2. Texturing: Next, textures are added to the surfaces of objects to make them look like real materials, using mathematical algorithms within the software.

3. Lighting: Virtual lights are strategically placed in the scene to create the desired lighting effects, such as reflections and shadows, to make the scene look realistic.

4. Rendering: The final image is generated by specialized software, which calculates the color and position of each pixel based on the 3D model, textures, and lighting.

5. Post-processing: Finally, the rendered image can be further enhanced using software like Photoshop, where adjustments like color correction and filtering can be applied to improve the final result.

How to create photorealistic 3D visualizations: Best practices and tips

• Bevel application: Adding bevels to 3D renders makes objects look more natural by avoiding sharp edges.
• Photometric lighting: Using photometric lighting, especially with IES light profiles, mimics natural lighting more realistically.
• Blurred background effects: Adding depth of field blurs the background, bringing objects to the foreground for a more realistic feel.
• Chromatic aberration: Introducing subtle color fringing along high-contrast edges enhances realism without overdoing it.
• Specular maps: Specular maps highlight areas needing glossiness, adding realism to 3D models.
• Textures: Incorporating fine textures like wood or metal enhances the realism and helps convey meaning.
• Natural effects: Including natural elements like cracks adds authenticity and a human touch to renders.
• Asymmetry: Embracing asymmetry adds natural appeal, as real-life objects rarely exhibit perfect symmetry.
• Final renders: Making final adjustments like managing contrasts and colors enhances realism before completion.
• Rectifying common mistakes: Addressing errors in light placement, proportions, textures, and image management improves the overall natural look of renders.

Tips on how to distinguish render from a photo

1. Objects that are not the right size compared to each other. For example, if the chairs in a 3D living room look too small next to the coffee table, it’s a giveaway that the image is Computer Generated Imagery, also known as CGI.
2. Objects with too few details, make them look rough or jagged. This happens when the 3D models used don’t have enough polygons. Realistic renders need high-detail models with lots of polygons to look smooth.
3. When textures don’t match the shape of objects or look low-quality; In a good render, textures should look like they’re wrapping around objects correctly, like fabric on a sofa cushion or wood on a floor. Low-quality textures give away that it’s not a real photo.
4. Objects with sharp corners that look too perfect; Real things usually have softer edges, so objects in a CGI image with sharp corners stand out.
5. Images with distorted shapes because the camera settings are wrong. If things look stretched or squashed, it’s a sign that the rendering isn’t done well.
6. Shadows and highlights that don’t match the lighting or materials of objects; If the shadows are in the wrong place or the highlights are too bright, it’s easy to tell the image isn’t real.
7. Things look too perfect like chairs all spaced the same or cushions with identical folds. Real life isn’t that perfect, so when everything looks too uniform, it’s a giveaway that it’s not a real photo.
