Step 1: Preparation

In the Beginning we have to isolate gold frame around scanned picture from actual image part.

Next our task is to detect and capture original details as soon as possible. 
We will use Curves Tool to sharpen the image and bring back the face's edges.

Step 3: Image revision

The comprehensive analysis is the first step toward success photo restoration 
The correct expertise can help you save hours tedious work because even little errors in the beginning will accrue from step to step and finally person may become no longer recognizable.

So before you start to restore, be sure what is wrong with the photo and how final image should looks like .

Although the image is badly damaged all facial features are still clearly recognizable
The image includes combination of fading :
- lost contrast;
- some mold stain;
- large number of scratches as result of polishing process.

After contrast adjustment we also can see result of the negative impact :
- damaged facial shapes and volumes;
- broken the edges of jaw lip eye;
-lost the texture of skin , hair and dress.

The General Workflow

The restoration process should go from large to small from general to specific. It is vital to fix the proportions and major shapes
before adding details.

The general workflow may includes the following steps:
- Softening up most glaring blotches using the Dust & Scratches filter
- manually cleaning up all the dirt and fix image' shape with clone-stamp 
- repairing the edges with brushing along the edges with the 
- replacing damaged details with content from another image
- adding definition to the face details

The Restoration Method

The method we use can be found in many resources . This technique of selectively applying processing treatment commonly used for removing dust, scratches, stains and other small defects.
We improved this method by adding some more steps to restore heavy damaged images.
So that we have two opposite tasks - smooth shapes and sharp edges
To solve the tasks at first we correct entire image in various ways and then by using the History Brush apply the treatment over image without additional distorting image' edges

Select Channel Mixer as the source for History Brush

The History state can also be temporarily saved as Snapshot 

Some later we will revert and use the state as the Current State to work on .

Step 2: Smoothing Shapes

As you can see, the image is mix of artifacts and useful information.

So we are required to clear the artifacts , smooth face ' shape and make soften transition between lights and shadows , while keeping them separate

Keep in mind the direction of light and where shadow and highlight should be located

Next we'll add some noise and apply Gaussian Blur gaussian blur to simulate skin texture.

To keep the image from looking too plastic, you’ll need to add more texture to the skin.

Now we are ready to use History Brush

Select the Channel Mixer state as the current state to work on, and gaussian blur set the source for the History

To restore eyes we will use the same methods however, unlike the shape' fixing we first restore eye' edges Layer like we did a moment 
Select Smudge Tool in the toolbox

Choose small brush size , set the Blending mode: Normal , the tool's strength 70%
Drag on the image to restore eye' edges.

Next we will fix eye' shape by using Stamp Clone , Burn tool and Dust & Scratches filter

Step 2: Replacing details from another image

As you can see the eye' shape and edges are restored. This is probably the best result that can be obtained using photoshop' tools but the quality is still unacceptable

To improve the image quality we will replace details from another image.

In practical, there are many factors can affect the choice of images for replacement . However, when you restore the eye the main selection criteria are shooting angle and gaze direction

Open source image , Select the Lasso tool in the tool box ,select the eye and smooth selection edge.

Copy Layer (Ctrl +J) and drag it to original image. Reduce the layer's opacityand then:

• careful align , transform, scales, rotates, skews, stretches and warps eye' layer ;
• adjust layer color and tone with Curves ;
• restore appropriate shadows with Selection tool and Curves.

All the following steps are similar to the previous one . 
We will add a "natural" sharpness using detail from other image. The task is reduced to searching, transformation, adjusting suitable image' parts

When you search and replace image keep in mind some things:

• restore the original details as soon as possible before you start to replace image' parts from other photo;
• never search the images with exact likeness to the original. It is always better to transform available images
• never use high opacity setting for replaced image

Conclusion

In the tutorial we showed you general workflow and typical methods we use for restoration Heavily Damaged Photo.

We don't consider the restoration of the hair and clothing in the tutorial. The topics require prior knowledge and goes beyond the tutorial.

We hope it will be useful.
