I downloaded some EIP images and wanted to just play around their settings in Photoshop to practice. When I tried to open it, it says can't recognize the document format. The raw camera plugin is installed at the latest version. Why won't it open with Photoshop?
If you are referring to this EIP File Format – Enhanced Image Package, the format is specific to Capture One. Support by other programs is unlikely, and Adobe's list of supported file formats for Photoshop does not include it.
If you don't have the original files from which the EIP file was created, you may be able to use a standard unzipping tool to extract its contents. You may need to rename the EIP to ZIP before proceeding with extraction. See FileInfo: What is a EIP file?
