In this assignment, I took my photo in same position with robocop and then I used the lasso tool and placed the part I wanted to use from robocop. Then I used the mask and erase the part I wanted to show. Last, I took a photo of the wall in my room and adjust it. I used the adjustment layers such as levels, curves, Brightness. I placed the wall into my image and used the mask again to show my original image.
