The higher the version, the more powerful the function

The higher the version, the higher the computer requirements.

The images processed by PS are called bitmaps, which have very rich color values. They are also called pixel images and bitmap images. Pixels are square, and each pixel has one and only one color.

Above we call it the menu bar

On the left, the toolbar, the arrows we call single and double strands. There is a solid in the lower right corner of each tool that can be clicked with the right mouse button. We use the hidden extended function.

On the right side, there is the layer panel. The position of the layer panel can be moved and adjusted. It can be pulled out and put back. If it is closed accidentally, just find the tool you want in the window.

You can change the shortcut keys. If you want to change, you can change it by holding down the ctrl English letter. After the change, click accept. If you don’t want to change, just click restore.

Perform layer visibility, turn on the little eyes to see, turn off the little eyes to hide.

The difference between pixels, centimeters and millimeters is that pixels are generally used as units when making Internet products, such as advertising banners on the web, corporate website design, personal website design, promotion website design, event website design, product brand pages of e-commerce websites , detail pages, etc., mobile icon design, UI interactive page design, and marketing illustration design for social media (Weibo, WeChat official account), etc.

The storage format of the software mode is the source file format of PS. It is a file format that can be edited twice and is reserved by the designer.

Advantages: Layer information can be retained in the layer panel, and files that have been edited can be edited again and new effects added.

Disadvantages: Large file storage, taking up more computer space

File preview format, existing in image form

Advantages: Quick preview of effects, smaller storage files, saving computer space, and convenient transmission and sharing

Disadvantages: Layer relationships are not retained, making it difficult to edit and modify again.

Linear gradient: The position where the mouse is dropped is the color value on the left, and the position where the mouse is released is the color on the right.

Radial gradient: With the mouse point as the center, the color value of the mouse point is the color value on the left, and the color value of the mouse release point is the color value on the right. It is a circular expression.

Angle gradient: gradient value changes in a clockwise manner

Symmetrical gradient: The expression is drawn from the center outwards. It is a mirror expression.

The upper two sliders cannot control transparency, while the lower two sliders adjust color. You can add color sliders multiple times. To delete, just hold down the color mark and don't let go. You can delete it by dragging it directly, or you can select the color mark stand-alone and click the delete button below.

The color slider can be double-clicked to change the color, and the opacity can only be changed stand-alone.

While the curve is brightened, the saturation is retained better, and then the contrast will be improved.

During the process of brightening, the saturation will decrease and the contrast will also decrease.

Three straws. Black point, gray point, white point, black is to darken, white is to brighten the entire picture, and gray is to focus on the whole. (Mainly aimed at adjusting the brightness of the picture)

When selecting a certain color channel, pulling it up is equivalent to increasing its brightness. Pulling it down is equivalent to adding its complementary color

Increase/decrease color vividness

If you are in full image mode and reduce the saturation to -100, the image will become black and white.

How to increase or decrease color

If you lower the brightness, the saturation of the color will decrease.

If you increase the brightness, the saturation of the color will also decrease.

Whether you increase or decrease the brightness, it will affect the saturation

The middle one represents a relatively large degree of change.

The farther away the two intervals are on both sides, the weaker the degree of change.

After checking Colorize, the picture will become a monochrome photo.

Complementary color expressions

For the brightness of the screen

One is black and white shading adjustment, which can adjust shading for color.

One is color light and dark adjustment. Change the blending mode to lightness.

Natural saturation controls a small degree of vividness, and saturation controls a large degree of vividness. Natural saturation further brightens some tonal values ​​that are not very bright, and there is basically no change in areas that are balanced at the first level.

Comes with a mask so you can paint areas you don’t want to adjust at any time

You can also double-click the thumbnail of the adjustment layer to bring up the panel and restore the parameters.

The layer below the blending layer that is to be blended with the blending layer is called the base color layer.

The layer whose blending mode changes is called a blending layer

The effect after blending mode occurs

That is, the upper and lower layers are blended exactly the same.

Reduce the opacity of the layer to create a blending effect

On the basis of this layer, reduce the opacity and randomly lose the particle value. The lost part will expose the layer below.

Comparing two layers, the brighter pixels in the current layer are replaced by the darker pixels in the underlying layer, and the pixels whose brightness value is lower than the underlying pixels remain unchanged.

Multiplying the base color and the blend color and then dividing by 255 gives you the color value of the result color, which is always darker than the original color.

After multiplication and blending, it becomes softer.

The darker the color, the stronger the contrast.

Compares the sum of all channel values ​​of two layers and displays the color with the smaller value

Lighten, remove black and leave white, which is the opposite of darkening. Compare the base color and the mixed color. Whichever value is larger will be selected as the result value.

Light colors appear and dark colors do not, resulting in a brighter image. Opposite of Multiply

A solid color and a normal photographic photo: the tint of the photo can be changed

Compares the sum of all channel values ​​of two layers and displays the color with the larger value, no third color is generated

The mid-tones change, the highlight and shadow areas remain basically the same, white is used to brighten, black is used to darken, the lightness above 50 is brightened, and the lightness below 50 is darkened

If the mixed color is lighter than the pixels of the base color, the result color will be brighter. If the mixed color is darker than the pixels of the base color, the result will be darker, which will increase the brightness contrast of the image.

If the blended color brightness is higher than 50% gray, the image will be bright, if it is lower than 50% gray, the image will be dark

Adjust contrast to darken or lighten colors

Darken or lighten colors by reducing or increasing brightness

It will replace the corresponding color according to the color value of the mixed color

Mixed Color Base Color <255 Result Color = 0

Mixed Color Base Color>=255 Result Color=255

Use the high value to reduce the value as the composite color

White is mixed with the base color to get the complementary color of the base color, black is mixed with the base color to get white

When the upper color value is greater than the lower color value, the color is 0. When the lower color value is greater = the difference between the lower color value and the upper color value, then white is mixed with the base color to get black, and black is mixed with the base color to get the base color.

When the primary color is greater than or equal to the mixed value, the mixed color is white. The primary color value is less than the mixed color, and the resulting color is more comfortable than the primary color. White and the primary color are mixed to obtain the primary color, and black and the primary color are mixed to obtain white.

After applying this filter, the entire image can appear in a motion blur state.

Pixels move toward the center from four directions, up, down, left, and right.

The pixels move from the center to the surroundings. The center expands relatively large, and the surrounding areas move away from the center and expand smaller.

Using a certain center as the center of rotation, perform twisting and rotating
