What is an Image?
An image is a visual representation of an object, idea, or scene. Unlike a photo, an image can be created through multiple methods, including:
- Drawings & Paintings – Created by hand using traditional tools (pencils, brushes, digital pens).
- Graphics & Digital Art – Designed using software for branding, advertising, or web use.
- Raster Images – Pixel-based formats like JPG, PNG, GIF commonly used in photography and web graphics.
- Vector Images – If you’re comparing visual formats, our guide on Raster vs Vector offers a detailed breakdown of how these two differ in structure and usage.
- Infographics & Data Visualizations – Graphs, charts, and diagrams that convey information visually.
- 3D Models & Renders – Images used in video games, animation, and architecture.
Key Insight: An image doesn’t have to be a photograph—it can be digitally created, drawn, or generated using software.
What are the types of images?
Images come in various forms, each serving a unique purpose across different fields such as design, photography, digital media, and visual arts. Below are the main types of images and their characteristics:
- Raster Images: Raster images are composed of a grid of pixels, where each pixel contains color information. These images are widely used in digital photography and web graphics. Common formats include GIF, JPEG and PNG. Raster images have a fixed resolution, meaning they can lose quality when scaled up.
- Vector Images: Vector images are created using mathematical formulas rather than pixels. They are composed of paths and control points, making them infinitely scalable without losing quality. These images are commonly used for logos, illustrations, and typography. Formats include SVG, AI, and EPS.
- 3D Images: 3D images are generated using specialized software to create three-dimensional representations. These images can be rotated and viewed from different angles. They are widely used in gaming, animation, product design, and architectural visualization.
- Infographics: Infographics combine data and visual elements to present information in an easy-to-understand format. Charts, graphs, and diagrams are common examples. These images are frequently used in marketing, journalism, and education to simplify complex information.
- Drawings and Paintings: Traditional images created by hand using pencils, paintbrushes, and other artistic tools fall into this category. Digital versions can also be created using software such as Adobe Photoshop or Procreate. This category ranges from simple sketches to detailed works of art.
- Digital Art: Digital art is created entirely using software and digital tools. It includes everything from simple illustrations to advanced animations. This form of imagery is widely used in graphic design, video games, and advertising.
What is a Photo?
A photo, or photograph, is a specific type of image that is captured using a camera. Unlike other types of images that can be manually drawn or digitally created, a photo is formed by recording light through a lens onto a sensor or film. This process makes photos a direct representation of reality. Photos that need to be used in large-scale designs often benefit from Image to Vector Conversion to preserve quality and scalability
What Are The Characteristics of a Photo?
- Captured by a Camera – Photos are taken using a traditional film camera or a digital camera.
- Realistic Representation – Unlike illustrations or digital graphics, photos depict actual scenes, objects, or people.
- Fixed Details – Photos capture specific moments in time, making them ideal for documentation and historical records.
- Used for Communication – Photography plays a key role in journalism, marketing, social media, and personal memories.
What Are The Types of Photos?
Traditional Photography
- Uses chemical film to develop physical prints.
- Requires darkroom processing.
- Common in historical and fine art photography.
Digital Photography
- Uses electronic sensors to capture and store images.
- Produces digital files that can be edited and shared instantly.
- Commonly used in smartphones, professional cameras, and social media content.
Black and White Photography
- Captures images in grayscale without color.
- Often used in artistic and documentary photography.
Portrait Photography

- Commonly used in professional headshots, family photos, and fashion photography.
Landscape Photography
- Captures outdoor scenes, including nature, cityscapes, and travel destinations.
- Requires careful composition and lighting techniques.
Macro Photography
- Focuses on extreme close-ups of small subjects, such as insects, flowers, or textures.
- Requires special lenses for capturing fine details.
Photos are an essential part of everyday life, providing visual documentation of real-world events, personal memories, and professional work. Unlike other types of images, photos preserve moments exactly as they happen, making them invaluable in storytelling and historical records.
How Are Photos Created?
Photos are created through a process that captures light from a scene and records it onto a photosensitive medium. This can be done using either traditional film photography or digital photography, each with its own methods and characteristics.
1. Traditional Photography
Traditional photography, also known as film photography, uses a chemical process to develop images. It involves:
- Light Exposure – A camera lens directs light onto a film coated with light-sensitive chemicals.
- Film Development – The exposed film undergoes chemical processing in a darkroom to reveal the captured image.
- Physical Print Production – The developed negative is printed onto photographic paper.
Traditional photography has a unique depth and tonal quality, making it popular in fine art, archival work, and analog photography enthusiasts. However, it requires specialized equipment and time-consuming development.
2. Digital Photography
Digital photography replaces film with an electronic sensor that captures and stores images as digital files. The process includes:
- Light Detection – The camera sensor converts light into electrical signals.
- Image Processing – The camera’s internal processor translates the data into a visible digital image.
- Storage & Editing – The photo is saved in formats like JPEG or RAW, allowing for easy editing and sharing.
Digital photography is widely used due to its instant preview capability, cost-effectiveness, and flexibility. It allows for real-time adjustments, high-resolution captures, and post-processing using software.
Traditional vs Digital Photography Comparison
| Feature | Traditional Photography | Digital Photography |
|---|---|---|
| Medium Used | Film | Electronic sensor |
| Development Process | Chemical processing required | Instant storage & digital processing |
| Image Quality | Rich tonal depth, grain texture | High resolution, sharp details |
| Cost | Requires film and development expenses | No ongoing costs after camera purchase |
| Editing Flexibility | Limited to darkroom techniques | Extensive editing options with software |
