Might be an overanalysis, but I've been shooting a lot of stills on my GH4, and because I normally edit in ACR+Photoshop (for which there is no GH4 RAW support yet), I've pretty much been jpg's only to this point. I decided to give Iridient and PhotoNinja a go earlier today, and I had some strange discoveries. In both programs, at between 100% and 200% view, there are what looks like dead pixels throughout the frame (maybe 10-15 scattered across). They look like this: http://imgur.com/FxCJ8rl http://imgur.com/5H2RGHU And at first I thought I just needed to run the pixel remap, which I did a couple times, to no avail. All spots still there, still in the same position. So then I started to worry that maybe I had a serious dead pixel problem which would show in video, so I shot a bunch of different stuff at 4K, cropped way in, and the image was clean as a whistle. So then I got curious, and I started downloading every other RAW GH4 photo that I could find (a whole range of ISO's and shutter speeds) from five different sources, including a couple Spanish sites and imaging-resource. Here's what I found on imaging-resource, and every other site (marked with arrows, might need to zoom in a little): http://imgur.com/h1sMlyG Link to download: http://www.imaging-r...sonic-gh4A7.HTM Every single RAW photo from six different GH4's has this black "noise" in it, at shutter speeds from 2 seconds to 1/8000 and ISO's from 200 to 3200 (high as I looked). It looks like dead pixels, and it responds to the dead pixel filter tool in Iridient, but it's weird, because it's pervasive throughout every single photo from every camera I've seen. Is it possible this is an artifact from the GH4's image processing, or perhaps a hitch in the way Iridient processes images? For what it's worth, some of these spots (though not all) also show up in Photo Ninja - this is, again, true for all six cameras, every single photo. Any thoughts, anyone?
