Hot pixel mapping - yes or no?

    I am querying this in an ongoing support case for my 1dsII 'stuck' pixels. v4 and v5 standard seem to deal with a few but not most of these. If your camera is supported and you like C1 you can do as I do - run the raw files through PixelFixer in which you map your stuck pixels and batch apply to your raw files - works and is free and brilliant. Then use C1. Like you I find Lightroom v2.5 or 3 beta detects and removes all my dodgy pixels. I still prefer certain aspects of C1 - GUI - detail & colour

    My suppoet case discussions on this over the last year have been prompt and helpful and in the case of my cr2 raw images have produced a positive outcome.

    Hot / stuck pixels should be removed with C1 but the threshold at which this operates resulted that most of the ones on my 1dsII were not. ver 5 has a new 'long exposure' noise slider which seems to change this threshold and a slider setting of 50 removes all but one, 97-100 gets the remaining one. On normally exposed images (1/15 sec - 1/2000) in other words not a 'long exposure' I see this slider having no detriment to the rest of the image at 100% view.

    Find the slider value which works for you and set this as the default to be applied as images are imported. Hopefully should remove all stuck or hot pixels.
