What is RAW Image Format
When you take a photo using a camera or smartphone, the image is saved in a specific file format. Most people are familiar with JPG and PNG formats, but professional photographers often use RAW image format.
RAW images are very high-quality images because they store all the data captured by the camera sensor. Unlike JPG, RAW images are not compressed heavily and do not lose image quality. However, RAW files are very large and require editing before use.
In this guide, you will learn what RAW image format is, why it is important, when to use it, and how to use RAW images step-by-step.
What is RAW Image Format
RAW is an unprocessed image format that stores all the original image data captured by a camera sensor. It is called RAW because the image is not processed or compressed much.
RAW files contain more details, more colors, and more dynamic range compared to JPG and PNG. This allows photographers to edit images without losing quality.
Different camera brands have different RAW formats:
- Canon – CR2, CR3
- Nikon – NEF
- Sony – ARW
- Adobe – DNG
