DxO Labs has released version 4.5 of its DxO Optics Pro photography suite for Windows and Macintosh systems. The upgrade includes a plug-in for Photoshop Lightroom, and direct output to Flickr.

DxO Optics Pro 4.5 features the first third-party plug-in for Photoshop Lightroom, according to DxO Labs, allowing photographers can now integrate DxO Optics Pro and Lightroom into their workflow.

Via the plug-in, users can send their images straight from Adobe Photoshop Lightroom to DxO Optics Pro for processing and save corrected files directly into their Lightroom library (with the image metadata intact). There's also a 'Export to Lightroom' feature within the stand-alone version of DxO Optics Pro v4.5 which enables users to send their images directly to an Adobe Photoshop Lightroom library.

DxO Optics Pro v4.5 includes the previously announced free Flickr Export plug-in allowing automatic login, tagging and fast uploading of DxO Optics Pro processed images to Flickr, Yahoo's popular photo-sharing Web site.

The new Automatic Crop function maximizes the remaining image surface, respects the height/width ratio and preserves the geometric centre of the image providing users with an immediate view of the final effect of the crop. DxO Labs says that this feature is particularly useful on a batch of images that have been corrected for horizon alignment or perspective, for example.

DxO Optics Pro v4.5 faster and more efficient, according to DxO Labs. RAM usage is more economical (with DxO claiming up to a 50 per cent gain) and, with the beginning of Graphic Processing Unit (GPU) implementation, there are significant display speed gains -- again of up to 50% depending on the user’s hardware.

The upgrade to DxO Optics Pro v4.5 is free for all users of DxO Optics Pro v4.x (4.0, 4.1, and 4.2). New purchases cost £41 for the Starter version, £84 for Starter, £169 for Elite (all exclusive of VAT).
