    Odd pixel

    Odd pixel
    Shooting with my Nikon DF in Raw/jpeg to have instant photos to pull off and I have this pixel showing up. It's not a sparkly on his face. It's in every jpeg at the same exact place. However, it's not in any of the raw files. STUMPED!

    Anyone have any ideas?

    Post a sample. My guess is it's a hot pixel.

    Hot pixel. Usual with higher ISOs.

    Learn me something.
    Hot pixel is what it looks like, and that is what I would have guessed, but why does it show up only in the jpeg image?

    Not all raw converters are the same. What's built into the camera can demosaic the raw data differently than an engine used in a computer app. So maybe the in-camera algorithm fails to detect it and causes the green dot, but the computer's app does and removes it.

    I thought hot pixel as well, but the not showing up in raw files doesn't make sense. And I'm not saying Sparky is wrong, but I haven't heard of Nikon cameras cancelling out hot pixels before.

    Well, then someone's got some 'splanin' to do.. When you find out, please let me know. I read up on hot pixels a long time ago, but I don't remember what I read.

    Edit: I just read something that ACR and LR maps out hot pixels whatever that means. What progam are you using?

    You never look at raw files. They're converted to jpegs so you can see them. Either in-camera or in-computer.
