The photo here gets rid of the color in the back round but keeps color on the bottle to show that all the focus on the bottle itself. What I did is I used the quick selection tool and selected the bottle to keep the color. Then I changed the background in black an white.
Black and white with a tint also a blur in the background. This creates more of a focus on the bottle. I selected the bottle putting a tint on it also in the background the car is a bit blurry so you cant tell what the license plate is.
Blur but sharp on the bottle. By selecting the background everything is blurred out that way everything else can be more in focus on the bottle it self.
Black and white but color on the bottle. Same process as the first picture.
