When you want the convenience of JPEG, the SD1 delivers print-ready images finished to Sigma's own high standards. For purposes of connectivity, photo sharing, social media, and other casual applications, you may find that JPEG meets your needs.
On the other hand, the compact file size of JPEG depends on irreversible "lossy" compression that leaves little room for post-processing creativity. When you want to explore the full artistic potential of the SD1, simply choose the RAW image format. This preserves 100% of captured information in all its 46-million-pixel glory, ready for you to give free rein to your creativity.
Sigma believes that shooting photos is just one stage of creating photographs. The creative process depends on carefully drawing out the latent power of the raw image to faithfully realize your vision in a work of photographic art.
Sigma's .x3f RAW image format files are your creative canvas. They let you work with the full dynamic range, broad color spectrum and delicate gradations of shadow and light that are gathered by the full color capture system. All the information recorded by the amazing X3 sensor is at your command.
Inspired by the virtually boundless potential of SD1 RAW format data, you embark on a voyage of artistic discovery with the exhilarating freedom to follow your creative muse in any direction.
In SIGMA Photo Pro 5.0 you will find precisely the functions you really need — no more, no less — to finish your photos with professionalism and artistry. With its intuitive and uncluttered interface, this digital darkroom application is unexcelled in RAW data processing performance. Even if you are new to RAW file formats, you will find it easy to use.
The redesigned interface offers greater functionality and convenience to give full expression to your creative ideas and bring out the awesome potential of 46MP images generated by the SD1's X3 technology. It also handles SD1 color mode setting data which optimizes color tone, contrast and other adjustments for various shooting conditions. These settings can be saved in RAW data files.
For image correction, the Adjustment Controls Palette offers seven parameters: exposure, contrast, shadows, highlights, color saturation, sharpness, and the X3 Fill Light feature. Together with the two noise reduction parameters and a color wheel, these controls give you the artistic latitude and precision to create the masterpieces that express your artistic vision.
