Why does the camera have to be cut?

What is the effect of Canon's cutting mode?

Canon's cropping mode refers to a shooting mode on Canon camera, through which the cropping frame can be displayed in the viewfinder, so as to better control the shooting content and composition mode.

Using cropping mode can help photographers master composition skills quickly and get better shooting results. When using crop mode, you can aim the border at the subject that needs to be highlighted, and fine-tune the scene in the viewfinder to achieve a more perfect composition effect.

In addition, the cropping mode can also help photographers to better grasp the aspect ratio of the picture, which is also very helpful for post-processing of photos. In the post-editing, cutting the picture to achieve a better composition effect can make the picture better.

Generally speaking, Canon's cutting mode can help photographers master composition skills better and finally get better shooting results. can

1.

If our answer is yes, we should at least ensure a good bit rate and compression method (All-i or ipb for low GOP) for the previous 4K pictures without considering the hardware such as cameras. Similarly, we should also ensure that our high-definition movies can also have a suitable bit rate and coding. If the conditions are ideal, although the resolution is reduced, the resolution will increase with the down conversion, and the noise level can also be reduced.

2.

If our answer is no, it is often because our previous 4K material was compressed very badly, resulting in a lot of information loss, or because when we finally output it as a movie, the coding and rate selection have been greatly reduced, which will only be counterproductive. At the same time, we should also consider the screen level and viewing distance of the delivery channel, which will also have a certain impact on subjective clarity. As for the pre-shooting, we don't have to directly choose to reduce the resolution or crop the format just to improve the image quality brought by over-sampling, and choose the resolution and format of the project according to the actual needs.

Still life photography, how to avoid shooting mistakes?

Shooting still life is a unique photographic experience. When shooting an inanimate object, you need enough time to conceive and create the camera settings and the theme of the photo until you find the best shooting position, which is the ideal lens.

Still life photography looks simple, but it takes a lot of creativity and practice to fuse living and inanimate objects. If you are confused about lighting and framing, you need a lot of practice. So, how can we avoid the six misunderstandings of still life photography?

Error 1- improper lighting

Rule 1: The subject must have enough light. After all, this is the theme of your photos, and using natural light usually produces excellent results.

If you shoot indoors, you need to polish the subject more creatively. One of the common mistakes is shooting under artificial light sources, such as LED and fluorescent lamp. Why? Because these light sources change the natural color temperature, the subject looks unnatural. In addition, they keep inanimate objects in their original state.

Solve the lighting problem when shooting still life.

Place the subject near a natural light source, such as an open window, and be creative when the light shines on the subject. Does the light look good when it hits the subject from the side? Or does backlighting look more attractive?

Another important problem to worry about is that natural light will shine on the object you are shooting. Avoid shooting in direct sunlight. Bright sunlight will destroy the fine details and colors of objects. As a solution, if you really need to shoot in the sun, use a light adjuster such as a soft light box (or a translucent mirror) to help create a soft effect and scatter direct light.

Error 2- Distract background attention

The next common mistake in still life is to put objects in a distracting background. To ensure that the background does not contain interference, anything that attracts the viewer's attention from the main theme to the background behind it is not desirable. For example, taking vase flowers with household furniture as the background.

Solve the background problem of distracting attention when shooting still life

Choose a monochrome wall painted with a neutral color. If there is no such wall, please cover the background with a piece of white paper to avoid distracting the main object. Another trick is that if you shoot the subject on the table, it's best to cover the table carefully with white cloth or paper and focus on the main theme as much as possible.

Error 3- Missing tripod

If you need to use a slower shutter speed, make sure you don't get a blurred image. Such as decorative indoor fountain. You may need to capture the action of pouring water when the shutter is slow. In this case, it makes sense to use a tripod, because even if the camera moves slightly, the image will be blurred.

When paired with a tripod, you can use the wireless remote control to release the shutter. Therefore, even the slightest movement of the camera will not be included. As an alternative to the remote control, a 2-second timer can be used in the camera settings.

Error #4- inappropriate object

Cutting pictures helps to capture and fix the audience's attraction to your topic. When cropping an image, make sure that the theme fills the whole screen in an attractive way. Use the trisection, adjust your movements and try different angles, and you will definitely find the perfect shot.

Mistake 5- Lack of common sense

For professional and commercial still life photography, complexity is worthwhile. After making all the adjustments and taking a few photos, try to change the scene-move the object to a slightly different position, add something to the scene to supplement the object, use different angles and light sources, and change the view again and again.

Error #6- Wrong shot selection

Still life is about creating depth and displaying objects in a way that directly interacts with the audience. How to achieve this kind of attention? Shallow depth of field is recommended.

