Canon introduced CR2 in 2004 with the EOS-1D Mark II, replacing its earlier CRW format, and kept it as the standard RAW format across the EOS line \u2014 DSLRs from the 20D through later Rebel and 1D-series bodies \u2014 for the better part of fourteen years. Being TIFF\/EP-based made CR2 relatively easy for third-party software to support from the start, since it followed a documented structural convention rather than an entirely bespoke container.<\/p>
In a DAM, CR2’s embedded JPEG preview is the workhorse feature: it lets a system generate a usable thumbnail instantly rather than waiting on a full raw-processing pass, which matters at the scale of a photo library with tens of thousands of RAW files. The metadata that actually matters for search and rights tracking \u2014 capture settings, lens, camera body \u2014 lives in Canon’s MakerNotes block, which most mainstream raw processors parse correctly given CR2’s age and ubiquity. The main archival consideration is generational: Canon’s current cameras all shoot CR3, so CR2 is now a legacy format from a support standpoint, even though it remains widely readable today.<\/p>","protected":false},"excerpt":{"rendered":"
