Firstly I took the photo of the rose with a black B/G. To darken it more I cut around it with the lasso tool went to Select-inverse then changed the colour to black in the foreground box and used the paint bucket to drop in the black.I then went to file-blank file and brought up the size I wanted. I changed this to black.I clicked on Rectangular Marquee tool and placed a box around the rose pic. Chose Ctrl C and brought up the blank box and chose Ctrl V. I placed the pic in this box with room down the bottom to add the flood filter.
Fuji S9500 used.
