[[alternative]]The Study on Concept of Photocollage in Visual Image by Digital Media

[[abstract]]The concept of Photocollage is commonly used in visually expressed works ,that is because after the 20th century Photollage combine two important expressed ways of vision,Collage and photography. That’s why in contemporary visual expression Photocollage is still very important for visual values. As the technology of photography is growing gradually,works which are been called “Photocollage”and “Photomotange”are also developing. As computer technology grows , computer technology conducts the digitals,which makes the innovation and changes in Visual Expression. The development of computer visual technology varies the original meaning of Photography, Photocollage and Photomontange.By the assistance of Computer Technology , the expressive ways of Photography becomes more varied so that the expressed ways of Photocollage and Photomontange could get out of its previous limited expressive ways and freely express its original concept by computer virtualeffects.Perhaps the works which are catalogued as Photocollage and Photomontange don’t really mean the same as before,but the strongly impressed visual effects, the way showing space and time, and combining and connecting things uncontinuously from different sources,those make Photocollage still have the value in visual expression. This study is based on understanding the idea and purpose of Photocollage , and according to its concept, spirit ,style and particular uses to start on estimating and analyzing it. From its original sources to contemporary visual arts and designs, this study analyze and estimate through ,then try to catalogue it for photography-design work reference. In the end of this study, I will add up the results of analyzing and estimating in Photocollage and what I have learned from it into my personal work to balance the theory and particular uses of Photocollage.
