Blurs and Blemishes



After learning content aware fill we learnt how to use the spot healing tool. The spot healing brush tool follows a similar process as the content aware fill by sampling around the target area but instead blending the pixels from the sampled area seamlessly with the target area or in other words the texture from the sample area is blended with the color and luminosity surrounding wherever you paint.

This tool can be very useful as it allows you to remove image imperfections such as scratches, blemishes, etc. By taking a sample of the surrounding area or using a predefined pattern you can blend the imperfections into the rest of the image essentially removing the imperfection.

We then had to put what we knew to practice so we got a picture of Morgan freeman and were asked to remove some of the blemishes on his face using the spot healing brush tool. First I selected the tool from the tool bar and selected an area I wanted to cover then just clicked over it you also want your brush to be a little bigger than the blemish but not big as another a blemish might be in the brushes radius as it might sample some of the pixels from that. If that happens it might create a new more distorted blemish because of it so you want to make sure it only sample a similar area very close to blemish so it blends well.










We then learnt about Gaussian blur and how we could you use it in this case we used to help reduce certain details such as wrinkles on Morgan freeman’s face realistically so not removing or covering his wrinkles but reducing the detail and making them less visible or definitive.

to do this we duplicated the layer of Morgan free man without blemishes I then went on Filter>Blur>Gaussian blur and lowered the radius to around 2 pixels. I then added a layer mask changed the colour from white to black essentially inverting the mask then I selected the brush tool lowered the opacity to 20% and started blurring the area that I wanted to reduce the detail on such as under the eyes and on the forehead making the wrinkles less definitive.
