8 tips for simple rough handling of pictures

Every time I took a photo and checked it on a computer, I found that many photos had problems, such as poor composition, underexposure or overexposure, and blurred images. It is a pity to delete these photos, but there is no time for fine adjustments. What should I do? The following wolf introduced to you a few simple and crude methods that worked well when dealing with a large number of photos.

First and second composition, cut a good photo

Many people take pictures and press the shutter faster than the brain thinks. Many photographs do not notice the problem of composition. Fortunately, digital cameras now have larger pixels, and we can easily make a second composition by cutting.

Using the cropping tool in Photoshop, the cropping box that was pulled out is a nine-square grid, which serves as a reference for our cropping. Jiugongge composition form: divide the picture into nine equal parts of the “well” shape. When cropping, put the theme scene or character that expresses the theme of the work on the intersection of nine equal parts. The sky and the ground are best located in the upper and lower 1/3. position.

After using the cropping tool, there are 8 control points around the crop box. With this, we can pull the box wider, increase it, reduce it, and enlarge it. If you place the mouse near the corner of the crop box, you can see that the mouse turns into a double-headed arrow with a corner. At this point we can rotate the crop box by an angle. According to the composition principle of the dichotomy, after the cutting area is drawn, the second frame cutting can be realized by double-clicking the mouse in the middle of the cropping frame.

Second, gray sky blue, direct color

Sometimes, it's clear that the weather is good, but it's not blue. Shooting a film in the sun is even more pale. If you want to use lightroom or Cameraraw in terms of how to adjust, it is a long speech. It's better to come up with a crude method of direct coloring. Although the drug is very fierce, the effect is to control it.

Open the picture you want to adjust and add a new layer in the Layers panel. Then use the line selection tool box to select the part of the sky, fill it with blue, and then set the layer mode to "Multiply" in the Layers panel, according to the "Multiply" principle: when any color overlaps black, Black is produced, and the color remains the same when any color and white overlap. If you fill the sky with the ground part of the light-colored, fill with a blue to white gradient fill.

If you feel that the sky is dark, you can use the opacity setting in the Layers panel to reduce the transparency to 50% or less, and finally use "Hue/Saturation" (Menu: Image → Adjust → Hue/Saturation). The overall color adjustment changes the sky. If there is water in the screen, you should also pay attention to the uniform color of the water surface.

Third, chaotic color temperature, a fresh

Even if the current high-end SLR, in the complex light environment will be misjudgment, usually we encounter the most shooting night scene, a variety of different light color temperature mixed, cast color will be very serious.

Left: The indoor red and yellow lights are staggered, the red light dominates, and the photos are generally reddish Right: After using "Auto Color" in Photoshop

Method: Use Photoshop in the "image → adjust → automatic color" can easily change, this feature will change the white balance of the screen in accordance with the relationship between the black and white, correct the accuracy of up to 80%. The rest is then adjusted using the curve adjustment tool, such as changing the contrast and the light and shade relationship. This adjustment method is useful in most cases. However, there is a light source that can kill all digital cameras and is almost incapable of saving. It is a yellow light source.

Under the yellow light source, the digital camera basically loses the white balance correction function, and this light source is not saved in the later period. So try to stay away from such light sources when taking pictures.

Provide a very useful photo filter in Photoshop, menu: "Image → Adjustment → Photo Filter". In the color selection of the filter, we can choose the opposite cold yellow color, or use the opposite filter to try. Although it does not completely change the white balance effect of the screen, it can make the glare yellow well controlled.

Fourth, black and white high contrast, easy to change HDR

In the contrasting environment of light, the contrast between the brightness and darkness of the picture is sharp. For the sake of conservatism, smart photographers usually meter light, medium, and dark parts respectively, take one shot each, and then compose a perfectly exposed HDR shot. When too much trouble, how to solve it later?

Choosing mid-tone metering is a balanced choice in contrasting lighting environments.

In the menu: "Image → Adjustments → Shadows / Highlights". According to the change of the screen, adjust the sliders on the shadows and highlights at the same time, and observe the changes of the photos until they are satisfied. Does it feel a bit like HDR photo now?

