Tiffen International is showing its latest developments in optical filters, location lighting and camera support at Broadcast Video Expo. Product demonstrations include Steadicam working with popular DSLR video cameras.
Steadicam DSLR Hands-on
The combination of Steadicam and DSLR video enables shooting smooth handheld 'walkabout' HD material with the economy, small size and light weight of a go-anywhere DSLR rig. Two Steadicam models cover the needs according to the weight of the rig. The Merlin arm supports up to 2.3 kg – and up to 3.4 kg when used with a vest. Beyond that Pilot is available for the fully loaded rigs weighing up 4.5 kg. BVE provides the opportunity for hands-on trials to discover how the Steadicam/ DSLR combination can produce professional results with natural human-eye looking movement.
Lowel Blender Light
Tiffen is also showing its new Lowel Blender LED light that can provide daylight, tungsten and mixtures in-between to deliver colour-matched light for a variety of location video needs, without using gels. The light source has twin arrays of high CRI (Color Rendering Index) LEDs to produce light that allows crisp and more naturally coloured pictures. Two rotary controls on the back of the lamphead provide continuous individual adjustment of the daylight and tungsten LED intensities to blend the overall output colour so that shots look naturally lit. The compact size, weight of only 550 grams and ability to run from 7.2-15 VDC batteries, or via an AC power adaptor, make the Lowel Blender LED light easy to carry as a part of the camera kit.
TI IR filters
The range of new TI IR filters, manufactured to remove the infrared light that can affect cameras using CMOS and CCD image sensors, are on show. These are manufactured to Tiffen's established high standards to effectively eliminate IR pollution and, only having a half-stop of attenuation, can be used as fix-and-forget extras. They allow cameras to capture the full range of subtle red hues while maintaining crisp blacks and the entire wide colour gamut the cameras were designed for. They contain no dichroic coating and so will not vignette green, magenta or cyan at wide angles and are available in 77mm (thin profile wide-angle ring), 138mm, 4x4, 4x5.65 and 6.6x6.6 with other sizes supplied on request. T1 IR filter performance tests with Sony EX1 and EX3 digital video cameras show the IR pollution that can appear on the cameras' output are not seen when using the filter.
Dfx V2 filter software
Aside from its optical filters Tiffen is also showing the V2 version of its Dfx software that offers digital representations of its glass optical filters for use with digital images. It provides pre-visualisation of specifically named, trademarked filters using terminology that refers to physical cinematography and photography in a software suite. Over 2000 filters and presets are provided in the full Dfx software. These include a whole range of colour temperature filters and many effects filters as well as graduated, polarising, enhancing filters. There are also spectral matches of lighting gels as colour layers. This can be used for pre-visualisation or altering the colour of a shot scene. Dfx is designed to be easy to use.
Dfx is offered free as a trial version download from www.tiffen.com. The ful version is also available at the site. Other versions are supplied as plug-ins for Photoshop and for Aperture, and editing plug-ins for Final Cut Pro, After Effects and Avid. iPhone photographers might like to try the 'Photo fx' and 'Cool fx' apps for in-phone 'filtering' of pictures.
