Excessive illuminance and sunscalds
Superfluous illumination is harmless (unless obvious sunscald) however the plant loses visual appeal.
Symptoms of surplus light: leaves become light (up to whitish), burn out on sun; the plant loses decorative effect. Leaves of deciduous plants grow smaller, that affects appearance.
The help: gradually move a plant away from a light source, or use the filter (a paper or a reflecting barrier on a windowpane, a tulle curtain, gauze). Do not move a plant from the bright sun in a deep shadow at once - it can shed all leaves.
If you have noticed sunscalds on leaves, you won’t be able to restore them any more – wait for new sprouts.
