One of the most important feature for photorealistical renderings is 'imperfection'. this means, humans are thinking always in dimension which are defined by things surounding them. we see photos, videos and magazines each day and so we have a feeling for what is real and what not. if you look and renderings on galleries or advertising you'll often see that this isn't real. i wrote about some things like noise in another tutorial (compositing) and so we will discuss another technique now.
even if the problem with sharpness (or unsharpness) is based on imperfection of the technology for shooting pictures, it is a main part of product visualization and advertising. if you want to give the final touch to your product renderings you have to take 'depth of field' into a serious consideration. since lightwave comes with a 'not bad' depth of field effect but most of the people using it doesn't have any technical background of classical photograph the parameters for this effect are kinda strange to understand. this tutorial will cover how to set up a handy scene to manage the 'depth of field' effect with lightwave.
