ADOBE TRAINING, PHOTOSHOP CS6 BASICS: CORRECTING IMAGES Photoshop has many sophisticated tools to correct/replace areas in images that may be damaged or unwanted. In this tutorial you will learn to: • • • •
Use the Spot Healing Brush Tool to retouch small areas in images Use the Patch Tool to retouch areas in images using specific sources Use the Cloning tool to duplicate areas for easy correction Use the Content-Aware Move Feature to move/fill selections in images
The Spot Healing Brush Tool The Spot Healing Brush Tool can be used to clean up small unwanted marks from an image. The brush removes the marks selected by replacing it with a sample from the pixels around the area, matching the texture, tone and lighting as accurately as possible.
Step One: Open the image and add a (1) New layer to the project. All of the corrections will be made on the new layer to protect the original image.

Step Two: With the (1) new layer selected in the layers pane, choose the Spot Healing Brush Tool from the Toolbar.
Step Three: Use the Tool Options Bar to set the Spot Healing Brush Tool settings. Brush Size - will vary based on the size of the area for correction. The hardness settings at 100% and the spacing at 25% will work in most cases. Note: Really larger areas should not be corrected with the Spot Healing Tool. Try the Patch Tool instead. Proximity Match - will use the pixels in the area to make a match in the correction. Create Texture - can be used in situations where there are not enough "good" pixels around the area to be healed. Photoshop will try to create its own good texture when this option is selected. (1) Content-Aware - Photoshop will replace the area selected by the brush with what it thinks should be there if the unwanted object is removed. This is often the most effective and quickest method of spot healing images. (2) Sample All Layers - this must be selected if you are trying to preserve the original image by making corrections on separate layer, as we are demonstrating in this tutorial.
