To offer a real 3D experience, the W3 uses dual lenses, placed 64mm apart, to simulate the distance between our eyes. These images are captured on two separate 1/2.3in, 10MP CCD sensors and the 3D HD RP (real photo) processor then combines this information to produce MPO-type 3D still images or a 3D AVI file.
The W3 can also be used as a standard 2D compact camera and, even when in 3D mode, it will also record by default a JPEG image alongside the 3D file. Still images are output at a standard 10MP size of 3648×2736 pixels for both 2D and 3D images, with 4:3 and 16:9 options also available, and at 1080×720 pixels for video.
The lenses offer a 35mm equivalent of 35-105mm focal length with a maximum aperture of f/3.7-4.2. This gives a decent range for standard scenes and portraits – the wideangle abilities are limited by the use of the dual lenses. Similarly, close focus is just 38cm in 3D mode but 8cm in 2D. The ISO offers a range of 100-1600 with three auto settings to limit it to either ISO 400, 800, or 1600. Metering offers a choice of average, spot and multi, with ±2EV exposure compensation.
There is a choice of fully manual, aperture priority and program shooting modes, along with full auto, two sets of scene modes and advanced 2D and 3D settings.
The advanced 2D settings allow you to use each lens to provide two alternate shots at once; this includes a wideangle and telephoto combination, a choice of two colour settings and two ISO sensitivities.
The advanced 3D modes allow you to move the camera between the two shots being taken, to allow you to widen the distance. This increases the perceived 3D effect for distant subjects or allows you to get closer for macro shots. This can be done with a timed interval between the shots or by pressing the shutter twice.
When shooting in 3D, the autofocus will, by default, automatically set the parallax control of the two lenses to determine the extent of the 3D effect. This can also be fine-tuned with a rocker on the top of the camera.
The rear LCD screen on the W3 is lenticular in its design, which means it will display an apparent 3D image without the need for any special glasses. Compared to the screen on the W1, this new 3.5in display is larger and the viewing angle has been improved, making it easier to see the 3D effect..
