All About Photorealistic Renderings

Jan 25, 2023 | 3d Renders

Photorealistic renderings are at the forefront of digital or computer-generated art. Anyone who deals with detailed and rich imagery — advertising agencies, real estate brokers, motion picture studios, and the like — is using or looking to use photorealistic renderings.

Unlike other images, photorealistic renderings provide unparalleled graphic depictions of reality. If you’re looking to leverage photorealistic images in your company, we’ll help you understand their basics, including what they are, who uses them, what makes them so realistic, and more.

Let’s begin with what photo rendering is.

Understanding Photo Rendering 

Rendering, also known as image synthesis, is the process of translating image data into a viewable photorealistic or non-photorealistic image. A render is created with the help of a computer program that gives objects their final appearance.

Rendering allows the user to create a computer image that can be viewed and manipulated for different purposes.

What Is Photorealistic Rendering?

Photorealistic rendering, or photorealistic visualization, is a form of 3D rendering that generates life-like images and animations using a rendering engine. It is a type of art that is brought to life by virtual lights, shadows, camera angles, and materials that are similar to the physical world. This allows you to depict different objects as they might appear in real-life settings. 

It includes minute details such as how light falls on the object, textural differences between different sections of the subject, and how it interacts with other surfaces, elements, and environments. Plus, you can rotate and view it from various angles and lighting which can help you fine-tune your results and provide different dimensions to them. 

Once a photorealistic rendering is complete, you get a high-quality image that is nearly impossible to distinguish from a photograph.

Who Uses Photorealistic Renderings?

Photorealistic renderings are used in various processes and professions. Here are their common uses in major industries: 

Marketing

Photorealistic renderings are often seen on e-commerce sites, allowing users to see their desired product from different angles before they hit buy. 

Healthcare

It is used in the medical industry to teach healthcare professionals about organs, pathological procedures, medical concepts, microbiological objects, etc.

Real Estate and Architecture

It is integral to real estate and architectural projects. Engineers and construction crews from these industries rely on third-party 3D rendering firms to show clients what a project would look like. It also helps fast-track construction permits. 

Photorealistic renderings offer accurate dimensions and structures so it’s easier to identify and address potential design and construction issues. Real estate buyers can better appreciate properties if they have photorealistic versions of what they’re buying.

Entertainment

One of their most engaging and exciting applications is in video games and movies. Rendering technology has advanced to a point where we can recreate human expressions and features. Human rendering is one of the most challenging forms of photorealistic visualization but the results are eerily and impressively lifelike.

Types of Photorealistic Rendering

There are two types of photorealistic rendering: real-time and final-frame.

Real-Time Photorealistic Rendering

In real-time rendering, you can make complex renders instantly. To top it off, you can also explore and interact with the scene and make changes. The best thing is these changes can be reflected in the initial render almost immediately, speeding up production time. 

Real-time rendering is done with two key technologies: ray tracing — which creates an image by simulating the natural behavior of light, and rasterization — which converts vector graphics into a raster image

Final-Frame Photorealistic Rendering

With final-frame rendering, you can combine geometric shapes into a high-resolution image. It allows you to press pause on the rendering for a clear image at the highest setting when the object stops moving. This results in reduced pixelation and a render that’s very similar to the original image.  

What Makes a Render Photorealistic?

How do renderers give their images photorealistic qualities? What should you look for and how can renders be improved?

Here are some common elements and techniques to keep an eye on:

The Inclusion of Flaws and Imperfections

In reality, nothing is perfect. That’s why a render that’s too perfect feels unrealistic. Photorealistic renders should thus have small imperfections that can be found in real life. 

Examples of flaws that can add to a render’s realism include dirt, humidity, scratches, signs of aging, glare, and discoloration. For example, renderers can add dust or dirt to a carpet. They can also experiment with asymmetry.

Blurring

Have you ever taken a picture using portrait mode? If so, you may have noticed how specific areas of the image come into focus while others blur in the background. 

This can be replicated in renders with chromatic aberration. Chromatic aberration, or color fringing, is a great way to make renders more life-like. 

Additionally, renderers can also play around with the settings and incorporate depth of field, different compositions, and motion blur to make them more realistic. 

Different Lighting 

Observe the world around you. When you do, you’ll notice that objects in the real world aren’t illuminated from all sides evenly so photorealistic recreations should follow the same principle. 

Photometric lighting can help you achieve more a lifelike effect. It allows renderers to use the actual measurements of light from different angles, perspectives, and distances so that it can be applied to a render. These measurements are translated into an algorithm and processed by software.

Realistic lighting can be challenging. As a client, you may want your renderer to play around with different types of illumination, tones, temperatures, sharpness, shapes, color, brightness, etc. before settling on a final version. You’ll discover that lighting has a huge impact on the look and feel of the render. 

Texture Mapping 

High-quality and realistic textures are basically 2D images that add an insane level of detail and realism to 3D renders. 

Every material — such as wood, leather, and metal — behaves differently. It takes a certain skill for renderers to work them into their images with lifelike accuracy. The end result must be a seamless image. Small and intricate details must not detract from the overall effect but should enhance its realism. 

Well-rounded Edges With Bevels 

The real world is more defined than the digital world, but it’s not razor-sharp. Hence, 3D models with rigid geometric shapes and acute, sharp edges can look artificial.

That’s where bevelling helps. In graphic design, bevelling enhances the 3D qualities of an image by highlighting inner and outer spaces within it. When bevelling is used, the effect is more depth and dimension, giving objects a raised and more realistic appearance.

A bevel tool helps create chamfered, rounded, and smooth edges on objects. It also improves how light and reflections affect a particular subject.

Why Is Photorealistic Rendering Important?

Photorealistic rendering offers several benefits. We’ve listed 3 major advantages below. 

1. Helps You Visualize the Finished Project

Sketches and mood boards can set the tone for projects, but they’re not enough to appreciate their finer details. It’s much easier to get everyone on the same page and create buy-with photorealistic renders. 

Since they’re much more lifelike, they’re better for engaging stakeholders and setting manageable expectations with fewer unpleasant surprises.

2. It Minimizes the Risk of Errors 

Using photorealistic visualizations minimizes the risk of doubts and uncertainties by showing every little detail whether it’s a home, a video game character, or an ad display. 

If there are potential issues, they can be addressed early on and adjusted until you’re satisfied with the smallest tweaks. The same file can be re-edited so everything stays the same except for the changes you want.

As a client, you get to nip errors in the bud and can have them fixed quickly and efficiently. 

3. It Elevates Your Project

Photorealistic renderings look impressive regardless of your industry and need. They can make any presentation, project, or artwork more compelling because of their uncanny ability to replicate the real world and make it seem even better. 

It doesn’t matter if you’re a B2B or a B2C — if you want to impress your managers, clients, business partners, or colleagues, photorealistic renderings are the way to go.

Of course, you can only fully enjoy all these benefits if you have quality renders that are decidedly realistic. So, shop around for trusted providers, ask for their portfolios, and don’t be afraid to compare companies.
