Filter or create smart collection for certain LR settings

[MarkNicholas]

During the editing of my thousands of photos I have gone through different phases. In the early days I applied certain sharpening and noise reduction setttings. I am aware that some photos have no sharpening and no noise reduction applied.

Rather than wading through one by one to identify which ones I was wondering whether anyone has found a reasonably simple way of filtering out photos with say zero sharpening setting or with zero noise reduction. To be specific it would be nice to be able to filter out photos with a luminance of say between ' and 25. Is this currently possible or are we going to have to wait for LR4 ?

This is certainly doable outside of LR using a Query on the SQLite tables contained in the catalog. I don't know the table relationships well enough to construct the query, but I can see tables that contain Luminance Smoothing and Sharpening , etc with valueStrings. Since the data is there I would think it possible that a plugin could be developed Create a Smart collection.

Thanks Cletus. I thought it might be the case that it could only be done outside Lightroom. Unfortunately I am not sufficiently competent with data bases to be able to take it any further.

[/quote] Still, I think it is a need worth filling. One of the current weaknesses of the Smart collection is the limited number of image attributes that can be selected for a filter. Perhaps Plug-in development is a way to bridge that gap.
