The IFMA project is one of the biggest project I worked on. "Societatea Română de Ascensoare IFMA S.A." (a Romanian company which creates elevators) needed a presentation catalog for their elevators. Beginning from June 2003 to September 2003, I worked for 6 high quality, photo-realistic, elevators ready for printing. I also made 36 variations at a lower quality for a CD presentation application which allows the IFMA clients to customize their own elevator by picking the materials and the models they want for ceilings, floors, walls, control panels and other details. For the catalog I made multiple renders with close-ups of the displays, ceilings, floors, control panels and other parts. In July 2004, I was contacted to make over 20 new high-quality renders of newer elevator models.
Probably you are asking "why make a catalog with elevators generated on a computer?" Photographers have a hard time making good quality photos in such high-reflexive elevators. The resulted photos can hardly be used in a catalog.
Attention: I do not create real elevators :).
