    Default Weird problem...

    I noticed today that on my camera's display, my camera often will 'blink' indicating blown highlights; but when I download those images, they don't always show up as blown in Digital Photo Professional (Canon's RAW utility). Any idea why that would be? If I look at the histograms in DPP, there don't seem to be blown portions on some of these images, and when I turn on DPP's highlight alert feature, the same images don't show as being blown, either. It's very odd.

    Is it because it's your highlight warning? I thought I read that the camera will warn you if your highlights were about to be blown? Could be totally off though?

    Yes, it's my highlight warning, but the thing is, the same image doesn't necessarily show as having blown highlights in DPP, which I find very odd. Which one is right? By the histograms it seems DPP is right, but why would my camera be wrong?

    It could be that the camera is reading a JPEG version instead of RAW.

    That could be it, because the camera does read the JPEG on the display, not the RAW. Though I'm not sure why there'd be a difference regarding the blown highlights, even so.

    At this point, I'm just not trusting the camera and am checking in RAW, but it seems odd to me.

    Well, the good thing is, it's better to bring down the highlights because of overexposure than to correct an underexposed image!
