Tips for 3D Renders
- Shoot architecture in soft morning or late afternoon light — harsh midday sun creates unflattering shadows
- Use a tripod for interior architecture photography — it ensures straight verticals and sharp images
- Correct lens distortion and vertical perspective in post-processing
- Include a scale reference (a person or known object) in photos where the scale of the building is important
- Deliver portfolio images at full resolution — clients will zoom in on material textures and construction details
