Light cutout-how to shoot video cutout well

How to cut out the light from the picture using photoshop?

Remove it directly to solve this problem.

Reference below:

1. Select the image you want to edit in photoshop and load it into the window, ready for editing.

2. Find the deepening tool in the toolbar on the left side of the interface, as shown in the figure.

3. At this time, the channel setting option of the burning tool will pop up at the bottom of the menu bar. Set exposure to 25.

4. Use the left mouse button to click on the scene, which requires multiple operations until there is no lighting effect.

5. The picture below is the volume effect of the photo after removing the light. How to do a good job of video cutout

When the video is shot, do not choose white as the background cloth, because the video cutout requires the video editing software to remove the background color. There will be white on the character's face and clothes, and the highlight area is also white. Therefore, when cutting out the image, the white part of the character will also be cut out. Green background cloth can be used, but because the color difference with the face is too low and there are problems with the color temperature of the light, the background of this color is not reliable. The best thing is a blue background cloth. When shooting, the characters should not wear blue clothes and accessories, so as to achieve the best keying effect.

Because the video is being taken, do not use flash. The color temperature of the light is consistent, and the white balance of the DV is set to light 5500, or it can be set to automatic. The lighting arrangement is not much different from studio photography. It is generally flat light. You can arrange the lighting position and observe the effect before making fine adjustments. The power of 70WX4 is a bit low. If you want to have good effect, you need to increase the power of the light, so that the aperture of the camera can be adjusted to a small aperture, thereby increasing the depth of field and clarity, and the stability and focusing ability of shooting are also greatly improved. . What is the fastest and most accurate way to cut out pictures in photoshop? How to cut out pictures?

Is it difficult to cut out pictures? In fact, it is not difficult at all. As long as you have enough patience and care, you only need to master the most basic photoshop knowledge to perfectly cut out pictures. Of course, this comes with time, and we should master a simpler, faster, and more effective cutout method. Cutting out pictures, also known as the legendary "transplantation of flowers and trees", is a required course for learning photoshop, and it is also one of the most important functions of photoshop. I have been studying Photoshop cutout these days, and personally, all the cutout methods can be divided into two categories: one is to cut out the selected area; the other is to use filters to cut out the image.

Picture 1

The slightly more difficult cutout is "cutting out the hair and picking out the wedding dress". Cutting out the hair refers to picking out small objects, such as hair, etc.; picking out the wedding dress means picking out the transparent Textured objects, such as wedding dresses, glasses, etc. Okay, let’s analyze photoshop cutouts in three categories:

1. One-step cutout - the most primitive and least technical cutout method.

1. Double-click the gray area of ??the photoshop window to open two material pictures.

Figure 2

2. Move the picture to the desired background picture, and change the mode of the layer to "Screen Color".

Figure 3

3. To summarize, pictures with a black background use the "screen" mode; pictures with a white background use the "multiply" mode. Of course, if the object you want to pick out is black or white, that's a different matter.

Figure 4

4. This method does not seem to work very well for pictures with white backgrounds; so we use another easier method - the magic wand tool. The main reason why I list it here is to let you understand that there is such a method corresponding to the picture with a black background. When necessary, add or subtract a selection, and sometimes you need to invert the selection; to explain, Shift+Tool, adds a selection; Alt+Tool, subtracts a selection; Ctrl+Shift+I, inverts the selection.

5. Final rendering:

In addition to using the magic wand tool, use the lasso tool and The pen tool is also a good choice, but it’s best to use the magnetic lasso tool and pen tool, which I won’t go into details here. Another point to mention is that in the PSCS3 version, there is a "Quick Selection Tool" that is more powerful than the magic wand tool. You can add selections without any shortcut keys. If you press and hold, you can select an area like painting. It is very magical. . Of course, the option bar also has three modes: new, plus, and minus. It is very intuitive and fast to quickly select images with large color differences. If you have CS3 you can try it.

6. In addition to using tools to select directly, we can also use color ranges to select areas. Note that different color tolerance values ??will result in different selections. This principle applies to not just the color range, but all parameters with tolerances, so we should think more about it when setting the parameters.

7. Move to the new image and get the final rendering.

This one-step cutout method is only suitable for works with relatively simple image components and low image quality requirements.

Learning focus:

Creation of selections;

Expanded thinking:

Before choosing which method, you should analyze the image first Color composition, and then flexibly use various tools and menu commands to create selections to achieve twice the result with half the effort.

We often hope to get high-quality images, so we must master the master-level cutout method. Let me explain it to you in two categories.

2. Cutting out hair

Method 1: Extract + Mask

1. Open the picture that needs to be cut out, and copy the background layer into three copies;< /p>

Figure 9

2. Select copy 2, filter/extract, and set the parameters as shown in the figure. Note that the forced foreground color is set to white, and the forced foreground option must be checked;

Figure 10

3. Select copy 1;

Figure 11

4. Filter/Extract, set the parameters as shown in the figure, pay attention to the settings this time Force the foreground color to black, and check the Force Foreground option;

Figure 12

5. We can hide copy 3 and the background layer, and set the mode of copies 1 and 2 to "Filter" Color" and see the effect:

Figure 13

6. Drag in a background image and see the effect.

7. Add a mask to copy 3, and then use the brush tool to smear, making sure to choose a soft tip.

Figure 15

8. Right-click the mask thumbnail and select "Apply Layer Mask".

Method 4:

1. In the channel panel, through observation and comparison, it is found that the red channel has the strongest contrast, so make a copy using Ctrl+L and adjust the color levels. .

Picture 39

2. Use a paintbrush to paint the entire inside of the cat body white.

9. As a reminder, you can also use calculations to cut out Figure, the principle is the same.

There are many methods, so I won’t go into details one by one. Go and experience them yourself.

Learning points:

1. Extraction

2. Channel

3. Mask

4. History Brush Tool

Expand your thinking:

There are many methods, but the basic principle is the same, and they all use color contrast to adjust. In actual cutout, we can adopt a more detailed range cutout, for example, make different selection adjustments to achieve a more perfect cutout effect.
