Lightroom 3 Noise Control & Lens Tool - part 1 of 1 2 3 4 5

Art Suwansang discusses the latest version of Adobe Photoshop Lightroom Lightroom 3 represents a great leap forward for photographers in the area of image processing. We can now enhance our digital images creatively in ways that couldn't be done before. There are a few new and refined tools that come to mind when we think of these improvement changes. Starting with the new Process Version (PV) 2010, which is an entirely new RAW demosaic algorithm, or RAW decoder, that works to enhance the images from the building blog of your digital image files, to the muchneeded refinement made to the noise-reduction algorithm, with the biggest advance made in the area of Luminance noise reduction. Also consider the new Lens Correction tool built right into the RAW adjustment fundamental. These are the tools that we'll spend time building up a familiarity with so that we can harness the great power of Lightroom 3 image-processing capabilities.

PV 201 Processing

Some might ask, why is PV 2010 such a big game changer? If we look at the history of Adobe Camera Raw (ACR) the last time that this RAW decoder or demosaic algorithm got an update was in 2003, which predates even the release of Lightroom 1 by about three years and is currently known as Process Version 2003 (PV2003). PV 2003 was a good RAW decoder and it still is; however, in the recent years digital camera sensors have gotten so much better especially in the area of high ISO. Suddenly, what was good in PV 2003 is no longer good enough to handle RAW images that were photographed with high ISO. For a while we were using a really old and antiquated algorithm to process our newer files, the result is a decoder that can no longer get the most out of our new digital files. Hence the release of the new PV 2010 algorithm that was designed with the current DSLR in mind. The result is a decoder that can now process new and older digital files more efficiently. PV 2010 is also deployed in Adobe Photoshop CS 5 as ACR version 6.


Now that we know some background about PV 2010, we should also know how and when it would affect us in Lightroom. At this point we need to separate our digital image files into two categories: first, brand new images that have not previously been processed with any former versions of Lightroom or ACR. While the second are images that have been previously processed in an older version of Lightroom and/or ACR. If your images fall within the first category then you can simply harness the new processing power with ease, when you bring them into Lightroom they are automatically processed using the new PV 2010 algorithm.
