It means to be submerged in a lower spot. Image pixels have a numerical value. High value would be bright. Low value would be dark.

It's a common problem with digital cameras that a bright area might wash out the image, or a dark area become darker because of too much contrast. Our eyes are much better than a camera in "balancing" an image so that we see what we want to see without glare or contrasting darkness.

The word 'sunk' is not a noun. It's the past participle of 'sink'.

'Details may be lost in glare or (may be) sunk in a dark spot.'
