Exposure - daylight vs artificial indoor lighting
It comes as a surprise to many Maxwell users not familiar with photography that their daylight camera settings produce a very dark rendering when using only common emitter values for indoor lighting and the same camera settings as the daylight render.
Small objects in focus
Close to human vision
In many cases you may wish to present a product, especially furniture in a way that resembles how we would see it in real life - no perspective distortions or out of focus areas. In these cases use a pretty high F-stop so the whole object is in focus (f8 - f16) and a focal length of about 35-50mm which is considered a "normal" focal length. The human eye focal length is smaller than that (around 17mm) giving us a wider FOV, but because we tend to focus our attention selectively on a certain area we don't really observe the world as if we had wide angle lenses attached to our eyes.
