How does PS remove the redundant part of the background

Everyone usually takes pictures or sees some pictures, and there are always some redundant parts in the background that can be removed. The following is what I brought about about how PS can remove the redundant part of the background of the picture, hoping to make everyone gain something!

PS is a method to remove the redundant part of the picture background, and the regular particle impurities in the background are removed by PS.

Photoshop core skills

A: The method of repairing along the texture and across the boundary is very practical for eliminating the clutter on the complex background.

B: Using the selection to protect the edges can make your restoration result more detailed and perfect.

When repairing details, it is suggested to get into the habit of copying on the newly-built transparent layer instead of operating directly on the background layer. This imitation mode is convenient for moving, transforming, deleting, comparing and other operations in subsequent operations. Click with the left mouse button? Create a new layer? Button to create a blank transparent layer.

What needs special attention is that when choosing? Stamp imitation tool? After that, do you have to play it? Sample? Select all layers, otherwise the stamp cannot be operated across layers, and our plan to copy the pattern on a single transparent layer will fail.

? Stamp imitation tool? There is no technical difficulty in itself, but? A cigarette, a cover? The so-called suction is sampling, and the cover is imitation. And where to sample and copy, how to sample and copy, there are many skills. The handle of the trash can is very long, and the background contains various lines and borders, so it is easy to increase the chance of dislocation by sampling many times. Because the background pattern has certain regularity, as long as you find the right sampling and imitation, you can locate it in one go. When sampling, the size of the brush is slightly larger than the handle of the trash can. It is particularly critical that the sampling should cross the boundary and take the boundary line as the alignment reference. Choice? Stamp imitation tool? After pressing the sampling key, a preview of the sample will appear on the mouse pointer.

The next few steps are crucial. Move the mouse pointer to aim the preview at the boundary crossed by the dustbin handle. Align the seams perfectly, without half dislocation, and then press and hold the left mouse button, you can see that the boundary cut by the trash can handle has been connected.

Hold down the left mouse button and drag along the handle of the garbage hopper. Don't sway from side to side, and don't inadvertently expand the scope of imitation.

After completing the repair of the first half, continue to hold down the left mouse button. Drag down until the handle of the garbage hopper disappears and the boundaries of all partitions are connected. If there are imperfections, they can be filled in appropriately.

Let's take care of the second sundry. After observation, it is found that it is not suitable to use imitation stamps to repair here. There is a simple reason. Multiple sampling and imitation are easy to dislocate the boundary and soften the edge. So, what about here? Polygon lasso tool? Select a range in the upper box, set a larger feather radius value, and switch to the background layer.

PS steps to remove the redundant part of the picture background Figure 9? Set a large feathering value.

The reason why we switched to the background layer is that we want to copy a new local layer (layer 2) by pressing the+key. If it is on the 1 floor, this area is actually transparent. How to sample without pixels? Because of the perspective relationship between the upper part and the lower part in this example, you need to execute the+key to enter the free transformation state. In this state, press the key and move the corner of the deformation frame 4 to adapt to the shape of the lower part, and pay attention to the alignment of the boundary.

If the fusion is not perfect, you can click with the left mouse button? Add layer mask? Button to create a mask for layer 2, and erase the unnecessary parts with a soft black brush.

Then there is the most skillful operation. You can see that the corner interface of the background boundary is blocked by debris. Don't rush to repair it, first observe its grain direction. My trick is to enlarge the picture as much as possible and then use it based on a small brush? Stamp imitation tool? Keep copying and? Crawl forward? . The most taboo in this position is to be aggressive. It should be repaired vertically first, and then horizontally. The two sides slowly moved closer to the middle until they met smoothly.

So, let's introduce a very important repair method, which I call it? Constituency protection edge method? . There are often sundries near the edge, and direct copying will cause problems. For example, in this case, the pattern on the hand may be covered, resulting in a goof. So choose the handle carefully with the selection box, so that no matter how you decontaminate, you won't hurt your hand. According to the selected characteristics, only the objects in the selection can be processed, and the objects outside the selection will be protected. Used here? Polygon lasso tool? Make a careful choice along the edge of the hand. Note that it is not allowed to circle the player's department, but the sundries. When framing the selection area, it should be slightly larger than the actual area. One is convenient sampling (sampling is not allowed outside the selection), and the other is to avoid traces on the edge of the selection when copying. In addition, feathering 1 pixel or even 1 pixel is required. If you enlarge the photo, you will see the difference. Pay attention to the transition of details when retouching, otherwise the sense of sawtooth will be strong.

Ps Steps for Removing the Excess Part of the Picture Background 14? Protect the edge of your hand. Remember feathering 1 pixel.

Use? Stamp imitation tool? Imitate the direction of the hand along the lines and boundaries of the background to ensure that there is no debris left on the edge of the hand. Similarly, the trick is to approach and connect the two directions in the middle. You can see that the edge details of the hand are completely unaffected.

Ps Steps for Removing the Excess Part of the Picture Background 15? The stamp will drag in the direction of the hand.

His sundries were also repaired by the Electoral District Protection Law. According to the actual situation of the photo, the feathering value can be one or two pixels higher.

PS Steps for Removing the Excess Part of the Picture Background 16? Cover up his stuff in the same way.

Finally, you can check the situation and actual effect of the patch layer. Each layer is separately affixed with corresponding sundries. After completion, the source photos in the background layer are completely free from any damage and changes.
