It happens that in the taken photo the photographer is interested, first of all, the subject of photography, but the background is subject to an indispensable replacement.
Once such manipulations with photos were available only to photomontage studios, and now it is under the power of anyone who has the program Photoshop.
Open the photo with Photoshop.
In the right part of the screen, in the layers palette, double-click on the icon of your photo.
Click the "Image" button at the top of the window and select the "Snippet" menu item.
Select the Marker tool.
Carefully circle the outline of your object.
Select the Fill tool and fill in the part of the image you want to select from the background.
If necessary, retouch the resulting image.
