After hitting Render this is what I was getting, in fact it was a lot more over exposed. Also I turned off Real-World Scale in the UV Maps on the Chair. The problem was with the exposure, aperture and camera distance. Once I had adjusted these three I got the render below which took 21 minutes.I found Nox Renderer nice and simple to use and I am looking forward to working with it more in future and seeing it develop.
NOTE. After writing this post Evermotion have posted some tutorials here. Check them out, there are some great features and you will probably get on better than I did.