This applies to very detailed topics, such as flowers, leaves and fruits. In this scene, you need to be close to the subject, set the camera to AV (Aperture Priority) mode, and choose the longest focal length possible. The telephoto lens is the best tool for this kind of photography, because the long focal length can compress the angle of view and make the subject stand out.

This does not mean that only telephoto lenses are suitable for still life. If you want to show the details of the subject, please shoot with a telephoto lens. On the other hand, if you need to shoot everything on the table, you can use a standard 50mm lens or a wide-angle lens.

What does the clipping plane below the camera mean in 3Dmx?

The tangent plane under the camera in max software refers to moving back and forth within the camera's field of vision, taking the vertical plane of the line of sight as the tangent plane and perpendicular to the central axis of the camera's line of sight. This movement is cutting, and the displacement of the field of view caused by the movement is the displacement of the whole plane (perpendicular to the central axis of the camera). In this way, by using the function of the cutting plane, it is only necessary to adjust the front and back distance of the line of sight within a certain visual field, without changing the width, height, angle and direction of the visual field.

When you want to adjust the depth of the line of sight, you can move the camera backwards, but this is probably because an object is blocking the camera. At this time, the clipping plane function is enabled, and the near clipping (plane) is pushed in front of the object blocking the camera, and the far clipping (plane) is pushed out of the range you want to see.

Do you know the importance of the aftercrop?

Why should we crop the photos? What are the benefits of planting? What is the principle of cutting and what problems should be paid attention to in operation?

1.

Sometimes, the shooting time is fleeting: for example, the sun just rushed out of the horizon, revealing the first ray of sunshine; For example, sitting in a speeding car, a beautiful scene worth shooting suddenly passed by the window.

There are still many "fast shots, it is good to be able to shoot them." Who cares about framing and composition? " Later cutting provided an opportunity for us to readjust the composition.

For example, you took such a photo earlier.

When I took it home, I suddenly felt that I shouldn't put the horizon in the middle of the picture, thinking, "Would it be better if I put the horizon in the lower third of the picture according to the trichotomy?"

So, you can cut it out and reconstruct a picture according to your idea and the three-point method:

In addition, who told you that the three-point composition is not good, you can also try other compositions, such as edge composition:

There are many ways of composition. You can try more according to the actual situation of the photo. Wouldn't it be beautiful if the cut photos had a thoroughly remoulding effect?

2. Change the main expression effect

Portrait, the requirements for the background are quite high. The proportion of the main body, whether the background scenery is necessary, which scenery can be cut and which scenery can be preserved better should be paid attention to.

Sometimes, it is helpful to improve the quality of the whole picture to cut out the scenes in the background that are not helpful to the main body or have a low value and affect the city appearance.

In addition, increasing the screen proportion of the subject naturally highlights the subject more powerfully.

Isn't it much better after cutting the eyesore?

Of course, the bigger the proportion, the better.

In most cases, cropping can highlight a certain part of the picture, but sometimes more environmental elements and background information are displayed in the picture, which can make the picture more scene and story-telling.

This kind of situation is common in landscape photography, environmental portrait and documentary photography. Let's look at an example of "the proportion of subjects is not as small as that of subjects".

After reading the picture above, you will only think, "What is this beautiful woman doing there?" And when you see the picture below, you will know that this is actually an environmental portrait.

Change the picture style

The style of the picture is closely related to the picture. By adjusting the frame, you may find some picture experiences that you have never tried before and produce unexpected effects.

With the continuous improvement of camera image quality, the side effects of post-cropping are getting smaller and smaller-at least not as in the low-resolution era, when the mosaic is full.

In addition to the above gameplay, there are many occasions when you need to cut the screen to a specific proportion. For example, the header of WeChat must be a screen ratio of 5:9 or 1: 1; Magazine covers must be vertical, and so on.

Late case renderings:

The specific application of the latter idea, the example effect diagram is as follows:

We can find that the photos taken by this camera are a little gray. First, we use the defogging tool to make the picture more transparent:

As you can see, the picture instantly becomes more transparent, but the shadow details of the picture are seriously lost. We increase the shadow value to show the details of the shadow part of the picture:

Then we increase the natural saturation to make the color of the picture more vivid:

Then, we create a new gradient filter, and then check the anti-transfer, focusing its influence on the lower part of the screen:

We found that the proportion of water surface in the picture was a little too large. Let's cut it:

The final effect is as shown in the figure:

Finally, in the later stage of photography, there are many very important late thoughts, which guide our later steps and make our later works full of order. Today, I will introduce some of the most commonly used late thoughts to you, hoping to help you in the later process.
