Note: PhotoLux HDRi images can only be created with the model in a perspective view.
Use the Render tab to set up a perspective view:
Adjust the Eye Distance setting to apply more or less perspective – wide angle or zoom lens
When you manipulate the view with MMB or Shift+MMB notice the eye icon in the centre of the screen, this is your view point – the position of your eye. Consider the eye position relative to the theoretical bounding box for your model.
This view can be saved in the saved views list – View tab> Named Views > Reorient > Saved Views
