Well, nowadays, retouching refers to the 'touch up' techniques used by digital photographers and editors. This walkthrough is just a basic overview of the processes I went through in photoshop.
We're going to start with a simple portrait and go through some techniques to make the whole image look more professional. We'll be smoothing the skin, sharpening the details, changing the eye colours and colourising the image to give a 'retro' feel.
This instruct able does require some photoshop knowledge as i'm not going to explain where to find the various layer styles etc, but a quick google should help you!

Step 1: Smoothing the Skin
You will then need to apply a layer mask to remove the blur on the areas of the picture where detail is important - the eyes, hair, contours, etc.
Step 2: Retro Colouring
Step 3: Sharpen!
Step 4: Adding Curves
I also desaturated slightly - again, looking for that retro style.
Step 5: Now for the Eyes
Create a 'hue/saturation' layer and adjust the hue until the eyes are the colour you want them. Don't worry about the rest of the image - we're going to mask this out.
Once you have the desired eye colour you want to fill the layer mask with black (i always use command+backspace with black as background colour).
Now simply paint the eyes back in white.
I also used a similar technique to remove some of the red veins in the eyes by desaturating the image, then using the layer mask to just desaturate the portions I wanted.
There we go, that's pretty much it.
Actually, for this image there were various curve layers just tweaking individual parts of the photo, but as a general walkthrough you get the idea!
