In an industrial setting, it is common for PCB/component inspection to take images using a telecentric lens, to eliminate all perspective on any tall components around the sides (and also allow precision measurement using optical processing only). That, coupled with good lighting and sometimes polarization can result in pictures of components so perfect that they look like they were renderings.
