X3F to PSD Converter

SIGMA X3F is the raw file format produced by Sigma cameras that use the Foveon X3 sensor. Unlike a conventional Bayer sensor, Foveon records red, green, and blue at every pixel location in three stacked layers, so an X3F stores three full colour measurements per pixel. This produces exceptionally sharp detail and colour accuracy, and it is also why X3F files are unusually large and demand Sigma-aware software.

How to open an X3F file?

The definitive application is Sigma’s SIGMA Photo Pro, which is the only program that fully understands the Foveon layer structure and delivers the intended colour.

Adobe Lightroom and RawTherapee can open many X3F files, though results vary by camera model, and XnView MP is handy for browsing. A common workflow is to develop the X3F in SIGMA Photo Pro, export a TIFF, and finish the edit elsewhere. You can also convert the file with our X3F to JPG tool.

Photoshop Document (PSD) is the default file type for Adobe Photoshop, a powerful and complex graphic design program. PSD can store an image along with a complex array of its corresponding layers, vector paths, objects, filters, and more, all in one file! PSD allows a user to make surgical edits on individual components of an image or a graphic design while retaining the file’s information in an accessible format. One drawback of PSD is that it can be large and unwieldy.

How to open a PSD file?

Adobe Photoshop is the most common program to open a PSD file. A free alternative to Adobe products is the GNU Image Manipulation Program, otherwise known as GIMP.

Due to the size of PSD files, they are not easy to transport, store, or share. To overcome this, PSD is often converted to a file format that can compress the data. Most often, the conversion is to JPEG, which offers lossy compression, or PNG, which offers lossless compression.
