1. Understanding Image Rendering
In photography, image rendering refers to the process where a device or software translates image data into a viewable format. Basically, image rendering is the interpretation and transformation of data into an image we can see. This process occurs in multiple stages, from the moment you capture a photo to the final editing touches.
1.1. Image Rendering In-Camera
When you take a photo, the camera interprets data from the image sensor and converts it into a picture. The image displayed on the electronic viewfinder or LCD screen is the camera’s rendering of the scene. According to research from the Santa Fe University of Art and Design’s Photography Department, cameras use specific algorithms to render images, affecting the final look based on your chosen settings. Each camera model renders images uniquely, influenced by its internal processing capabilities.
1.2. Image Rendering During Post-Processing

During the editing phase, post-processing software interprets the data in each image file and renders it on your screen. Just like cameras, each image editing program has its own unique algorithm and output. How a software does photo rendering differs from one to another. The differences are particularly noticeable when shooting in RAW format, as these files contain more data than JPEGs.
1.3. RAW vs. JPEG: Understanding the Difference
One common misconception is that images “straight out of camera” (SOOC) are pure because they’re “unedited.” This is far from the truth. When shooting in JPEG, the camera applies its own edits based on your settings, including auto mode adjustments. Whether you choose to post-process the image or not, it has already been initially processed by the camera.
Shooting in RAW format, on the other hand, involves the camera collecting all the data into a large image file. The rendering of RAW images depends heavily on the software you use for post-processing. Unlike JPEGs, RAW photos allow you to make all the decisions about how the image will look, with the starting point determined by the rendering quality of your chosen software.
1.4. Image Rendering When Making Composites
In post-processing, rendering also refers to creating separate layers when making a composite image. It can also refer to the final image, when all the different layers have been merged into a flattened image and saved as a single file. This is sometimes called the “final render,” a term more commonly used in 3D image rendering.
2. Diving into 3D Image Rendering
3D image rendering is the most exciting and often referred to form of image rendering. Designers create separate elements (render passes) and combine them into a complete, lifelike image. When done well, these generated images are nearly indistinguishable from real photographs.
2.1. The Ubiquity of 3D Rendering
These days, 3D image rendering is ubiquitous, inundating everything from movies and gaming to online catalogs, architectural designs, and indoor decorating. As a photographer, you might not need to learn this type of rendering unless you provide product photography and want to offer clients more options.
2.2. The Future of Product Photography
3D rendering is changing how we create and display images online and may be the wave of the future. Technology is so advanced that it’s becoming more difficult to determine if a rendering is a photo or a generated rendering.
3. How to Improve Photo Rendering Quality
3.1. What Factors Influence Photo Rendering Quality?
The quality of photo rendering depends on several factors, including the camera’s image processor, lens quality, and settings, as well as the software used for post-processing. Better equipment and software generally produce higher-quality renders.
