1.2.6

Additions

Bugs Fixed

Bugs Fixed

  • fixed bug where inf depth values would result in erroneous depth slice results

1.2.4

Additions

  • improved corrective slices for deep images

1.2.3

Additions

Bugs Fixed

  • resolved cache issues with deep images ( causing “can’t access deep row” errors )

1.2.1

Additions

Bugs Fixed

  • fixed update crash, this caused instability when adjusting parameters while Bokeh was still updating

  • refactored real world lens equations
  • removed lens style option in favour of a more correct default
  • we’ve removed the zeiss formula input and reverted back to the traditional ( 1730 ) value, most of our newly derived equations are based on this. If you need it back for some reason email support@peregrinlabs.com.

Bugs Fixed

1.1.2

Additions

  • rewrote kernel scaling routines ( defaults to true cubic )
