This how to video will show you how to remove blemishes and do other touch ups in Photoshop. First, open the image you want to touch up in the program. Now, choose the polygon tool and select the background of the image. Now, go to adjustments and change the brightness and contrast. You can also add a blur in the filters. Use the smudge tool to touch up any errors from using the blur filter. To fix blemishes, use the patch tool. Select the area you want to fix and drag it to an area of similar texture. Zoom in to do this accurately. To fix shines, select a paint brush and select a near by color using the alt key. Now, paint over it with a soft brush. This will reduce the shine. If there is red eye in the image, select the iris of the person and lower the saturation of it. This video shows you how easy it is to touch up photos.
