Photography plus ps

Texture, transparency and cleanliness are what we pursue in the later stage of the photo, and they are also bad effects. This tutorial uses five methods to tell how to make photos more textured. Which one is suitable for your photo can be used. With the improvement of PS technology, the aesthetics will also improve. Let's have a look.

First of all, let's take a look at Baidu Encyclopedia's definition of texture: sensory judgment of objects through their surface presentation, materials and geometric dimensions.

To put it bluntly, giving an object a sense of texture is to make the contrast between light and shade of the object strong, and to show the three-dimensional characteristics of the object in a plane photo.

Method 1: Improve the overall contrast of photos.

Advantages: fast and simple.

Disadvantages: unable to adjust greatly.

When it comes to strong contrast between light and dark, many people will first think of improving contrast, and advanced people will think of S curve ▼

Essentially, S-curve and improving contrast are the same kind of methods. S-curve has stronger control over photos and can adjust more contents. But the most obvious feeling of this method is that it can't be adjusted greatly, otherwise the picture will become "dirty".

More professional explanation: the information recorded by the camera sensor is not so "uniform". Even if it is exactly the same content, there may be subtle differences in each pixel during photoelectric conversion, which is called "noise". These noises may not be obvious at low contrast, but the operation of improving the contrast makes the original subtle difference bigger, so the original pure picture will become "dirty" after greatly improving the contrast.

Take chestnuts for example. The original information of the three pixels is 100, 105 and 103 respectively. In the original film, this difference is not easy to detect. But after the contrast is greatly improved, the information of these three pixels becomes 90, 130, 100, which is obvious.

The higher-end method must be to combine the mask and adjust the area in the control film.

Method 2: Hyperbola

Advantages: almost no loss of image quality, accurate adjustment, not easy to fade when treated with neutral gray.

Disadvantages: Time-consuming, and it is more troublesome to switch layers back and forth (compared with neutral gray)

I have to mention the curve here. The most common method is to use curve adjustment layer+mask (selection). This method, in commercial photography, has a higher name, which is the famous universal dermabrasion per second: hyperbola ▼

Math teacher: Sorry, wrong set.

This is a hyperbola in later photography ▼

Create two new curve layers and pull the curves up and down respectively. The two layers are named "light" and "dark" respectively (generally called deepening and brightening in the later period of portrait) ▼

Then click on the mask part of the layer, and the shortcut key? Ctrl/Command+I inverts the layer. (Windows and Mac have different shortcut key operations, which are explained separately. Because shortcut keys are often used, the menu location is not explained in detail. After this step, you can see that the mask color of the two curve layers turns black.

Then, enlarge the photo, select the brush tool and smear the building facade. When daubing, if it is a horizontal or vertical facade, first adjust the brush size to be consistent with the internal size of the building. (Use the shortcut keys [and] to quickly set the brush size. When daubing, hold down the Shift key at the same time to ensure that the drawn lines are vertical or horizontal.

Note that the opacity of the brush should be set lower (reference value 10%), so that the operation will not be abrupt. For buildings, it is necessary to maintain the continuity of light and shadow, so the flow rate should be kept at 100%, otherwise repeated smearing may cause uneven conditions. Opacity can be set according to the actual situation of photos ▼

For some complex building facades, such as some landmark buildings with characteristics (World Financial Center: blame me for bending), it is necessary to dig out the facades separately and then smear them. There are many methods of matting, which will be mentioned later in the tutorial due to the limitation of space.

In addition to matting, there is also a channel method, which can select the highlighted places separately. Press and hold Ctrl/Command to click the RGB channel (or press Ctrl+Alt+2/Command+Option+2 to select the highlight of the photo). Compared with the matting method, the channel method is of course much faster, but at the same time, the accuracy is also reduced ▼

For hyperbola, this method is not limited to two curves. The core idea is to use several curves to adjust the tone of photos.

Method 3: Neutral ash

Advantages: almost no loss of image quality, accurate adjustment, no need to switch layers back and forth, suitable for full screen.

Disadvantages: It takes time, and it is easy to fade when treating skin (relative hyperbola).

Since hyperbola is mentioned, neutral gray is essential. The neutral ash treatment method is similar to hyperbola. However, the brightening and darkening of neutral ash are all done in one layer. Personally, I prefer neutral gray.

First create a new layer, choose soft light as the blending mode, and check "Fill 50% gray" ▼

The principle of soft light layer is: 50% gray does not affect the lower layer, which is darker than 50% gray and brighter than 50% gray.

Use a black or white brush to smear on the soft light layer to get the effect of brightening or darkening ▼

The specific daubing method is the same as hyperbola. The shortcut key D can set the color to black and white, and the shortcut key X can switch the foreground and background colors back and forth. Combining shortcut keys can greatly improve the efficiency of patch repair. For hyperbola and neutral gray, you can refer to some online neutral gray stripping tutorials. Hyperbolic and neutral gray, collectively referred to as D &；; B (thinning and deepening) is one of the most commonly used techniques in commercial retouching.

Method 4: Surrounding exposure

Advantages: no loss of image quality at all.

Disadvantages: unable to adjust moving objects, time-consuming operation.

In addition to HDR, bracketing exposure can also be used to improve the texture completely without loss. Although the hyperbola and neutral gray in the above method are good, they also change the pixels of the photo, and the surrounding exposure will not change the pixels of the picture at all.

Generally speaking, 3-5 photos with different parameters will be taken at a fixed location and opened as layers in Photoshop. 0EV is a photo under normal photometry,+1EV is an overexposed photo, and-1EV is an underexposed photo. Create a mask as shown in the figure ▼

Paint it on+1EV layer mask to brighten it. Similarly, smear it on-1EV layer mask to darken it. The specific daubing method is consistent with the hyperbolic method and neutral gray method mentioned above. The method of surround exposure can only be used for static objects, but it is not so good for moving objects.

Method 5: Other post-retouching software

Advantages: fast and simple, with remarkable effect; batch processing

Disadvantages: You need to authorize the original version to use it.

This is neither an advantage nor a disadvantage: it will bring soft light to the photo.

In addition to the above manual methods, there are automatic processing methods. Here is a post portrait software: Kebe retouching.

Kebe retouching is a professional tool and productivity tool for rapid batch processing in the later stage of photography, which is suitable for commercial portrait photography. Through batch operation, the efficiency can be improved, the operation can be simplified and the retouching time can be reduced.

Using skin texture operation can obviously improve the texture of the picture. Because it is a one-click flicker, there are not many points that can be explained. Just watch the video operation demonstration below.
