is the basic step of using Photoshop to select the image and make modifications. Hopefully it will help you!
ps how to change the image pixels resolution size?
change the image pixels resolution size in Photoshop, can be achieved by adjusting the image size or resolution parameters, is the following specific steps: PH 7 method one: by
“Image size” adjust the resolution
open the image
start Photoshop, click the menu bar file → open, select the target image.

pixels size: can be synchronized width/height (units for pixels), select constraint ratio to keep the width ratio unchanged.
reset image pixels: select the plug mode (such as “two cubes” for magnification of the image).

Method 2: Adjust the plate size by using the Cutting ToolSelect Cutting Tool

The resolution (such as 300 dpi) affects print quality and the size of the pixel determines the size of the screen. When the resolution is modified, the physical size will change but the total number of pixels will not change if the resolution is not selected, the physical size will change but the total number of pixels will not change. insert method : Selecting "two cubes" when magnifying the image reduces the tear, but excessive magnification can lead to picture quality loss. file format : when saving, JPEG is suitable for photos (there are
Loss compression), PNG supports transparent background (no loss). summary steps open the image (file→open). adjust the resolution or pixel size (image→ image size or cutting tool). save the file (stored for selected format and location).
With the above method, you can flexibly control the resolution and pixel size of the image to adapt to different use scenarios (such as web display or high-quality printing).
PS how to modify the image placed
using PS to modify the image to specified size, you can follow the following steps:
It automatically adjusts proportionally. For example, shrink the original image (3264 x 2448 pixels) to 1/2, enter the width of 1632 pixels, and automatically change the height to 1224 pixels. Click “Determinate” to complete the adjustment and view the adjusted pixel information through the property panel.
II, adjust the proportionally to the specified size
, then open the image by < image> < image size> or shortcut Ctrl+Alt+I Open the settings window. cancel the selection of "restricted ratio", enter the target size directly in the pixel size bar (such as width 900 pixel, height 900 pixel). after clicking on "establish", the image will be compulsorily adjusted to the specified size, but may cause content deformation (such as the original image 3264 × 2448 pixel adjusted to 900 × 900 pixel, the shape of the grapefruit will stretch).
3.
ng>: Forced magnification can cause image quality to be blurred, it is recommended to use only when necessary. disproportionate modification key operation: the "restricted ratio" selection must be cancelled, otherwise it is not possible to freely enter the width of the high value. content protection: both methods do not delete or modify the image content, only adjust the display size.
After placing the image in the PS, you can modify the image by the following two methods:
0
Layer
As a result, the graphic layer is not editable for vector layers.
Method 2: Add the graphic layer
in the same way, after placing the image in the PS, first hold the Ctrl key, click the image layer, select the image area in the document. Then click the third button in the graphic layer panel, that is, the "Add the graphic layer" button. At this time, the image layer will add a graphic layer. After selecting the graphic version, use the rubber rubber tool to apply the image. The area of the painting in the graphic layer will become black, that is, the part of the image will be covered.Advantages: This method has greater flexibility to modify images. If you need to restore the lost parts later, simply select the mounted version and use a white pen to repaint the black area.
summarized, select the appropriate modification method according to the specific needs. If you need to permanently delete some of the image content, you can choose the grading layer; if you need to retain the flexibility of the modification in order to subsequently change or restore, you can choose to add the grading layer.
