一张底片,以软片拷贝一张透明正片,叠合在一起,向一个方向(一般沿底片对角线方向)平行移位,略为错开,并使之固定后晒印或放大,则平面感光纸上的影像,会获得阴阳凹凸感的视觉效果,获得类似浮雕的照片。这种方法称为“双重影像法”,其实称“正负单向错位叠影法”更为合理。对拷贝片的局部涂红遮挡,不论是黑白片还是彩色负片,都可加工成局部浮雕式影片;对拷贝片的密度、反差及微粒诸因素的控制,还可加工成具有泥塑、石膏、红木等特殊材料质

A negative film, with a soft copy of a transparent print, stacked together, to a direction (generally diagonal direction along the film) parallel to the shift, slightly staggered, and make it fixed after printing or enlargement, the plane of light-sensitive paper On the image, you will get a sense of yin and yang bumpy visual effects, access to similar relief photos. This method is called “double image method”, in fact, called “positive and negative one-way staggered superimposed method” more reasonable. Part of the copy film coated with red cover, either black or white film negatives, can be processed into a partial relief film; copy film density, contrast and particle control of various factors, but also processed into clay, plaster, mahogany, etc. Special material quality
