Alex - I assume you're rendering in "Accurate" mode, since you referred to setting the # of passes. Have you tried Fast mode? It's much faster and based on what I can see from your screenshot, it should be perfectly suitable. Faster results, with less noise, in the end... See Re: What is the exact difference between 'Fast Mode' and 'Accurate Mode'? for a bit more info.
Thanks for the reply. I thought I was forgotten
I dont remember changing that setting at all when I was doing both (perhaps I did). Its for packaging so its mostly a simple scene.
And I only have a Surface Pro 3 so it takes a long time to process in accurate. I saw on thyat post that the guy is doing 500 passes in 2 mins. It takes mine two hours on a simple white backdrop scene!
I need to learn next how to do lighting (since I know studio photography well) as the results I get on my render are hindered from the lighting.
