One of the strengths of PS is its ability to magically add and remove figures from within a photographic image. Check out the image pair below... the image on the left was the original.

Here is the layerv structure:

Add remove 02.png

Add

When adding one element onto another, the key philosophy is to ask the questions:

  1. What effect will the addition have on the environment?
  2. What effect will the environment have on the addition?

Compare

Here a copy of the original is placed on the top of the layer stack so it can be easily made visible and invisible. This will make it easy to refference.

Layer Groups

The addition (Revivify) and remove (Kill) are both put in layer sets for easy management.

Curves

This multiplies the figure so that its lightness values match those of the new environment.

add (Hair top)

Masking out the hair, some of the old background showed through. This was fixed by a small Cloned addition.

Man

The man figure with a simple mask.

Add (Wall)

Just a small add to get rid of an edge that looked 'wrong'. Dont know if this was really necessary.

m

This is a multiply to the man that is standing behind the addition.

m

This is a multiply onto the pillar.

add (Blur figure)

This is a hack. The man addition is a lot more blurred than the environment into which it is to be placed (below left). This was less noticeable if a copy of the figure that lies behind was given a small blur (using the Blur tool).

Remove

It is not difficult, using Cloning or cut and paste, to replicate perfectly areas of an image. The problem is managing these additions so as to produce an effective looking result. The Patch method ® is a perfect management tool for this. The patch layer 'holds' all the additions above it. The order is: Patch, Add and any number of Layer Blends as are needed to unite the result with the background. Read on...

m (Dots)

The hole pattern on the wall looks, at first glance, as if it could be easily cut and paste from the section of the wall that lies above it. However, when I tried this I found it difficult to get the edges to match. The solution was to make the pattern from scratch. The layers beneath combine to make a new section of wall. This layer is a white sold with dark grey dots on it. This was set to multiply blend mode, thus darkening the wall. It was made in the following manner:

  • A single row of dots was painted in.
  • This was selected (Command click on the layer) and duplicated / moved several times. There is a knack to this: Command Option on the selected contents and you will find that you can click and drag duplicates around at will. I dont use this much in digital painting, but it is wildly useful in making diagrams for Photoshop Wikis :)
  • A new white layer was made underneath this and the two were merged.

hue

This shifted the hue value of the addition the small amount needed in order to integrate it into the background. The hue value was sampled directly from the wall.

m

A ubiquitous Multiply layer blend. I had to paint it several times with a large brush in order to get it to work.

add (Solid plus grain)

This is a handy trick to make replacement wall, floors etc. Just fill an area with solid color (sampled from the target wall) and add some Grain. I find Clumpy grain to be the most convincing. This produced something that was quite close to the wall in texture. All such walls usually need is some local Multiply blend layer fixing and, in this case, a small hue adjust.

Wall patch

This layer is key to making the patch method work. A color, roughly approximating in value that of the background, is filled onto a new layer and a mask set to reveal only enough of that layer as is needed to conceal the figure (tip: hold down Option key whilst clicking new Layer Mask button to create a new, entirely black mask). Additions are clipped into place above this.
