포토샵 작업중 배경유지 하는 방법 알려주세요

포토샵cs6 에서 사진작업 중

crop을 사용하면 layer이력에서 배경이 crop이나 layer로 바뀌네요.

계속 배경(background)였으면 좋겠는데요. 혹시 방법 있으면 자문구합니다

Crop is a document feature all layers are cropped.  Layers can be any size.  Can be larger then canvas size and even be positioned off canvas.  None will have pixels off canvas if you crop the document.   You work on a layer's  size with tool likes Transform and selection tools you can select pixels areas and delete/clear the pixels in the selected areas so in effect you can trim layers.
