Whilst making the first Wildcat catalogue we decided to try and make some of the jewellery in 3d. This was helpful for two reasons; sometimes we didn't have all the sample jewellery we needed and sometimes the sample jewelery wasn't high enough quality to take really good photos of.
It took a lot of experimentation to get photo realistic jewellery. To do so, I made a 3d model of our photography rig, fiddled with the lights and texture of the walls. Then I experimented with different rendering techniques.
