The goal of the lensfun library is to provide an open source database of
|
|
photographic lenses and their characteristics. In the past there was an
|
|
effort in this direction (see http://www.epaperpress.com/ptlens/), but then
|
|
author decided to take the commercial route and the database froze at the
|
|
last public stage. This database was used as the basement on which lensfun
|
|
database grew, thanks to PTLens author which gave his permission for this,
|
|
while the code was totally rewritten from scratch (and the database was
|
|
converted to a totally new, XML-based format).
|
|
|
|
The lensfun library not only provides a way to read the lens database and
|
|
search for specific things in it, but also offers a set of algorithms for
|
|
correcting images based on detailed knowledge of lens properties and
|
|
calibration data. Right now lensfun is designed to correct distortion,
|
|
transversal (also known as lateral) chromatic aberrations, vignetting, and
|
|
colour contribution of the lens (e.g. when sometimes people says one lens
|
|
gives "yellowish" images and another, say, "bluish").
