About formats

X3F is the proprietary RAW image format used by Sigma cameras equipped with Foveon X3 direct image sensors, introduced in 2002 with the Sigma SD9 — the first digital SLR camera to use a sensor that captures full color information at every pixel location. Unlike conventional cameras that use a Bayer color filter array (where each pixel records only one color and the other two are interpolated), the Foveon X3 sensor stacks three photodiode layers at each pixel site, exploiting silicon's wavelength-dependent absorption depth to capture blue, green, and red light simultaneously. X3F files therefore store a fundamentally different kind of raw data: three complete color planes captured at the same spatial location, with no demosaicing required. The format uses a proprietary container with multiple data sections including the raw sensor data (compressed using a Huffman-based scheme), embedded JPEG previews, camera metadata, and Sigma-specific processing parameters. One advantage is the absence of demosaicing artifacts: because every pixel records all three colors natively, X3F images exhibit a per-pixel sharpness and color accuracy that Bayer-based sensors achieve only after interpolation — there is no moire, no false color, and no loss of spatial resolution from the color reconstruction step. This produces a rendering quality that many photographers describe as uniquely three-dimensional and film-like, particularly at low ISO settings. X3F files can be processed using Sigma's Photo Pro software, and are also supported by dcraw, Iridient Developer, and other RAW converters.

Initial release: 2002
MTV is a simple raster image format created by Mark T. VandeWettering for the MTV Ray Tracer, a ray tracing program released in 1988 as one of the early publicly available ray tracers distributed through Usenet. The format stores 24-bit RGB images with a minimal text header followed by raw pixel data. The header consists of a single line containing the image width and height as ASCII integers, followed immediately by the pixel data where each pixel occupies three bytes (red, green, blue) arranged in row-major order from top-left to bottom-right. The MTV Ray Tracer itself was significant in the history of computer graphics — distributed freely via the comp.graphics Usenet newsgroup, it introduced many programmers and students to the principles of ray tracing: ray-object intersection, reflection, refraction, shadows, and recursive shading. The MTV format was the program's native output, and its simplicity made it easy for users to write custom viewers and converters on whatever platform they had access to — a practical necessity in the fragmented Unix workstation landscape of the late 1980s. One advantage is extreme implementation simplicity: the format can be read in a handful of lines of code in any programming language, with no libraries, no compression algorithms, and no metadata parsing required — just read two integers and then read width x height x 3 bytes of pixel data. The format's historical significance in the computer graphics community provides another dimension — MTV files from early ray tracing experiments represent primary artifacts from the era when ray tracing transitioned from academic research to accessible software. MTV files are supported by ImageMagick and various legacy graphics tools.

Frequently Asked Questions

Why convert X3F to MTV?

The Foveon sensor captures unique three-layer color data stored in X3F — converting to MTV preserves this rendering in a universal format.

What opens MTV files?

MTV files can be opened with ImageMagick and MTV ray tracer rendering tools.

Is X3F to MTV conversion free on Convertio?

Standard conversions are available for free. Premium plans unlock higher capacity and priority processing for heavy use.

Are my X3F files safe during conversion?

Uploaded X3F files are deleted immediately after conversion. MTV outputs are automatically removed within 24 hours.

Can I convert multiple X3F files to MTV at once?

Yes — upload several X3F files simultaneously and each converts to MTV independently for individual download.
