Photomatrix 5

This app is actively developed by an FX TD (Visual Effects Technical Director), aiming to allow fast and no-brainer preparing 360° images for producing HDRI images efficiently with Theta S or Theta SC. Images taken need to be exported to another app or on computer to merge them into the .hdr or the .exr file. There are lots of options to do that, it is suggested to use Photomatrix, PT Gui, Photoshop or Lightroom with plugin.
