Let your photos 'shine' with GIMP's background change feature

It's easy to change the backgound of a photo in Photoshop, but you don't want to pay the expensive cost for that, so GIMP will be a wise choice. Changing the background in GIMP is very simple and there are many different ways to do this. The following article will introduce two best solutions to help your photos 'shine'.

Before start

If you are a new user of GIMP, it may be a bit awkward with its unusual user interface.By default, GIMP is set up with each interface element - windows, toolbars, palettes, etc. - separate.

To view GIMP with the traditional interface, selectWindows> Single-Window Mode,separate parts of the GIMP interface will be joined together like the one you normally use.

Use the Foreground Select tool to separate the background

One of the quickest ways to change the background of an image is to use the Foreground Select tool.This is a semi-automated tool that does most of the work for you, but it only works well on some photos.

Determine the edge of the image you want to take and clearly separate it from the background.Highlight the entire previous contrast - tones or colors.

Open the image and select the Foreground Select tool from the control panel on the left side of the screen.

1. Draw a border

First, draw a rough outline around the object to split the background by clicking, dragging, or combining both.This outline does not need to be accurate.All you need to do in this section is to define the image area that contains the separating element and the background.

After the selection is complete, you will see a dark blue layer on the background and a lighter blue layer on the rest of the image.You can change this color to green or red inTool Options.

2. Draw on the image to be separated

Now, draw a line on all the parts of the image you want to grab, taking all of its different colors and tones.Make sure you do not encroach on the background - because this operation cannot be undone, you will have to start over if it is wrong.

When you release the mouse button, GIMP will start analyzing the image, which will take several seconds.When completed, the image area contains the element to be retrieved and the background area is no longer segregated.If any part of the object to be retrieved is not selected, just redraw it to add.

Drag the extracted image into place using theMove tool (use the M shortcut) to finish.

Use the Paths tool to separate the background

For any image that the object you choose has a blurred edge or many details, automated tools will not work.You need to usePaths tool .

GIMP's Paths tool is similar to the Pen tool in Photoshop.This tool will be a bit difficult to use, but it is an extremely powerful tool.

How to use Paths tool in GIMP

Paths tool allows you to create complex selections by placing a series of dots, called buttons, on top of an image.They are connected by a line that can be straight or curved or angled.By placing buttons around the object, you can select it correctly.

When placing a new button,click and drag in the direction you wantand quickly create the curve.

You can adjust the button at any time by clicking the button to select, move to a new location or delete the button with the Backspacekey.Make sure you select the last button in the path before you start adding other buttons.

The above instructions are very simple but may take some time before you feel "comfortable" with it.You should practice in a white image file to get used to how it works.

When you want to cut off an object with the Paths Tool , you position the buttons along a line around the edge of the object to be taken.

1. Zoom in
