Photo close-ups of real things are often ugly and don't meet the requirements (dust, bumps, irregularities). Thus a 3D visual can be the best solution. Here's a threaded bolt with texture and micro scratches to serve a detailed but clean appearance. This object, since made from blank metal, reflects the background it is set against, therefore it was necessary to render two versions: One for a dark background and one for a bright one. Images were indended to be printed in a large format, so I rendered them in 12.000x6.2000 pixels with alpha channel for the customer's convenience.
