I've been looking all over for this answer. I've seen many videos out there that talk about what's known as "blinkies" for Canon cameras. These are the highlight alerts or highlight warnings to blink when you review your photos. If one area of a picture is overexposed, the area that's pure white will blink and if it's underexposed, the pure black area will blink. I took a few demo shots and can see areas that are blinking when I'm in the review mode, but I can't see where to turn this feature on and off. Does anyone know where I can do this on my Canon Rebel T7i (800D)?
