The goal of the lensfun library is to provide a open source database
|
||
|
|
of photographic lenses and their characteristics. In the past there
|
||
|
|
was a effort in this direction, 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 database
|
||
|
|
and search for specific things in it, but also provides a set of
|
||
|
|
algorithms for correcting images based on detailed knowledge of
|
||
|
|
lens properties. 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").
