Usage of the word "exposed" is in this case really correct, the similarity with the classic photographic process, or with some of its predecessors, for example - daguerreotype, is quite usable and remarkable.
Paggamit ng salitang "nakalantad" sa kasong ito ay talagang tama, ang pagkakapareho gamit ang classic na photographic na proseso, o sa ilang ng nito predecessors, halimbawa - ang daguerreotype, ay lubos na kapaki-pakinabang at kahanga-hangang.
