passage 25 内战时期的照片史料不如版画

★★

①Because the American Civil War coincided with technological innovations in pictorial recording and reproduction, it was perceived through new informational forms—engravings and photographs. ②Historians have emphasized the photograph, retrospectively attributing significance to its representational detail, clarity, and authenticity. ③But the possible subject matter for photographs was limited by the extremely slow exposure time and precarious development process of the period. ④Moreover, the limitations of pictorial reproduction made photographic salons or were distributed in albums and stereograph cards. ⑤Photographs stand as invaluable pictorial records for historians; for the public during the Civil War, however, the engravings in the illustrated press outweighed in their accessibility and immediacy the comparatively expensive photographic albums and cards.
