How to register the Lightroom Plug-In?
The Lightroom Plug-In talks directly with Hydra. That’s why you have to register Hydra’s Stand-Alone Version. • Open Hydra. • In the menu, choose Hydra, then Register / Buy a License… • Type your email address. • Copy the activation code you received by email, and paste it in the “License Key or Activation Code” field. • Click Activate. The Lightroom Plug-In is now registered through Hydra. You can therefore render HDR images without watermark within Lightroom.
