This picture is a visualisation of a siemens vacuum cleaner.
The most difficult part was the lighting and the shading. Especialy the material of the cover was tricky. (it´s an multilayered, anisotrophic shader with a falloffmap in the diffusemapslot)The material have got a 3d effect in it (white points are in different dephts in the paint)
To watch this tiny details:
zoomable highres version
The lighting was done with 3 photometric area lamps an one spotlight.
The aim was to get perfect photorealism.
The final size of this picture was 4000 * 5000 px
Hope you like it.
