How to erase any details in photos with GIMP

You just took a great photo, but accidentally an unpleasant object appeared somewhere on the photo, affecting the composition, or even ruining the entire image. What to do in this situation? The condition does not allow you to use Photoshop, but don't worry, there is still a way to fix this problem!

With GIMP, often jokingly called the free version of Photoshop, users can easily erase objects in the background of an image with just a few tools. This technique requires a bit of patience for best results, as you're essentially patching the object with other parts of the image, and then painting over the object to help it blend with the original background. .

Original original photo

To get started, open the image in GIMP by going to File > Open and select images from computer. The example will remove the man from the photo below.

Open the image with the object to be deleted

Once opened, zoom in on the part of the image you want to delete with the tool Zoom (choose tools Zoom from the toolbar or tap Z on the keyboard). The user can click and drag the mouse around the object to zoom in on it (shown in the image above).

Zoom

OPTIONAL: If you're worried about accidentally deleting a nearby object, you can use the tool Paths on the toolbar or press B on the keyboard and draw around the object. Draw by clicking to create an anchor point, then click and drag to bend the line at the anchor point.

Paths

Click and drag the last anchor point so that it overlaps with the first anchor point. You can click on any of the created anchor points and adjust the curves as needed. Simply click on the boxes displayed around the anchor point and drag them to the desired position.

Create anchor points

Once everything is in place (in the example a very rough sketch), go to Tool Options and click “Selection from path” as stated above. This will outline the object as a selection and ensure the user doesn't draw over anything outside the object.

The example doesn't use a selection for this image, so we'll go ahead Select > None or press Shift + Ctrl + A on the keyboard to deselect that area.

Deselect

Next, select tools Clone from the toolbar or tap C on the keyboard (pointed by the red arrow in the image above) to select an area of ​​pixels in an area of ​​the image, then draw or “duplicate” the selected pixels on the object you want to delete. Use square bracket keys [ ] on the keyboard to adjust the brush size of the Clone tool.

Clone

When you have the desired size, hold down the key Ctrl and select the area you want to get some pixels on the image (indicated by the red arrow in the image above).

Hold Ctrl

The circle representing the brush will freeze over the selected area. This is the clone area. Make sure to leave some space between the selected area and the object you're trying to erase, because the clone brush will move with the live brush (denoted by the green arrow) as you draw. The brush size can be increased or decreased after an area has been selected to clone – the cloned brush will increase and decrease according to the brush size.

Adjust size

NOTE: If you want your object/person to look like a ghost or be partially visible, you can adjust the opacity (Opacity) of tools Clone in the menu area Tool Options. Just click the bar Opacity and drag left or right, or double-click the number (shown as 51.7% above) and enter the desired opacity percentage.

As you draw, the object will start to disappear (assuming you've selected a large enough area to copy). When accessing areas that have had their composition changed, it may be necessary to repeat the clone area selection steps (keep Ctrl and click on the new area) before continuing to draw. If you make a mistake, just press Ctrl + Z to undo the steps taken.

Press Ctrl+Z when you need to undo

Readers should click Z on the keyboard then hold down the key Ctrl while clicking to zoom out and see how the overall layout looks while making changes. This helps control whether any part of the object is still visible, or if anything seems out of place. In this case, some parts of the leg are still left, and so it is necessary to re-enlarge and process those areas.

Tips: Key can be held down Shift to create straight lines using the tool Clone. The example used this technique towards the end because some of the light lines on the sidewalk looked a bit funny and blurred.

Processing notes

After processing the remaining spots, the man in the background of the original photo disappeared! Do the same to remove other objects in the surrounding area and make the photo look more natural.
