Photo realistic rendering is a process of producing 3D images that are similar to photographs. It is widely used in architecture, product design, and visual effects where life like quality plays a crucial role.
The Important Part About 3D Rendering as Photo Realistic
Physically Based Rendering (PBR)
PBR materials are meant to reproduce the physical properties of real-world objects, reflecting light in a way that can be truly faithful to nature. PBR methods should be used to produce any materials except for metal, glass and fabrics.
Set Up Realistic Lighting
One of the most important things about photo realism is lighting. Set up realistic lighting conditions with HDRI environments, or use a three-point lighting setup to create perfect studio-style renders.
Use High-Resolution Textures
Photo realism demands a high-fidelity in textures that mimic fine surface details. Textures must be high resolution so they do not look blurry or pixelated on closeups.
Optimize Camera Settings
Leverages realistic camera settings like Depth of Field (DoF) and Motion Blur to reproduce real-world cameras. This adds realism to the scenes by simulating how a camera lens captures the world.
Post-Processing
Post Processing: After rendering, you will still edit in post processing software like Photoshop or Blender Compositor to get the desired color balance, contrast and sharpness. Drawing a balance at adding subjects like bloom or vignettes can give the image a more realistic look.
How to Get Photo Realism
Small Details: Whether dealing with scratches finger prints, dust etc — make an effort to show such minor details.
Natural Imperfections: Real world objects are not perfect. Give the materials a tiny bit of imperfection, be it dents or wear to make your scene look more realistic.
These are the things you need to focus on creating breathtaking glowing renders that are indistinguishable from real-life photograph.
