  • New feature: Accurate dual histogram display (LDR/HDR). The HDR histogram represents the merged, 32-bit image before tone mapping in a logarithmic scale (EV). The LDR histogram represents the currently displayed preview, it is a regular 8-bit histogram with a 0-255 scale. Histograms are computed in a separate thread to keep overall interactivity.

  • Improved: Incremental rendering as tiles is implemented.
  • Improved: Changing GPU setting in the preferences does not require Hydra relaunch anymore.
  • Improved: Faster window resizing.
  • Improved: Cancel rendering is now immediate when not using GPU acceleration.
  • Improved: The sharpen filter is now scale invariant, meaning that the preview rendering accurately demonstrates the effect as it appears in the full resolution output.
  • Improved: Automatic update is now signed for improved security.
  • Improved: Import progress sheet for images is displayed.

  • Aperture Plug-In: Shift key can be used to import modified versions of images into Hydra. This way, any modification in color temperature, contrast, etc. is made available to Hydra Plug-in. This remains an optional behavior as it has an impact on rendered image, and it can make the initial import process longer.
  • Aperture Plug-In: Auto updating of the Plug-in when a new version is posted.
  • Fixed bug: Importing images of different pixel sizes does not cause a crash anymore.
  • Fixed bug: Removing/adding images now resets reference points.
