Noise Reduction: Lightroom 3 vs. Lightroom 2.5

lr2.5 vs lr3 500x375 Noise Reduction: Lightroom 3 vs. Lightroom 2.5

In the last few months or so, the “megapixel war” has shifted from megapixels to high ISO sensitivities. High ISOs are the new megapixel.

Which is good. Because it is far better to have less noise at higher ISOs than cramming more and more megapixels into the sensor… which only results in more noise being added to the mix.

Already there are some cameras that produce truly amazing “silky smooth noiseless” high ISO images. For example, a Canon 5Dmk2 produces far better images at ISO 4000 than a Canon 300D did at ISO 800; probably even better than at ISO 400.

Now enter Lightroom 3. Version 3 of Lightroom offers what is probably the best noise reduction improvement in years. Take the above screenshot (link goes to full size screenshot, 2.88MB), which shows an image taken at a concert at ISO 4000. The left split shows Lightroom 2.5´s engine and the right split shows the new engine from Lightroom 3. Even at this smaller size you can see the differences between the two. If you download the full size screenshot, you can compare the two splits in more detail and see that the newer engine produces a smoother, finer image.

And this is merely “updating” the image to use the new engine; no actual noise reduction was applied and no parameters were changed.

The next image shows the almost the same crop, but a bit to the right to show the hair. It has a single noise reduction parameter changed, Luminance from 0 (default) to 23 (again, link goes to full size screenshot, 2.77MB).

This is again a big improvement but the image starts to lose just a smidge of detail/sharpness as can be seen in the hair area and the eyebrows. Of course, given the end result, it´s entirely acceptable, all the more so taking into account that there are still plenty of parameters to tweak and get that detail back.
