Mining in DPPs mode

1. Or what is DPPs in S? It's their code. I know it's theirs

2. PT refers to the font size (PT = point, which means point)
DP should be DPI, which means resolution

3.

try swapping the top and bottom layers

4. Multi channel mode: in multi-channel mode, the first channel stores the information of color elements in the image in 256 gray scale. This mode is mostly used for specific printing or output. When converting an image to multi-channel mode, the following principles can be used: color channel in the original image becomes spot color channel in the converted image. By converting CMYK images to multi-channel mode, you can create cyan, magenta, yellow, and black spot color channels. By converting RGB image into multi-channel mode, you can create cyan, magenta and yellow spot color channels. By deleting a channel from RGB, CMYK or lab images, the image can be automatically converted to multi-channel mode. To output multi-channel images, store them in Photoshop DCS 2.0 format, which is very useful for images with special printing requirements. For example, if only one or two or three colors are used in the image, using multi-channel color mode can rece the printing cost

5. As a matter of fact, I have already talked about your question very well
it's just that the models you mentioned are not complete< In addition to RGB color
CMYK color
lab
Color
there is gray level
index
difference: pictures adjusted to gray level are gray no matter how they are edited in the future
index: only 256 colors are supported, so pictures of GIF are in index mode, which can only be edited by converting them to RGB or other modes, otherwise many functions will never get up, But it's better to convert to RGB first.

7. Normal - in some modes, the image will appear in its original appearance or color. If it is applied on a layer, the image representing the current layer will completely cover the top of the lower image. Dissolve - this mode rearranges the pixels of the edited image or the current layer in a random manner to proce a random distribution of speckles. Lightening - when the color of the lower image is deeper than that of the current layer, it will be replaced, otherwise it will be retained. This mode is suitable for halo or reflection effect. This mode will proce a deepening effect according to the color of the current layer image and the color of the lower layer image, so the color will become darker. Color deepening - increases the pixel contrast of the drawing to show the drawing color without changing the background color when drawing in white. Linear deepening - reces the brightness of the drawing pixels to display the drawing color without changing the background color when drawing in white. Filter color - this mode is the opposite of the positive stack bottom. It proces a brightening effect according to the colors of the two, so the brightness will be increased and the color will be lighter. Color fade - the closer the color of the upper image is to white, the brighter the lower image will become, but the black part will not be affected. Generally speaking, this mode can rece the brightness of the image, which is suitable for enhancing the brightness effect. Linear fade - some modes are similar to the color deepen mode, except that the black part of the lower image is also affected. Overlay - this mode will get the effect of mixing the color of the current layer image with the color of the lower layer image, and can deepen the dark part of the image, or brighten the bright part. It is suitable for enhancing contrast and saturation. Soft light - this mode can make the color bright or dark. The specific effect depends on the mixed color. When the color of the current image is more than 50% gray, the lower image will be dark. When the color of the current layer is less than 50%, the lower image will be bright. Strong light - this mode is an enhanced version of soft light, which can also make the color darker or brighter, but the biggest difference is that the strong light mode proces pure black or pure white, while the soft light mode does not. Bright light - if the drawing color is greater than 50% gray level, it will be mixed in color deepening mode and the combined image will be dimmed. On the contrary, if the drawing color is less than 50% gray level, it will be mixed in color lightening mode to make the image brighter. Linear light - if the drawing color is greater than 50% gray, the image will be dimmed by blending in linear deepening mode; otherwise, if the drawing color is less than 50% gray, the image will be brightened by blending in linear thinning mode. Point light - if the drawing color is greater than 50% gray, the bright pixels will be replaced and the dark pixels will remain unchanged. Otherwise, if the drawing color is less than 50% gray, the dark pixels will be replaced and the variable pixels will remain unchanged. This mode can be used to add special effects to the image. Difference - this mode will adjust the color of the lower layer image according to the brightness of the color of the current layer image. If the color of the image of the current layer is white, the color of the image corresponding to the lower layer will be reversed. If the color of the image of the current layer is black, the color of the image corresponding to the lower layer will not change at all. For the color between white and black, different degrees of reverse processing will be carried out according to the corresponding color. The result of this mixed mode is the most difficult to predict, so it often has amazing effects. This mode is generally used in the proction of works with strange atmosphere. Exclusion - this mode is very similar to the difference. The only difference is that this mode will turn the lower layer image corresponding to the medium brightness color of the current layer image into gray, so the effect is not as obvious as the difference, and the feeling is softer. Hue - this mode will retain the chroma of the image color of the current layer, and then mix it with the saturation and brightness of the color of the lower layer image. That is to say, the chroma of the color of the lower layer image will not change. Saturation - this mode retains the saturation of the image color of the current layer, and then mixes with the brightness of the lower image color, that is, the chromaticity variation of the lower image color will not change. Color - this mode will retain the chroma and saturation of the image color of the current layer, and then mix with the brightness of the lower image color, so the brightness of the lower image color will not change. Brightness - this mode is opposite to the color mode. It will retain the brightness of the color of the current picture, and then mix it with the chroma and saturation of the lower picture. Therefore, the chroma and saturation of the lower layer will not change

8. After you select multi-channel, the image is not in the form of RGB or CMYK channel combination, but separated channels, such as R, G and B. that's for more convenient editing channels, color matching or mask making. There's no practical significance. When it's stored, the channels will be combined

9. Image mode RGB color
or when the new canvas jumps out of the new dialog box, adjust the color mode to RGB color
