6.4 Repairing parts of photographs

Sometimes there are small blemishes over parts of a photograph or image that you wish to repair. For example, you might want to cover a freckle or bruise on a photograph of a person, or remove scratches from the paintwork of a car. Photo editing programs provide many tools to do this. We will look at two here: the spot healing brush tool and the healing brush tool.

Skills practised
  • Editing images
  • Spot healing brush
  • Healing brush

The spot healing brush tool is a quick way to replace blemishes with areas from close to the problem area.

  1. Load Photoshop and select OPEN from the FILE menu. Access the image data file downloaded from the above link.
  2. Notice that there appears to be a white scratch along the rear of the car near the fuel cap (it is actually a reflection). Let’s remove it to avoid confusion.
  3. Select the SPOT HEALING BRUSH TOOL from the Tools panel.
  4. In the OPTIONS bar set the BRUSH SIZE to about 20 px and the HARDNESS to 100%, then set the Zoom to 200% by pressing <Ctrl+> or <Command+> and scroll so that the fuel cap of the car is in view.
  5. Drag the SPOT HEALING BRUSH across the white lines a few times to remove them.
    Note: You can increase or decrease the Brush Size using keyboard shortcuts. Press the Close Square Bracket key <]> to increase the size of the brush. Press the Open Square Bracket key <[> to decrease the size of the brush.

  6. Press <Ctrl+0> or <Command+0> to return the view to FIT ON SCREEN to see the effect of the adjustment.
  7. Save the file in your storage folder if you wish to then close the file.

The healing brush tool

The healing brush tool is more accurate for repairing images because you select the sample area to be applied to the blemish, so if the spot healing brush tool does not do an adequate job, the healing brush tool can be used.

  1. Reload the original version of the file downloaded above.
  2. Zoom to 200% and scroll to the fuel tank cap.
  3. Select the HEALING BRUSH TOOL from the Tools panel – it is within the SPOT HEALING BRUSH TOOL.
  4. Press the [ key until the brush size is reduced to about 5 px.
  5. Move the point to the dark blue area above the white in the fuel cap, hold down the <Alt> or <Option> key and click the mouse button to select that area.

Skills practised
  • Duplicating layers
  • Applying filters
  • Spot healing brush

The skin complexion in a photo can be enhanced to reduce blemishes and spots so that the skin looks smooth.

  1. Open the image data file downloaded from the above link.
  2. TS0615.png
    A duplicate of the layer will be made so that major changes can be made to the copy without affecting the original image. Press <Ctrl+J> or <Command+J> to duplicate the background layer.
  3. Double click on the new layer label in the LAYERS panel and change its name to ‘Softened’.
    TS0616.png

    Note: You can also select DUPLICATE LAYER from the Layer menu to duplicate the layer.
  4. The duplicated layer will be blurred to give the skin a softer, more even look. After this, sections of the image such as the eyes and mouth can be sharpened.
  5. Display the FILTER menu, highlight BLUR and select SURFACE BLUR.
  6. Click on the ZOOM OUT icon to reduce the view to 50% so that you can see most of the face then set the RADIUS to about 8 pixels and the THRESHOLD to 8.
    Note: In the PREVIEW box you can scroll the picture around. Click and hold on the image in the PREVIEW box and the original image is displayed. When you release the mouse button the effect of the blur is shown.
  7. Select OK and the tone of the skin should look softer and smoother.
  8. Select the SPOT HEALING BRUSH TOOL from the Tools panel and click on any blemishes on the face to remove them.
    Note: If the blurring is too artificial, you can reduce the Opacity of the Softened layer so that a little of the Background layer is seen through it. The OPACITY box is at the top right of the Layers panel.

  9. You can turn the visibility of the softened layer off to see the original image then turn the view back on.
  10. Save the image in your storage folder as a Photoshop file under the name: Face.

Sharpening facial features

Skills practised
  • Layer masks
  • Painting a mask

Painting on a transparent mask to display the original features through the blurred layer can highlight important parts of the face such as the eyes, eyebrows, mouth and hair.

TS0618.png
  1. With the Face image open, select the SOFTENED layer and click on the ADD LAYER MASK icon at the base of the Layers panel to add a mask to it.
  2. Select the BRUSH TOOL from the Tools panel and, in the options bar, select a 15 px brush and NORMAL mode.
  3. Set the FOREGROUND COLOUR to black, paint over the eyes, eyelids, mouth, nostrils and hair and those parts of the image from the background layer will become visible hence look a little brighter.
    TS0619.png

    Note: By blurring the image we have set the skin tones to look more consistent and then sharpened the important parts of the image. You should see the areas you painted in the Mask thumbnail box next to the Softened layer.
