Canon RAW (Legacy)
The ancestor of modern Canon raw formats.
CRW (Canon Read/Write) is the original raw image format used by early Canon digital cameras, such as the EOS D30, D60, 10D, and the original Digital Rebel (300D). It predates the CR2 format. Unlike modern raw formats that are typically TIFF-based, CRW uses the CIFF (Camera Image File Format) structure. It often comes paired with a .thm (thumbnail) file, which contains the preview image and metadata.
CRW files store raw sensor data, usually 10-bit or 12-bit. The file structure is quite different from CR2/CR3, organizing data into a heap of 'chunks'. Because it is a legacy format, it does not support modern features like GPS tags or advanced lens profiles natively, though software can apply them in post.
CRW was used from 1997 until 2004. It was replaced by CR2 because CRW had limitations in file size and metadata extensibility.
TIFF (Tagged Image File Format)
The venerable standard for print, scanning, and archival.
TIFF (Tagged Image File Format) is one of the oldest and most robust image formats still in use. Created in 1986 by Aldus (later acquired by Adobe), it was designed to be a universal standard for desktop publishing and scanning. TIFF is a container format, meaning it can hold almost any kind of image data—compressed or uncompressed, RGB or CMYK, 8-bit or 32-bit. This flexibility makes it the go-to choice for the printing industry, professional photographers, and archivists who need a format that preserves maximum quality and metadata without the compatibility headaches of proprietary RAW files.
A TIFF file is built around 'tags' that describe the image data. This allows it to support a vast array of features, including multiple pages (used for faxes and document scans), multiple layers (like a PSD file), and various color spaces like Lab and CMYK that are essential for printing. TIFF supports multiple compression schemes. The most common are LZW (lossless) and ZIP (lossless), but it can also hold JPEG (lossy) data. Uncompressed TIFFs are standard for archival because they are future-proof and require no decoding algorithm that might become obsolete.
TIFF was the first format to bring high-resolution, grayscale, and later color images to the desktop publishing revolution of the late 80s. While JPEG took over the web and consumer photography, TIFF remained the king of the pre-press and scanning world. It hasn't changed much since Revision 6.0 in 1992, which is a testament to its robust design.
