3D photography generally takes longer than still photography. For homes, plan on 45 minutes per 1,000 square feet, plus 15 minutes for set up and planning. A 3,000 square foot home will take approximately 2.5-3 hours to complete.
In commercial/office environments the photography generally takes less time, but is dependent on type of space and level of detail required. As an example, an art gallery would take longer than a space the same size with open offices.
