We presented many photographs of Obama one at a time, so people did not realize that what we were changing from one photograph to the next was whether we had artificially lightened or darkened his skin tone.
Мы показали много фотографий Обамы по одной, поэтому люди не замечали, что на разных фотографиях мы либо высвечивали, либо затемняли тон его кожи.
