image description is generally great, but not in all situations, camera is an example. one can't even pause or turn it off temporarily. i went to settings > accessibility > voiceover > voiceover recognition > image description and deselected camera from the app list, and it still on.
trying to concentrate to take a good picture and have voiceover saying something like "woodwork, drawing, cabinet, sofa, glassware, coffee table" continuously proves to be very distracting.
if you are in the same boat, have you found a way to temporarily pause it?