Fifth, exposure error, histogram to save emergency

In the shooting, we have many reasons to cause the exposure of the shooting screen to be wrong. The photographs taken are not too bright, too dark, or too gray. For this type of photo, all curve adjustment tools are used. It is recommended to use Photoshop CS3.0 or later versions. There is a histogram display in the adjustment window. For the understanding and understanding of the histogram please refer to the relevant information. It is very necessary to study it.

The histogram overflows to the left and is too dark. Move the adjustment point in the lower left corner upwards. The adjustment point in it is also adjusted upwards to observe the color change of the screen until it is satisfied.

The histogram overflows to the right, too bright and overexposed. Move the adjustment point in the upper right corner downward, and adjust the adjustment point downwards. Observe the color change of the screen until you are satisfied.

There is a pixel display on both sides of the histogram. Both the dark part and the bright part are not missing. Move the adjustment points on both sides to the center. The adjustment point in the middle is adjusted according to the color of the screen until it is satisfied.

Sixth, refuse meat, clear and then clear points

The photographs are not clear enough. Apart from being related to our shooting techniques, they are also very much related to the cameras and lenses we use. For example, photographs taken on a dog's head are very "flesh" (soft for photos, not sharp enough). Also do not pay attention to using the imaging best aperture (between F5.6 and F13). For those "meat slices" we still make it sharper and look more comfortable.

The original film on the left seems very clear, but when it is zoomed in to 100%, it is uncomfortable and the picture is too soft. This is obviously a piece of meat and it feels soft. Use Photoshop's sharpening filter: "Filter →USM Sharpening". For sharpened "quantity", "radius" and other values ​​to be set according to the size and actual needs of the photo, it is not possible to use fixed parameters mechanically. Such sharpening can make "immediate changes" to those slight blurring and the reasons for the lens.

Seven, sharpen, don't use addiction

When the photos are sharpened, they need to be handled carefully, sharpened sharply, and the photos are clearly visible. They look very comfortable. After sharpening, the photo will be distorted, giving a dry feeling and looking uncomfortable. So you like sharpening, but don't be addicted.

Let's take a look at some of the sharpening tools in Photoshop. Open a photo in Photoshop, and then click on the menu: "Filter → Sharpen". We can see about 5 kinds of sharpening tools. The following wolf chooses 4 of them to represent their characteristics.

USM Sharpening: This is the old Wolf's favorite sharpening tool. From the previous Photoshop 6.0, it has always been this feature, the main advantage is that it is easy to control, and the sharpening effect is natural. When using, do not over-drag the number of sliders that are sharpened. Excessive glow will appear.

Further sharpening: This is a relatively lazy mode of operation, it is easy to appear excessive sharpening turbulence, the old wolves do not use, unless it is to do some production, you need a strong contrast effect, such as outdoor posters.

Edge Sharpening: This is also a relatively easy to use sharpening tool, it is mainly to improve the contrast of the edge, can make the outline of the photo clearer, the old wolf generally use it to sharpen some of the contours of the photo. However, sometimes over-sharpening occurs, so use it with caution.

Smart Sharpening: This is another weapon with lethality that began to appear in Photoshop CS2. It contains three sharpening methods: Gaussian mode, lens blur, and dynamic mode. Among them, the sharpest effect of "lens blurry" is best, and the other two are easily distorted, which is comparable to USM sharpening.

Eight, sharpen, distinguish between primary and secondary

When the photo is sharpened, the best way is to sharpen the key objects of the photo, such as the following macro works. When sharpening, we only make localized sharpening of insects and flower buds, so that the main subject clearer.

The method of local sharpening is very simple, you can first copy the original photo in the layers panel layer, and then click the mask settings in the layers panel, then set the foreground color in the tool palette to black, use the brush tool, set A suitable size for the pen effect, and then apply it to areas that do not require sharpening. The smeared area retains its original effect, and the area that has not been smeared is the sharpened effect.
