Adjustment Brush Secret
« on: April 01, 2010, 02:34:59 AM »

Hi Folks:  The 2nd "Lightroom Brownbag" get together was today, and Tom Hogarty was giving an overview of some of the Lightroom 3 Beta 2 improvements.  One bit of information he gave out that, according to him hasn't been written anywhere yet, is that in the Adjustment Brush, setting sharpening at -50 to -100 now introduces a form of lens blur.  It was a 'thank you for coming' tidbit.  Haven't tried it yet, but I'm sure it will have its place.

It was mentioned but not specified over on the LightroomNews site..

This doesn't seem to have 'much' affect, certainly its more like a brush on noise removal than a lens blur.  Moving the clarity to match (skin softening technique) actually has more of a blurring effect.

This is -100 on the sharpening slider with a brush ... with the original having only default sharpening applied.

Yes, this is my point.  Its maxed at -100 and the effect is barely noticeable when viewing a full size image.  Doing the same with the clarity actually adds more of a "blurring" effect.  I don't see this as much of a feature at all.

Have you tried adding multiple brush adjustments? The results are accumulative you know...

Yes, but by the time I do that I can import the file into CS4 and brush as much "blur" as I wish and ultimately get a cleaner file.

It just seems to me that if "lens blur" or really what we're trying to say "bokeh" was an original objective then we'd not only have a much greater range of adjustment, but we'd be able to feather it out from the edges to duplicate actual bokeh.. Sure it's a nice feature, but not nearly as useful as it could be if designed from an original feature perspective.

IMO LR is a great tool, but this sort of 'half way' feature diminishes more than it adds.  I'd rather it do one thing right than five things 'kind of okay'..

On that note, I think the new raw engine is awesome.. can't wait to convert over to the release version.

Steve, I suggest you try it on a wider range of test files. This is not the sort of example that lends itself well to the defocus.
