DxO Labs has released DxO Optics Pro v5.3, which the company describes as a major new release of its award-winning automatic image quality enhancement solution for digital SLR and compact camera users..

Most of the recently released digital SLRs feature impressive high ISO settings, sometimes as high as ISO 25600. DxO Labs notes that often these high sensitivities were of little practical use to photographers due to the very poor resulting image quality. The company says that its new RAW conversion technology breaks this limitation by delivering outstanding results in noise removal, detail rendition and colour fidelity at any sensitivity.

Using noise removal technology photographers can capture two stops more than usual, and may choose to take advantage of this gain to freeze movement, increase depth-of-field or capture images in even lower lighting conditions. Alternatively they may choose to invest money in less expensive lenses with smaller apertures, relying on DxO Optics Pro to compensate for the lower exposure.

DxO Optics Pro 5.3 adds RAW support for the recently released Nikon D700 and Canon EOS 1000D (called the Digital Rebel XS in the US), and noticeably for the high-end compact Canon PowerShot G9. Other recently announced DSLRs, including Canon EOS 50D and Nikon D90, will be supported by the end of the year. DxO Optics Pro v5.3 also supports cRaw format for Sony users.

The software is now compatible with Microsoft Windows 64-bit and Photoshop Lightroom 2. It also improves stability and numerous aspects of the user experience, including automatic download of available DxO Optics Correction Modules, automatic focusing distance recognition for Canon 40D, 1D Mark III and 1Ds Mark III, backup and restore of project database, more predefined presets, and better colour rendering options including a new 'neutral' colour rendering.

DxO Optics Pro 5.3 is a freely-downloadable update for owners of version 5. The full software costs €124 (£97) for the standard version and €249 (£194) for the Elite version, which adds support for higher-end SLRs such as Canon's EOS 5D and Nikon's D3.
