Because in the process of enlargement and reduction, once the adjustment is determined, the pixels of the picture will change accordingly. If you want to adjust it later, it is recommended to convert the picture into a smart object at the beginning. The method is as follows:

Required tools and software: computer, Photoshop(CS3 version and above)

1, first open PhotoshopCS3 version and above);

2. Drag the picture to the Photoshop workspace;

3. Then click "Layer → Smart Object → Convert to Smart Object" above PS.

4. After the conversion is successful, a small icon will be added to the lower right corner of the layer, as shown in the following box:

5. After transforming it into an intelligent object, and then zooming in and out the picture, you will find that the image is not distorted, and you are no longer afraid that it can't be adjusted later.

Extended data:

Smart object layer is a new function in Photoshop CS3, a famous image processing software. Right-click the text name of the layer and find the option to create a "smart object layer".

After the smart object layer is enlarged and reduced, the resolution of the layer will not change (difference: after the ordinary layer is reduced, the resolution will change). Moreover, smart layers have the saying of "following", that is, when a smart layer changes, the corresponding "smart layer layer copy" will also change.

You can use smart objects to do the following:

1. Perform lossless conversion. You can scale, rotate, tilt, twist, transform or deform a layer without losing the original image data or reducing the quality, because the transformation will not affect the original data.

2. Processing vector data (such as vector pictures in Illustrator). If smart objects are not used, these data will be rasterized in Photoshop.

3. Non-destructive application of filter. You can edit the filters applied to smart objects at any time.

4. Edit the smart object and automatically update all its linked instances.

5. Apply a layer mask that is linked or unlinked from the smart object layer.

6. You can't directly perform operations (such as painting, thinning, deepening or copying) on a smart object layer unless you first convert the layer to a regular layer (which will be rasterized). To perform an operation that will change the pixel data, you can edit the contents of the smart object, copy a new layer on the smart object layer, edit a copy of the smart object, or create a new layer.

Smart filter, there is a saying of "smart filter" in the filter options. When you create a smart filter, a "smart layer" is automatically created. After the smart filter is created, a sub-option similar to "effect" will be generated under the layer, that is, close or open your eyes to "not show or show" the filter effect of the layer.

In this way, multiple effects can be superimposed repeatedly, and a single effect can be turned off or on. The method is similar to "Mixed Options".
