What is it?
RAW is not a single format but a category of image formats that store unprocessed sensor data directly from a digital camera. RAW files contain all the data captured by the camera sensor before any in-camera processing.
Unlike JPEG which applies sharpening, noise reduction, and color processing automatically, RAW preserves every bit of sensor information giving photographers full control in post-processing.
Technical Specifications
Pros & Cons
Advantages
Preserves all sensor data for the highest possible image quality in post-processing.
Recover 3-5 stops of over/underexposed detail that JPEG permanently discards.
Edit RAW files without permanently altering the original data.
Access the full color gamut captured by your camera sensor.
Disadvantages
RAW files are 3-10x larger than JPEG files, requiring more storage and faster memory cards.
RAW files must be processed in software like Lightroom or Capture One before sharing.
RAW formats vary by camera manufacturer - a Canon CR3 requires different software than a Nikon NEF.
RAW workflows are significantly slower than JPEG due to file size and required processing.
When to Use It
Here are the most common situations where RAW Image is the right choice:
Профессиональная фотография
Use RAW for any photography where post-processing quality matters - portraits, landscapes, commercial work.
Студийная фотография
RAW is standard in commercial and studio photography for maximum control over final output.

How to open a RAW file
RAW file handling software can be categorized into professional-grade applications, free and open-source tools, browser-based solutions, and built-in operating system utilities. Professional software like Adobe Lightroom and Capture One caters to photographers who require advanced editing capabilities and extensive format support. Free and open-source options like Darktable appeal to budget-conscious users, while browser-based tools provide quick access for casual users. Built-in utilities often offer basic viewing and minimal editing features suitable for quick adjustments.
When selecting software for RAW files, important factors include feature fidelity, the balance between editing and viewing capabilities, cost models, platform compatibility, and export needs. Professional tools typically offer superior editing features and support a wider range of RAW formats, while free options may lack advanced functionalities. Users should also consider whether they need to convert RAW files for compatibility with other software or if they can work directly with the RAW format for their specific needs.
