Professional Photograph Restoration Workflow
In this tutorial, we'll take an in-depth look at restoring an old
torn photograph. Restoring old family photos is something that you can
do for your relatives and bring tears to their eyes, and yes this is a
service you can offer to clients as well. Let's take a look at a
professional workflow for restoring old photographs to their former
glory.
1. Introduction
When deciding on which picture to use for this tutorial, I
encountered the lack of material I could use in public. The picture
provided is a family photo sent to me in a terrible scan resolution. But
the picture was just the kind of picture I found right for this kind of
tutorial. And the end result also shows that you actually can work on
poor scanned pictures and get reasonably good results.
The print size is of course limited due to this. That said. The
importance with this tutorial is guiding you through the workflow
process. There are some important steps, however, you must keep in mind,
but never hesitate to be creative and explore different approaches. The
steps to follow are:
- Make a copy of the original to work from
- Adjust the dimension you need and crop the image so you don't work on areas you don't need.
- Retouch/restore areas in the image as needed.
- Remove noise or unwanted patterns
- Adjust highlights shadows and neutrals (in color photos you would also adjust skin color)
- Adjust the brightness and contrast
- Sharpen
Step 1
And now for the workflow and tutorial. In Step 1 I have already
specified dimensions and cropped the image. You would then go about the
restoration. I always start out in photos like this with the patch tool
and get larger areas roughly patched. Then I get more specific and
change between the Patch Tool, the Healing Tool, and the Clone Tool as
suited. I'll explain in more detail in the next steps.
Step 2
The Patch Tool works just as the Marquee Tool in regards to behavior.
You drag a selection around the area you want to fix, then you click in
the middle of your selection, and whilst holding the mouse button down,
you drag the selection to another location in the picture with
similarities and let go. Be sure to align your selection before you let
it go. See next step and watch the alignment.
Step 3
Watch alignment in the shades of the curtain in the background. Do
all larger areas in the picture. This tool not only works great, but
it's also a timesaver and a good way to start your restoration.
Step 4
After getting all the larger areas done change to the Healing Brush
Tool (see corresponding red color in the picture below) and Clone Stamp
Tool. As you work on your picture always feel free to experiment with
these tools. If you are concerned with an efficient workflow, it's good
to get the grasp of these three tools.
Note that the Spot Healing Tool is also a tool you would use where,
as its name suggests, there are spots. It works by just clicking on the
spots you want to remove and I find myself using this often in some
pictures where there are spots scattered around in the image. The
workflow would then be to start out with the Spot Healing Brush, then
changing between this and the Healing Brush Tool. In this picture, I had
no need for it though.
As the picture below suggest, I use the Clone Stamp Tool at the edges
of the picture. The Healing Brush Tool and the Patch Tool will usually
create some effects you don't want when you work towards the edges of a
picture. Just try it out and you'll see what I mean. Again, just change
between the tools and feel free to experiment between them until you get
your desired result.
Step 5
Here we have done the first part of the restoration.
Step 6
And now for the serious defections in our picture. Here we’ll use the
man’s right eye to substitute his missing left eye. Just draw a rough
marquee selection around his right eye, and then hit Command + J to jump
the layer (copy the selection to a new layer).
Step 7
Then hit Command + T to enter the Free Transform Tool.
Step 8
Right-click inside the selection and hit Flip Horizontal.
Step 9
At this point, when you drag the selection over to where the left eye
should be, you would want to lower the Opacity and align the eye with
what's left of his torn away eye behind your new layer. When you have it
aligned, hit enter or hit the mark I've placed the green circle around
(shown below) to commit the changes. Then raise the Opacity to 100%
again.
Step 10
Now, with the layer selected hit the mask-button (as indicated by the green circle below) too apply a mask.
Step 11
Now we want to paint with black in the mask to hide the areas we
don't need or don't want to see. When using masks the rule is: white
reveals and black conceals. If you need soft transitions, use gray. A
good way to paint away areas in your selection is to lower the opacity
of your brush, then sweep across the areas you want to get rid of until
you have the transition result between the two layers you would want.
Bonus Tip: Keep your finger at the X button to flip between black and
white. It's always good to go back and forth like this in smaller areas
until you get what you want. The D key will make your foreground and
background colors black and white if the colors are set to something
different than black and white. If you want to see only the mask on your
screen to smoothen out the areas, hold down the Alt key and click the
mask.
