PERSPECTIVE CONTROL

This assist function displays a frame showing the expected cropped
section of the image after a correction of the perspective of ver-
tical falling lines. Perspective Control helps to achieve a generally
straighter vertical line and straight horizon, which ensures a natural
image effect, specifically in architectural images.
The function "Perspective Control" calculates the image section
and the required distortion correction based on the actual panning
angles of the camera and the lens used. In effect, the camera ori-
entation during shooting (determined by internal camera sensors)
is the decisive factor and not the lines visible in the image object.
The function is therefore unlike automatic perspective control fea-
tures used for post-editing, which are generally based on the image
content.
The functionality depends on the image file format used (JPG or
DNG). For JPG format images, the correction occurs directly in the
camera and the corrected image is stored. For DNG format images,
the relevant information is written to the meta data of the original
image. Image correction is done later on using a program like Ado-
be Photoshop Lightroom or Adobe Photoshop

Notes
• In case of large panning angles, the distortion correction needed
for a complete perspective control would be too extreme. That is
why this function is automatically skipped or only partially used
where angles are too large. In that case, we recommend creating
DNG format images and effecting the desired corrections in a
post-editing step.
