In the past there was a +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 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 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").
