Noise Reduction Observation #1

One of the (valid) complaints about Aperture is that it’s noise reduction doesn’t do that good of a job.  However….in playing with the noise reduction under RAW Fine Tuning, I’ve found I can get the same results as in Lr.

I would be interested in you sharing your method/findings in detail (pretty please) … I’m likely not alone in that respect … I’ve always found the RAW fine Tuning adjustments to be a bit contrary and finicky …

I haven’t had the time or patience to delve further into the RAW Fine Tuning and would appreciate any insight you or others would care to share.

I too would love to see an ApertureExpert Tip (guest article) on this.

I’ll work something up with pretty pictures and submit it for approval, but here’s the quick and dirty -

I shoot with a Nikon D7100 and regularly shoot at ISO 3200 and 6400.  The image quality is very good at these ISO’s, and VERY sharp, but the lack of an optical low pass filter does introduce a bit more luminescence noise.

First, zoom into 100% to an area where you can see noise.  Then, go into RAW Fine Tuning, and adjust D-Noise to about 70-75% for an ISO 6400 shot, and then applying about 25% to the Detail slider, this reduces a large part of the noise while bringing back detail.  I don’t touch any of the other noise reduction sliders, mostly because they tend to cause more blurring than the D-Noise slider does.

Depending upon your camera, your adjustment to the D-Noise slider will vary, but I’m finding it to be very effective.

Wow! Wow!! 

Fantastic tip, just one question, what’s the ‘detail’ slider. Is that camera specific?

OK, found it. D5200 and D610 have Sharpening and Detail sliders, but my main camera D300s has Sharpening and Edges.

All of the sliders I used are under the RAW Fine Tuning brick.  Edge Sharpen and Sharpening are separate bricks in and of themselves (Edge Sharpen rocks!)

Yes, me too, but what those raw processing sliders are called depends - amazingly - on which camera you used!

Or the RAW engine version used by Aperture when the camera RAW support was added by Apple … I’m not sure legacy RAW conversion has been totally updated when there were changes made over time …
