It did let me shoot very near to the subject, but there's a lot of
barrel distortion, resembling a fish-eye lens.
This is also known as
barrel distortion and, for obvious reasons, is a characteristic that many portrait and lifestyle photographers try to avoid.
In this paper the radial distortion with its type will be addressed, the
barrel distortion which appears in lenses of short focal lengths and the pincushion distortion in lenses of longer focal lengths, as the other types normally have less significant impacts than the radial [7-9].
For the images acquired with the zoom lens, I corrected for
barrel distortion using a third-party plug-in.
Electronic Image Stabilization (EIS) and
Barrel Distortion Correction (BDC).
Furthermore, the exchange of information between the i-CS lens and the camera, enables easier formatting of Electronic Image Stabilization (EIS) and
Barrel Distortion Correction (BDC), which reduces the time needed for setup.
There was some minor
barrel distortion in the vertical plane on 1x but this went away as the magnification was increased.
Theia Technologies Linear Optical Technology enables an ultra-wide field of view without
barrel distortion through all-optical distortion correction, and without using software.
The most common distortion caused by the lens, is, in this case
barrel distortion that results from fitting the image in a smaller space.
I like how this corrects
barrel distortion for the lenses I use, so I actually bake it in as an Import preset, such that it is applied as I import my images.
Deformation of 2D barcode image includes
barrel distortion caused by the image acquisition device itself.
