Every once in a while we
come across a new accessory and software from other manufacturers that can
greatly enhance the versatility of Leica equipment. One such accessory is the LensTRUE System by
JOBO. It promises an alternative to adjustable
cameras and offers technically perfect images without distortion and
vignetting. The Lens TRUE System is accompanied
by the Lens TRUE System M, designed for medium format digital cameras.
Every photographer knows
the problem of perspective distortion. Modern image manipulation software
allows some corrections but in most cases these corrections are cumbersome and
time-consuming. They still render wrong proportions as all these corrections
are made only by hand and rely on visual approximation. Even with Photoshop’s
“perspective control” features the most you can achieve is rendering that is
only similar to the real proportions.
Unlike the equalization or
correction of perspectively distorted image with the use of mechanical shifts
or conventional image editing software the LensTRUE system solves the problem
by combining hardware and software.
The LensTRUE System
consists of an electronic inclinometer (LensTRUE meter) to measure and register
the angular position. In a second step the RAW files are combined with the
meter data in the correction software (LensTRUE final) and descewed automatically
in both levels. Even photographs without reference lines and without
perpendicular objects are corrected to the real proportions even when the horizon is not aligned.
The prerequisite for the
use of LensTRUE is a sensor resolution of eight megapixels. However, the higher
the sensor resolution, the more the camera can be angled. The limit of the
automatic correction with LensTrue is 35 degrees. In practice, the inclinometer
is mounted on a tripod and connected to the camera. The inclinometer records
the data of the camera position in every shot. The LensTRUE Software writes the
information gained in the metadata of the image file and uses it for the
perspective correction. The image information is automatically corrected,
however, the correction by LensTRUE leads to a change of the image format.
In a sense LensTRUE
transforms all your lenses into shift lenses – even the zoom lenses! This means
you can use any focal length and you can shoot without a tripod – and still
attain proportionally correct images formerly only achieved by using special
Tilt & Shift Lenses. The LEICA S6 is
already profiled with the most important lenses. Soon Leica S007 and Leica SL will follow.
LensTRUE opens up a new
world of possibilities for photo production of architecture, industry, art
objects, stills, fashion or beauty, all the way to portrait photography. With
LensTRUE you can unleash your creativity in a new way without either limiting
yourself to the central perspective or accepting perspective distortions.
