Understanding the BLINKING areas

Is it normal to use AUTO mode or even under MANUAL mode but accepting the metered values to have highlights/dark areas blinking?


I thought it was pretty weird to take a photo under auto mode and still have blinkies.


How does the blinking work?


TIA!

No matter what the mode, there will always be circumstances where it's impossible to have everything properly exposed.

Right. Any time there are a combination of extreme light and extreme darkness, there is no way to expose them both properly. I suppose it would even be possible to have white blinkies and black blinkies in the same image, though I have not encountered it. Well, I guess in that case the auto would compensate on one end (probably the highlights).

I would think it would depend on exactly what metering mode and what you were metering on. Certainly possible

Blinks are intensities outside of the dynamic range of the image sensor (overexposed or underexposed) and thus losing detail. Sometimes it's okay to overexpose. For example I will be willing to lose so sky detail if I'm more interested in the foreground. Prevention? Outside of exposure tweaking their's ND gradient filters (not experience here, but I see them work wonders) and HDR (played with a little, can work well if you plan ahead).

Both will show up under certain back light situations. I don't worry about the yellows, it's the reds that I watch. On tiny, single pixel flashing red seems to be the exposure I prefer. Poor man's ETTR, I guess.

I wonder if the "blinkies" work just on brightness. I guess it would be even better if they went off if any of the RGB channels were saturated.
