Troubles with AutoSelection of AutoProfile area ...
Posted: Fri Jun 06, 2008 2:51 am
Hello,
I've been using NeatImage for nearly five years now and I'm very happy with the steady increase of speed and quality that has been incorporated into the software. Overall I consider myself very proficient with the software and have integrated it into my workflow software via the command line to automate the processing of the 10s of thousands of images we have to retouch each year.
I photograph indoor volleyball extensively and each event sees us commonly processing thousands of images photographed at anywhere from ISO 1600 - 6400. Often with excellent exposure, but under those fun convention center lights which fluctuate in color and exposure between each frame, making a standard noise profile impractical due to constant changes not just in exposure but WB, both of which are corrected in the RAW conversion stage.
I use Bibble to convert my RAW files and have purchased the version of NoiseNinja to possibly integrate my noise reduction straight into RAW conversion, but find that I MUCH prefer NeatImage's interface and results.
However, I have noted that NI's selection of the area to be auto profiled is heavily biased to the highlights. It has been so since the feature was added and I've never been able to make sense of this. Noise is minimal to low in the highlights and anytime NI selects a highlight to profile, I get a bad image as a result, which I need to manually reprocess. With convention center lights splashing onto background walls, it is not uncommon that I get a large highlight region in the background of an image that causes the AutoSelection function to choose poorly.
Is this simply because NI is mistaking the highlight region for smooth featureless regions and mistaking midtone and shadow areas of no detail (but with noise) areas of high frequency noise?
The problem I am running into is that having to stop my processing workflow to go back and reprofile and process random images throughout an events worth of work is very time consuming and disruptive to the processing workflow.
Is there any way to bias the tonality of the region NI looks to AutoProfile?
Thanks for great software.
Regards,
Micheal
