Ten skills of lossless PS image processing Image processing does not need too many layers. If smart objects are used, the most complex image processing can be completed at the 15 layer. The following are the commonly used image lossless editing methods of 10 that I found for you. Please refer to and read them. I hope it helps you! For more information, please pay attention to our fresh graduate training network!

1. Convert a layer into a smart object.

Smart object is the most important lossless editing method for pictures, but at present, not many users are used to using this method, which makes people feel strange. Unlike normal layers, smart objects can help you:

1. Lossless transformation.

You can zoom, rotate and distort the picture many times at will, but it will not reduce the quality of the original picture. For example, if you scale a picture to a smaller size and then want to restore it to its original size, this will not reduce the quality of the picture after using the smart object again.

2. Lossless filter.

When a filter is used on a smart object, a smart filter is generated. Smart filters allow you to edit settings at any time. In addition, in PhotoshopCS6, most filters are compatible with supporting smart objects.

3. Synchronization/link function.

If you copy a smart object, when you update the original smart object, the smart object you copied will also be updated and changed. This feature is useful when you need to copy multiple identical layers and want them to change synchronously.

How to convert a smart object: Right-click the layer and choose Convert to Smart Object.

Second, use the document & gt: the command to place pictures.

Many times, we use Photoshop to open a picture and then copy and paste it into another document. Although there is nothing wrong with this, there is actually a way to make this step faster, that is, you can use the "Place" command, which can put pictures in Photoshop and automatically convert them into smart objects, saving you a lot of time.

Using file >: placement, you can also put files in RAW, AI and other formats into documents and directly convert them into smart objects. For example, you can place a RAW file, and you can double-click the smart object at any time to edit it with AdobeCameraRAW. In this way, before the image processing, there is no need to convert the picture in RAW format into JPG format.

Third, cut and paste the mask with layers.

Many people know the layer clipping mask, but most people don't know how to use it correctly. Many times, we will use layer mask to remove redundant images, thus completing the matting. But if the edited layer is a smart object, this method will not work. At this time, there is only one way. If one layer of mask is not enough, it can be merged and added again. As shown in the figure below:

Do I need to use more than one mask? Combine all layers into a group, and then add a mask to the group.

In addition to creating layer mask, layer clipping mask is also a good matting method. If you really can't cut and paste the mask with layers, you can combine these layers into a group and then apply the mask to this group separately. In PhotoshopCS6, you can even create a layer clipping mask for a group.

Fourth, keep the picture effect simple.

At present, there are many ways to adjust the picture effect, and most of the effects can be achieved by using several adjustment layers. One layer effect can be superimposed on another layer effect, and the two layers can overlap. However, we should try to create the same picture effect with fewer layers. The premise is that you need to know the meaning of each adjustment layer, rather than trying aimlessly. This is not only complicated in process, but also poor in image quality.

Fifth, use smart filters.

One of the benefits of using smart objects is that you can apply smart filters. You can use smart filters when converting layers into smart objects. Smart filter is the most important lossless editing method in the process of filter use. In addition, the smart filter allows users to change the effect of the filter at any time without any loss.

Six. Use Brightening and Deepening on Layers

Brightening and deepening are important parts of image editing. Using this technology can help you simplify many unnecessary layers. You can also use fade and deepen directly on smart objects, but you need to use the following methods:

1. Edit new layer >; : Fill, select 50% gray level from the drop-down menu, and then click OK;

2. Change the blending mode of the layer to overlay (you can also try other blending modes, such as soft light and strong light. );

Finally, you can use the Brightening and Deepening tools on this gray layer.

Seven, nondestructive cutting

The simplest lossless editing method is lossless cutting. When using the crop tool, disable ""in the options bar. Delete crop pixels "option. Essentially, this command tells Photoshop to keep the pixels of the cropped image so that you can cut images of other forms or sizes later.

Eight. Organize layers with names, groups, and labels.

In the process of image processing, many layers often appear. Be sure to keep the layers organized, because it will save you a lot of time and make your image processing process more efficient. The methods at the organizational level vary from person to person, so choose the method that suits you best. For example, you can create groups for foreground, middle scene and background, or you can create groups by object.

Nine, keep the minimum number of layers

If you make a PSD file with a layer of 100, you may think it is something to show off, because it means that you have invested a lot of time and energy in creating works. But now it seems that this may mean that your efficiency is not high. At present, PhotoshopCS6 (or above) provides lossless editing. You don't have to use so many layers anymore. By using smart objects, smart filters, clipping masks and other methods, the lossless editing of pictures can be completed efficiently with the least number of layers.

X. End your bad habits and practice lossless editing skills.

If you are always used to sloppy and messy work, these methods are useless to you. Bad habits are easy to form, but they are not conducive to work; Good habits are hard to form, but they are very useful for work. It is one of the most difficult things for designers to change their long-standing bad habits.

The lossless editing of pictures may make many people feel unaccustomed at first, but when you actually apply it, especially after you are familiar with it, you will feel that the lossless editing technology of these pictures can greatly improve your work efficiency!

; How to accurately cut ps?

1. Open the PS file and click Image-Cut in the menu bar.

2. Click the transparent pixel in the open dialog box, and select the direction to cut in the cutting range.

10, and then you can see the graph just cut on the desktop.

The above content is how to crop pictures with PS. The reason why centimeters and pixels are not used is because PS software is troublesome to deal with centimeters and pixels, and the pixels in the picture are too large and blurred. Therefore, the maximum rectangular scale can crop the picture more perfectly.

Extended data:

Graphic design is the most widely used field of PS. Whether it is the cover of the book we are reading, or the posters and posters we see on the street, these image-rich print products basically need PS software to process the images. So it is necessary for everyone to learn the most basic cutting.
