How to remove the rules in the background

If the background to remove debris is solid color, or granular, are relatively easy. The tricky situation is that the background contains regular lines, such as a variety of patterns, borders or fur. A little careless, in the imitation process will produce dislocation and leave traces of human.

Figure 1-2 After the cleanup, there is no more clutter distracting.

　　Core Skills

A: The border-crossing repair method is useful for removing clutter from complex backgrounds.

B: With the selection of the edge of the protection, you can make your repair results more refined, more perfect.

When patching, it is recommended that you create a copy operation on a newly created transparent layer, rather than working directly on the background layer. This imitation of the pattern to facilitate the subsequent operation of Mobile, transform, delete, contrast and so on. Left-click the Create New Layer button to create a blank transparent layer.

It is important to note that when the Clone Stamp tool is selected, it is important to select "Swatch" as all layers on its options bar, or the stamp cannot operate across layers, and our plan to clone the pattern on a separate transparent layer fails.

"Imitation stamp tool" itself is not technically difficult, nothing more than "a suction cover", the so-called suction is sampling, and the lid is imitation. And where to sample where to replicate, how to sample replication, there are a lot of skills in this area. The handle of the garbage bucket is very long, and the background contains a variety of lines and borders, if multiple sampling can easily increase the probability of dislocation. Because the background of the pattern has a certain regularity, as long as the sampling and imitation location can be coherent. When sampling, the brush size is slightly larger than the handle of the garbage bucket. It is particularly critical that the sampling be across the boundary, with the border lines as the reference material. When you select the Clone Stamp tool, the mouse pointer appears with a sample preview when you press the key to sample.

The next few steps are critical. Move the mouse pointer and align the preview to the boundary across the garbage bucket handle. To fit the alignment, do not have a partial dislocation, and then hold down the left mouse button, you can see by the garbage bucket handle cut off the border has been connected to a paragraph.

Hold down the left mouse button and drag along the handle direction of the garbage bucket. Do not sway around, do not inadvertently expand the scope of imitation.

After you finish repairing the top half, continue holding down the left mouse button. Drag down until the handle of the garbage bucket disappears, all the partitions are connected, if there is an imperfect place can be properly padded.

To fix the second piece of debris. After observation, it is not appropriate to use the clone stamp to fix it. The reason is simple, multiple sampling and imitation easily make the boundary dislocation and soften the edge. Therefore, use the Polygon Lasso tool to select a range in the upper half of the box, set a larger feather radius value, and switch to the background layer.

Figure 1-9 Setting a larger feather value

The reason to switch to the background layer is because we press the + key to copy the local new layer (Layer 2) when something is desirable, if the layer 1, the area is actually transparent, no pixels and how to sample it? Because this example has a small perspective relationship, you need to perform the + key into the free transform state, press the key in that state and move the deformation box 4 Angle to fit the lower shape, note that you want to align the border.

If the fusion is not perfect, you can click the Add Layer Mask button to create a mask for Layer 2 and erase unwanted parts with a soft black brush.

Then came the most tricky operation. You can see the corner interface of the background boundary being obscured by sundries. Do not first rush to repair, first observe the direction of its grain. My trick is to enlarge the screen as much as possible, and then use the "Clone Stamp Tool" based on the small brush to constantly clone and "crawl forward." This position is the most taboo is aggressive, should be fixed to a point, and then a horizontal patch. Both sides slowly closer to the middle, until the smooth phase.

Next, we will introduce a very important patching method, I call it "constituency protection Edge method". Often there will be close to the edge of the debris appear, if the direct imitation will be problematic. In this case, for example, it is possible to put a pattern on the hand to create a dressing. So you need to put your hands in a selection box, so how to decontamination will not hurt your hand. Based on the feature of a selection, only the objects within the selection can be processed, and the outside of the selection is protected. This uses the polygonal lasso tool, which is a fine selection along the edges of the hand. Note that you are not allowed to circle the players, but the clutter. Box selection is slightly larger than the actual area of need, one is to facilitate sampling (the selection can not be sampled), and the second is to avoid imitation in the selection edge traces. In addition, it is necessary to feather 1 pixels, even 1 pixels. Zoom in on the screen will be different, repair the map to pay attention to the details of the transition, or a strong sense of sawtooth.

Figure 1-14 The edge of the protective hand remember to feather 1 pixels

Use the Clone Stamp tool to copy the direction of your hand along the texture and boundaries of the background to ensure that there is no residue on the edge of the hand. In the same way, the trick is that both sides aspire to be close and connected. The edges of the hand can be seen at all without being affected.

The sundries in their hands are also patched with the same selection of protection laws. Depending on the actual picture, the feather value can be up to one or two pixels high.

Fig. 1-16 the same method to cover the clutter of the hand

Finally, you can see the patched layer and the actual effect, each layer is a separate repair of the corresponding sundries, completed, the background layer of the source photos without any damage and change.