Step 12
Now you want to do the same process with the ear. Depending on the
picture you would try out different free transform modes you also could
use. For the ear I did use warp. I also did a minor part from the
hairline at the man's right side, rotated , and scaled it slightly just
to get a better start for the missing hairline. Then I cloned where
needed.
If you look at my layers here, don't be confused. The "retouch" layer
is the next step, but when doing the picture I didn't decide on the
hairline right away. The layer called "Layer 1" is the hairline layer.
Step 13
After getting all the larger parts into place, I went back to the
Clone Tool and touched up all the edges I needed to fix. This is what I
put on its own layer; the "retouch" layer. Usually you want the Opacity
on the Clone Tool set down so you get better control over the cloning
and can do them in more than one sweep. Just drag over the area until
you get the result you desire. Command + Z is of course something you
want to keep your fingers at during the whole of this process.
Step 14
Often when you go about doing the last retouching, you would use
different layers for different parts. If you don't want a lot of layers,
just merge them down when you are satisfied. I usually do small parts
on different layers and merge them back to one "retouch" layer, but
never merge these basic layers.
You don't want to merge everything together if you later see
something you didn't spot right away. It's always good to be able to go
back and delete only the "retouch" layer, and fix that, or the
eye-layer, if you found something out of place in it, and so on.
Step 15
So now the restoration part is done.
Step 16
The next thing I do is to select all the layers and group them.
Command + G. Then I make a new layer from this group. Command + Shift +
Alt + E and rename it "noise." This layer is for our noise reduction.
One thing I want to point out, which I probably haven't mentioned.
As you can see from my layers below I've kept the original file in
the PSD as the background layer, and then turned it off. I like to keep
the original file together with my PSD file, so I always start by
jumping this (Command + J). This way I get an exact copy to work from,
then turn of the background.
Bonus Tip: If you hold the Alt key down while clicking on the eye in
front of the background image, you turn this layer on and all the other
layers off. Click again to turn this layer off, and all the others on.
Good for quick comparisons.
Step 17
Now we remove noise in the image. Noise reduction is done in various
ways, but here I use the Reduce Noise filter found under Noise. I
exaggerated the noise reduction a little for this tutorial, and believe
my original numbers were 8 for the strength and about 20 for detail.
Another tip here is to go into the Advanced Dialogue and crank the
strength up to full in the blue channel with 0 on details. In the red
channel you crank also the strength up high with some detail, and leave
the red channel with no alterations. This lets the red channel keep some
of the details in the picture without blurring it too much. This
technique I got from Taz Tally, and is what you also would want to do to
remove patterns or scan lines.
Step 18
After noise reductions we would go on to sharpening. Sharpening is
another big topic, but a common use, and a good one, is the High Pass
Sharpening. When you apply the High Pass filter, you would want to use
low settings.
For this tutorial, I have raised the values a bit too much, and you
would want to see less in the gray picture than here. The edges are what
you want to sharpen. There are also some technical issues you want to
keep in mind.
When you sharpen for print, you always want to over-sharpen a little
on screen. Printers have a natural way to blur out pictures a little.
When you have applied the High Pass filter you would set the Blending
Mode to Overlay or Soft Light. I usually make use of a little over
sharpen anyhow, and then lower the value by using the opacity control.
Bonus Tip: Often you would want to sharpen only areas of the picture.
In the example picture below, I've made a mask and painted away
everything but the face, so this is the only part that gets sharpened.
Often this technique is used for only the eyes.
The technique works also well using curves to lighten or darken areas
of the picture. If you only want the eyes lighter, you would make a
curves layer, hit Command + I to invert the mask, making the mask go
black, and paint back with white where the eyes are, and so on. It's
quicker to invert the mask than starting to paint away everything you
don't want.
Step 19
In this final step, I did adjust the contrast with an s-curve. This
step I didn't make use of in my original file, and you would probably
want to do it before the sharpening, but I added it here just to get a
more complete workflow overview, since that is the nature of this
tutorial. I often make use of Command + Shift + Alt + E to make a new
layer from the layers below, and that's what I would have done here.
I would have put the "curves" layer over the "noise" layer, then
merging all the layers below to a new layer on top. Next sharpen this
with the High Pass filter, keeping the curves layer intact, just in case
I wanted to go back and adjust the last two steps.
2. Conclusion
So this was a the whole process of restoring an old, torn photograph.
But keep in mind that a lot of these steps can be explored in greater
depth. Always experiment and look for things you could add to your
workflow to get an even better result.
