What causes highlights .....sky blinking....and how can I avoid this..

Have I selected the correct section?

The "blinks" are just a warning that that area is close to or beyond overexposure. You need to evaluate whether, in the context of the whole image, if that is acceptable. If it is the sky, in order to bring that into the range of a proper exposure, you will most likely UNDER expose the rest of the image.

In the specific case of the sky, is the sky important to the image? Is it a large part of the image? Would getting detail in the sky mean underexposing the subject? Would a split neutral density filter to hold back the sky be worth all the trouble and expense?

The blinking highlight is not something you necessarily avoid, it is something you have to take into account and evaluate. Blinking on a chrome part of a car and on someone's face are two different things. One is no big deal and one is not acceptable. Well....not usually.

Thankyou Captain C it is the sky which has been affected and is not a priority in the. Pic.
I shall take on board your comments

I hate those blinkies, so I turn them off. As the Captain said, if that area isn't the main concern, ignore them. Sometimes it's not possible to have everything exposed perfectly. PP can often improve overexposed areas.

Try to dal in a little exposure compensation like -1/3 or -2/3. That won't underexpose your photo to much and it may bring back some detail in the sky. (clouds). If its just a bright blue sky maybe rethink the shot and take the sky out of the photo

Bkh, Jerry is right, TURN those blinkies off. If you don't, when you print that photo it will keep blinking, very annoying, I hate it when that happens!
Bkh, no, really, I always leave both of my red/blue blinkies going all the time. Tells me when I'm getting into trouble. Then as the captain says, make some decisions. Just so you know, almost always, a shot with the sun or other strong light source creates a High-Dinamic-Range scene or HDR situation. Digitals can't handle the range, that's why they come equipped with those waning sensors(blinkies), kind of like a temperature/oil gauge on a car.
That's why there are a lot of lively posts on HDR and what/how to do about it. Look in the HDR posts section to learn how to start dealing with those situations. With HDR they can be fully controlled/solved but it may not be for you as it is not for many.
Good luck with your blinkies, they are only there to help you perfect your shot.
