There is a simple method of removing blemishes and color noise in images in Photoshop.
Step 1 : I have opened this high resolution, free stock image in Photoshop. A closeup of the top image at the bottom makes the blemishes and color noise quite evident.
Step 2 : Press CTRL+J. The Background image duplicates into Layer1.
Step 3 : Go to Filter>Blur>Gaussian Blur.
Step 4 : The Gaussian Blur dialogue opens. Set the Radius to 25 pixels. ClickOK.
This is how the image looks.
Step 5 : In the Layers pallette change he Blend Mode of Layer 1 to Darken.
Step 6 : Lower the Opacity of Layer 1 to 30 % by dragging the Opacity Slider to the left.
The image looks like this.
Step 7 : Press CTRL+J. Layer 1 duplicates into Layer 1 copy.
Step 8 : Reduce the Opacity of Layer 1 copy to 60 %.
Step 9 : Change the Blend Mode to Lighten.
Step 10 : Press SHIFT and click on Layer 1. Both layers are highlighted.
Step 11 : Press CTRL+G. Both the layers are compressed into Group 1.
Step 12 : Click on the Add Layer Mask button. A layer mask forms on Group 1 layer.
Step 13 : Click on the Brush Tool. Make sure that the Foreground Color is set to Black.
Step 14 : Click where the arrow points to in the top panel. Set the Hardness to 0 and Master Diameter to 25. (The Master diameter will depend on your image).
Step 15 : Use the Brush to paint on the eyes. The blurred effect will be cleared.
Step 16 : I have painted over the eye with theBrush Tool. It has regained its sharpnes..
Step 17 : I have used the Brush Tool on the other eye.
Step 18 : I have used the Brush Tool on the nostrils and the lips. Both have regained sharpness.
The color noise and the splotchy skin has gone. That is all.
