Making Adjustments to an Updated Image
Because raw processing and noise reduction work so much differently in Process Version 2010, it’s a good idea to take a fresh look at an image’s noise reduction settings after updating the process version. For example, you may find that you can now suppress the same amount of noise using a lower noise reduction Amount, which also helps to preserve more detail.
Because raw images don’t receive that initial bit of noise reduction anymore, you may find that some images shot at high ISO speeds need somewhat more initial noise reduction and possibly less sharpening than they did in Process Version 2003.
In general, if you had developed a sense of where you like to position the noise reduction and detail sliders in older versions of Camera Raw and Lightroom, don’t leave yourself on autopilot after converting to Process Version 2010. Zoom into 100 percent, keep an eye on the subtle changes to detail and noise reduction, and be prepared to revise your typical noise reduction and sharpening values.
