About .spi3d Files
SPI3D files are plain text files used to store 3D LUT (lookup table) data for color grading in digital imaging workflows.
They follow the text/plain MIME type, making them human-readable and easy to edit with basic text editors.
- Main Use Case: Managing precise color adjustments for films, animations, and other visual media.
- They store numerical values that map colors from one space to another.
- They are often integrated into image and video processing pipelines to maintain color consistency.
- Viewing/Editing: Use simple text editors like Notepad or TextEdit for direct editing.
- Specialized software for color grading and visual effects may import these files.
They combine technical efficiency with the simplicity of a plain text format, supporting both manual tweaks and automated processing.
Relationship between file extension and MIME type
A file extension is a suffix at the end of a filename that indicates what type of file it is. File extensions help both users and operating systems identify what application should be used to open the file.
File extensions are typically separated from the filename by a period (dot) and consist of 2-4 characters, though they can be longer. For example, in the filename "document.pdf", ".pdf" is the file extension.
File extensions are closely related to MIME types, as they both serve to identify the format of a file. However, while MIME types are used primarily by web browsers and servers, file extensions are used by operating systems and applications.

FAQ
What is a MIME type?
A MIME (Multipurpose Internet Mail Extensions) type is a standard that indicates the nature and format of a document, file, or assortment of bytes. MIME types are defined and standardized in IETF's RFC 6838.
MIME types are important because they help browsers and servers understand how to process a file. When a browser receives a file from a server, it uses the MIME type to determine how to display or handle the content, whether it's an image to display, a PDF to open in a viewer, or a video to play.
MIME types consist of a type and a subtype, separated by a slash (e.g., text/html, image/jpeg, application/pdf). Some MIME types also include optional parameters.
How do I find the MIME type for a file?
You can check the file extension or use a file identification tool such as file --mime-type on the command line. Many programming languages also provide libraries to detect MIME types.
Why can one extension have multiple MIME types?
Different programs and historical usage may assign various MIME identifiers to the same file format. Listing them together helps maintain compatibility across tools.
