Hi, thank you for your participation 
,
Yes, it is in this spirit … but we must put it into perspective (see below) !
Yes, that’s what I did, you can find everything, but a large majority is a presentation on a plain black, white or other background, sometimes degraded with often an image but clearly dissociated !
I grant you, for the second point, it’s only a “draft” to put into practice what sundialsvc4 said and for the first point, I reinforced the values to better see the chosen texture :
Initially, I excluded typographies and “photo” images, I only wanted a beautiful background that highlighted my 3D work. My choice was rocks or stones to recall the gems or the asphalt with the checkerboard to recall the circuit or the Daytona race.
See you …
