      Ok, so you're not after panoramas, but "normal" images.

      Btw. the CHDK can map the focus control to the zoom lever. quite useful.

      The PTLens database does not contain information for TCA correction, it only
      contains lens distortion correction settings. As far as I know the A630
      uses the same lens as the A610 and A620, so you can probably just copy the
      A620 entry in the PTLens database.

      The TCA correction parameters need to be specified on the command line given
      to fulla.

      I'm currently (slowly) working towards an improved lens database, but I'm
      not sure when this might be finished/available.
