The Lens Correction tool provides controls to correct for several types of optical distortion inherent in most lenses. For more information about lens correction effects, see the Understanding Advanced Image Editing Tools topic. To set the lens correction options:
There are three types of corrections that are available; each can be used alone, or with the other Lens Correction tools:
Note: Chromatic Aberration is most noticeable in high-contrast areas towards the corners of an image. Position Zoom Window on a corner of your image while adjusting the R / C and B / Y sliders to fine-tune the CA correction.
Up through Bibble 4.7, lens distortion correction in Bibble - provided in the BPTLens plug-in - was compatible with Tom Neimans' PTLens text database. Tom has recently changed to using a private binary format for his database and changed his licensing terms and thus our database is currently not compatible with his latest database. Beginning with Bibble 4.8, lens distortion correction has been reworked and moved inside the main Bibble application. Besides providing a more integrated solution, we've also added additional controls to correct Chromatic Aberration and light falloff due to lens vignetting. All of the lens profiles available with the last (4.7) version of the BPTLens plugin are also included and supported in Bibble 4.8. Bibble Labs will provide our own new calibrations as lenses and cameras are introduced. If you have a lens or camera that isn't currently supported and would like to ask us to include it, please visit our Lens Calibration page for information on how to send us the necessary test shots. In addition to the new controls you will also find that the lens corrections are applied faster and don't require as much memory as before. |
