C1 is unable to deal with Panasonic GH2 dead pixels.
Unfortunately, so rare is the natural pattern of dead pixels on the Panasonic GH2 (they tend to die in pairs with their neighbors) that even with NR Single Pixel set to 100%, C1 can't get rid of them.

Now, I've found this to be such a non issue in a lot of Converters like Lightroom or even non specialized RAW viewers like ThumbsPlus 7 or FastStone Image Viewer 4. I don't really know what's going on there, I know the camera maps out dead pixels but unlike Olympus it doesn't fix them in the RAW file. Are they still listed in the RAW file for the converter to do what it sees fit? Or are those converters just intelligent enough to detect them and map them out automatically?
Anyway this was such an important issue that someone bothered to program a tool based on DCRAW http://forums.dpreview.com/forums/readf ... 126&page=1 to address those pixels right where it's needed: in the RAW file itself. I tested the tool and it worked very well on a copy of the file but when I load the copy on C1 that's when all Hell breaks loose, with the fixed file showing 100x more pixel problems than the original and on top of that, a lot of burnt highlights. 🤬 http://farm8.staticflickr.com/7223/6887512580_b43691d99c_b.jpg Now what bothers me even more is that I know C1 doesn't like RAW files being tampered but this doesn't happen with any other RAW converter I tried where the method really worked wonders... 😡 Why is C1 making a mess of that file?
The only workaround I've managed to use so far is this: http://farm8.staticflickr.com/7139/6887535280_6cf9ba6ec0_b.jpg Does it work? Yes, but being overkill is an understatement. Since the minimum radius of the spot removal tool is 5 pixels, C1 is cleaning more than 3500 pixels when it should just address 45x2=90 at most!!! Now, to add insult to injury we all know the GH2 has a multi-aspect ratio sensor which means I would need 4 (a 4:3, a 16:9, a 3:2 and a 1:1) Spot Removal profiles to clean my images. Not only that but I need to selectively apply those profiles according to the aspect ratio of the picture. All in all this is becoming a major pain.
Does anyone know of a simpler way of solving this dead pixels issue?

My experience is that CO6 often automatically removes dead pixels on conversion. Long story short, do not contemplate them from the main Viewer but from the RGB output.
So my question is, are the dead pixels still there after processing?0 -
Sorry to report but they do make it to the output.
If you care to try here is the RW2 file with it's correspondent in-camera generated JPEG.

Please disregard this bug report.
This was happening on an earlier version of C1v6 which I never cared to update. Tried the latest version and apart from a very few stuck BLUE/GREEN pixels the real DEAD black ones get mapped out automatically.
Thanks again for such a great product.0
