基于放大纸上涂布了一层卤化银感光乳剂、粒子细、性能稳定、反差因纸号而异及成像清晰等条件,故试用它代替电子感光板拍照。放大纸裁成与底板同大,装在底片卡内,相纸要平,边不翘起来,不然推片时易卡住;拍照前调好焦点,亮度开大,荧光屏挡板启开后让影相直接打在相纸上,曝光时间为3秒,暴光完关闭挡板。冲洗步骤与相纸显影一样:在显影液中显至色调合适了取出水洗、定影、上光、就得到照片了。其优点为:(1)可连续拍多张照片,需几张就装几张相纸卡子,如需留底片就在后面的卡子内装一张电子感光板,这样同时冲洗,底片、照片同时都得到了,欲放大时再用底片放大,不过放大的效果
Based on the enlarged paper coated with a layer of silver halide emulsion, fine particles, stable performance, contrast due to different paper and imaging conditions such as clear, so try it instead of electronic photo plate. Enlarged paper cut into large with the floor, mounted in the film card, photo paper to be flat, the side does not tilt up, or easy to push the film stuck; take good focus before taking photos, open the brightness, the screen bezel after the opening Photo directly hit the photo paper, the exposure time of 3 seconds, the exposure finished closing bezel. Rinse steps and photographic development of the same: in the developer to the hue is appropriate Remove the water, fixing, polishing, to get the picture. The advantages are: (1) can take multiple photos in a row, the need to install a few sheets of paper clips, for leaving the film in the back of the clip inside an electronic photosensitive plate, so while flushing, negatives, photos at the same time Got, to zoom in and then use the film to enlarge, but the effect of amplification
