What is a Sigma RAW (X3F) file?

Sigma RAW is the raw image format written by Sigma’s SD and dp cameras, saved with the .x3f extension. Its distinguishing feature is the Foveon X3 sensor behind it, which captures red, green, and blue at every pixel instead of interpolating colour from neighbouring photosites. The result is a raw file with remarkable per-pixel detail, though the trade-off is large file sizes and a narrower choice of compatible software.

How to open a Sigma RAW file?

Use Sigma’s own SIGMA Photo Pro. It is purpose-built for Foveon data and produces noticeably better colour and detail than generic raw converters.

Some third-party developers, including Adobe Lightroom, RawTherapee, and XnView MP, can open Sigma RAW files, but support depends on the camera model. Developing in SIGMA Photo Pro and exporting a 16-bit TIFF is the most reliable route into other editors. You can also convert the file with our X3F to JPG tool.

What is a BMP (Bitmap) file?

Bitmap (BMP) is a pixel-based file format that stores two-dimensional images, generally without any compression. BMP utilizes a dot matrix data structure called raster graphics, which establishes the color depth of the image. BMP is mostly used for digital publishing of photographs. However, due to the lack of compression, BMP files are usually large.

How to open a BMP file?

BMP can be device-dependent or independent. BMP opens readily in the Microsoft Paint application and is often associated with Microsoft operating systems. Despite the association with Microsoft, a device-independent BMP, or DIB, can open on almost any device, operating system, or application.

In addition to opening BMP files, many applications can be used to create them, such as Adobe Illustrator. Should you need to convert the BMP into a vector-based image, then consider using CorelDRAW. Other applications that can open BMP files include Adobe Photoshop, Microsoft Photos, Apple Preview, Apple Photos, and ColorStrokes.
