Today I invited my photographer friends to take outdoor shots with me. I rarely use professional cameras, so I need to ask some questions during the shooting process. The purpose of this shooting is to take some mottled marks and use it as a picture filter. I will superimpose these mottled traces on the pictures I originally took, creating a sense of old, mottled, and faded memory. So today I went to a very old place, the suburbs. The suburb is an abandoned, far away area that is gradually forgotten by people. Many years ago, something that people do n’t know may have happened here. I think this is a good place to shoot “traces”.
