Other than seeing the rendered image you can also make adjustments to your image on the right.

Feel free to delete this light when done. To demonstrate this we can add a light to our scene by clicking on Create Corona Light and clicking and dragging in our scene. Any changes we make in the viewport are reflected in the render straight away. We can now see our preview render in real time. You can read about installation and activation on our helpdesk if you need any assistance.
