Automatic hot pixel / dead pixel removal

Hot pixels are annoying. Especially when i focus stack they create pixel trails on stacked image. It would be great to get rid of them automatically at the begining.

    Why would a camera have a hot pixel?
    If mine did I would send it to be repaired.

      It’s an issue related to temperature. Try shooting a thousand photos one after another with long exposures. You’ll have lots of shiny dots. Time lapse, astrophotography or focus stacking works require a large number of photos, long exposures and the sensor temperature rise rapidly.

      As Guray says they happen naturally at higher ISOs and they come and go on the sensor.

      I like this idea. If you’ll entertain my thoughts for implementation: do it sort of like the dust detector in LR — have an overlay that looks to find them and mark them — typically they’re either a single pixel or show up as a cross due to the Bayer filter. Let the user exclude any false positives and then blend the rest into their surroundings.

    This is a show stopper for me. I do a lot of Aurora photography. I downloaded the demo and tried to process some past aurora shots. The end result is unusable without hot pixel removal.

    I see a lot of hot pixels when I am shooting many macros for stacking.
    as is, I need to do a lot of touchup (might also be my technique).
    would be nice!

    Never saw them until Photo RAW. LR removes them automatically and really hope for the same functionality in PR.

    A big +1 to this.

    A lot of users transferring from Lightroom would be unaware that it does this behind the scenes and could either be very disappointed or caught unawares because they wouldn’t know that they would now have to manually edit those areas now. Might even think it was Photo RAW adding the sites if they were unaware of hot pixels.

    Might be nice to be able to switch the feature on and off though to be able to check the state of the original file.

    Also a +1.

    I’m relatively new to photography. I just switched from Lightroom to On1.
    Like Peter said, it’s disappointing. Long exposures are now back to double the processing time.

    Hot/dead pixel removal would be a nice capability to add as as filter in Develop with the ability to adjust the level sensitivity a little. However I’d rather positively choose to have this applied rather than it be automatic and out of my control.
