    dp1 dead pixels in awb mode

    discovered this looking at the wet roses. the day before i'd shot in cloudy mode. examined a bunch of them and no dead pixels.

    not consistent in awb. sometimes the pictures fine. i suspect certain glints of light must come up dead. or the camera hot from the shot.

    that's why they come up as defective when i load them as tiffs from pro 4 into photoshop. again, it only happens with some, however still a lot.

    anybody discovered this? i know we had a discussion about the defective file warning before.

    sample. all the white spots.

    ps. just checked another set from several days ago, shot in cloudy mode on a cloudy day. no dead pixels. or would these be overblown instead of dead? or could it be something to do with the closeup lens picking up sunlight?

    well, it looks like i may have jumped the gun. just pixel peeped on more than a dozen of the ones that come up with the warning. some darker ones say it and they've no white spots. i guess i've been looking at tiny reflections off water as the cause of the signal. that said, a whole string of them will come up with warnings, then a whole string without. the mystery remains.

    thanks,

    The mysteries of DP1 are seemingly endless, Wayne. Maybe that is one of the reasons why we like the little devil...

    Wayne that's nearly an optical illusion, had to go large to prove not, even then at first glance looks like a old boot.
    Or is it me lol.

    it looks like i was getting a superfluity of 'hot pixels.' here's a free plugin to deal with them:
