What is a CR3 file?

The CR3 format is the third-generation raw image container developed by Canon Inc., introduced in 2018 with the EOS M50. It utilizes the ISO Base Media File Format (ISO/IEC 14496-12), replacing the TIFF-based structure of its predecessor, CR2. CR3 files store unprocessed sensor data and support C-RAW (Compact RAW) compression, which reduces file size by approximately 40% compared to standard RAW without significant degradation in dynamic range. The format encapsulates distinct metadata tags, EXIF data, and a full-resolution JPEG preview within a CIFF (Camera Image File Format) hierarchy.

How to open a CR3 file

Windows and macOS require the installation of the Canon RAW Codec or specific OS-level extensions (such as the Microsoft Raw Image Extension) to view CR3 thumbnails natively. For editing and full processing, Canon provides the Digital Photo Professional (DPP) software. Third-party post-production suites like Adobe Lightroom Classic (version 8.0+), Capture One, and DxO PhotoLab offer comprehensive support for CR3 demosaicing and color grading.

What is an EPS file?

The EPS (Encapsulated PostScript) format is a legacy vector graphics standard developed by Adobe in the late 1980s. It contains PostScript page description language commands describing 2D vector graphics, bitmap images, and text. Conforming to the Document Structuring Conventions (DSC), an EPS file includes a BoundingBox comment that defines the rectangular area of the graphic. It is strictly a single-page format intended to be embedded within other PostScript documents, often containing a low-resolution TIFF or WMF preview for onscreen display.

How to open an EPS file

While native OS support for EPS is deprecated in modern Windows and macOS (Preview no longer supports it as of macOS Monterey), professional vector editors are required for manipulation. Adobe Illustrator and CorelDRAW are the industry standards for editing EPS syntax. For viewing or rasterizing without expensive software, users can utilize Ghostscript, Inkscape (open source), or EPS Viewer. Converting to PDF is often recommended for broader accessibility.
