Post spaccio moncler 翻拍二&#27
翻拍二法及要领
底片。下面介绍两种翻拍方法,以飨读者。放大机翻拍照片(1)将一张清晰的底片夹在底片夹内插入放大机。(2)将需翻拍的照片放在放大机压纸板上,开亮放大机电源将底片的影像调到与待翻拍相片同样大小,焦点调清晰,[link widoczny dla zalogowanych],这时影像位置与待翻拍片影像的位置重合;用3mm厚大小适中的无划痕无污迹的透明玻璃压住相片;将放大机镜头光圈调在8或1]处,并关掉放大机电源。(3)抽出底片夹,取下底片,在全黑条件下将一张未感光的胶片药膜面朝下置于底片夹中央好插回放大机(如果是正色底片可开红色安全灯),用黑布将底片夹周围遮挡起来。(4)在待翻拍照片上面1m处成45。角开一200W乳白灯泡,使胶片感光8s。(5)取出底片进行冲洗即可。注意:光圈尽量小一些,以保证成像清晰;曝光时间要经过试验。用近摄接圈翻拍照片近摄接圈可进行1t1的翻拍,翻拍时注下iiI意以下几点:(1)根据待翻拍照片大小确定近摄接圈的组合方式,具体组合及翻拍物像比如附表。(2)将要翻拍的照片用3mm透明玻璃夹住设法垂直桌面放置好,[link widoczny dla zalogowanych]。(3)将照相机(单反式)用微型三角架置于要翻拍的照片前方,镜头光轴要与照片平面垂直,光圈调至最大并调节好焦距使成像清晰,然后调节光圈至11或8,[link widoczny dla zalogowanych]。这时景深较大,[link widoczny dla zalogowanych],影像较清晰;用自拍(或快门线)曝光的曝光量要比没有加近摄接圈时有所增加,具体参阅附表。(4)用高分辩率显影液显影,[link widoczny dla zalogowanych],然后定影、水洗、干燥即可。附表用近舞接■翻拍照片条件注:1.物慷比为近似值2.曝光的倍数等于原键头焦距与接圈长度的和的平方除以原镜头焦距的平方的商(单位要统一)一辟
