Polaroid Photos — Convert, Resize & Organize
Information about the format: X3F
| Format | X3F |
| Company | Sigma |
| Description | An X3F file is a RAW photo from a Sigma camera with a Foveon sensor, which records red, green and blue at every pixel. Contenta Converter converts the full-size JPEG the camera stores inside the X3F file to JPG, PNG or TIFF, a whole folder at once. It does not develop the Foveon sensor data itself. Files from the Sigma SD9 and SD10 contain no such JPEG, so it cannot convert them. |
| Benefits | Nothing is baked in. You keep the full dynamic range (usually 12–14 stops), accurate colors, and the ability to change white balance, exposure, or color profile in post without losing quality. Shoot once, produce multiple interpretations later. |
| Drawbacks | File sizes are 20–40 MB for a 24 MP sensor, versus 5–8 MB for a high-quality JPEG. No web browser, email client, or phone gallery opens them directly — you need a RAW processor to view them. Every camera brand uses its own flavor, and older RAW files sometimes stop being supported as editors move on. |
