit photographs are only possible if the primary light comes from the rear and highlights the outlines. Conjure up individual lighting ambiences it with external, interconnected flash devices.Today, with the right equipment, “uncontrolled” flash photography is as flexible and simple as never before.
What dealing with flash devices is all about
Modern, digitally controlled and wirelessly synchronised flash devices relieve you not only of the great amount of adjustment work they also offer you sophisticated functions in order to be able to bring your photographic creativity to life.Nevertheless, you shouldn’t lose sight of a couple of aspects:
When you use flash indirectly, the greater the reflection surface the softer the light becomes. With this knowledge, you can affect the contrasts in the picture in a targeted way.
If you flash the subject directly, the result usually turns out rather flat.This is because of the proximity of the flash to the lens.The further you remove the flash device from the optical axis of the camera, the more delineation and contrast you obtain.Naturally you can also use the frontal flash completely consciously to lend a snapshot look to your picture.
You can vary the depth of field to photograph all subject levels with the same degree of sharpness. However, when you are flashing you will notice that the lighting effect decreases in proportion to the distance.To compensate for this, indirect flashing or simply using the flash device in a position that is still further away will help.For example, the reduction of brightness makes a significant difference at a distance of between 2 and 3 metres but is no longer that considerable at a distance of between 7 and 8 metres from the subject.
