Sigma Press Release 27/08/04

The Sigma Corporation is pleased to announce the launch of Sigma Photo Pro version 2.1. This major update delivers exciting levels of performance to the Sigma Photo Pro program, specially designed for the SD9 and SD10 digital cameras.

Benefits and features of the new update:
- White balance override available as an option in the software, allowing users to change / correct white balance settings after the photograph has been taken.
- Monochrome as a white balance option, allowing users to add a colour tone to monochrome images via the colour adjustment tool.
- Original white balance setting, allowing users to revert back to the default white balance.
- Additional information shown on the Info bar including; lens focal length range, eg. ‘28mm (15-30)’, white balance setting and metering mode.

Sigma continually strives to improve the features of previous versions of the Photo Pro software. Version 2.1 has an improved Auto White Balance calculation, especially effective for long exposures. In addition to this, problems with highlight colour and purple fringing have been fixed,

This new version of Sigma Photo Pro is now available for download free of charge, for new and existing customers, from Sigma Imaging (UK) Ltd?s website www.sigma-imaging-uk.com.

Sigma Photo Pro 2.1 software is used for modifying recorded RAW data image files. It is easy to make adjustments (white balance, exposure, color balance, and contrast for example) in three modes. The X3F mode stores the original settings of the image at point of capture. In the auto adjustment mode the software analyzes and automatically makes adjustments of RAW data. The custom-mode allows the photographer to make individual adjustments to exposure, contrast, shadow, highlight, sharpness, and saturation.

SIGMA Photo Pro supports 8-bit TIFF, 16-bit TIFF, and JPEG file formats and also outputs images in four-color space (s.a. sRGB and AppleRGB). The default setting for resolution is the same as the resolution selected when capturing the image on the camera (High, Medium, or Low). It is also possible to select one half, or double the resolution for the processed image, allowing for full 16 bit, 80 MB images from the original Raw file. This is of course only possible due to the 10.2 mega pixel sensor recording all three primary colours at individual levels.
