The image size tool in PS cc is detailed

Today's article is about the use of the image size tool, PS cc for this tool has been improved and updated, let us deal with the size of the picture, we can better maintain the authenticity of the original. Let's take a look at it together.

The core of PS is the processing of images (usually bitmaps). If you are free to manipulate the bitmap you create, you will receive unexpected results.

Before you improve, if you have a small picture, you will encounter difficulties in processing the image size. You can enlarge the image (Resample), but there are only so many pixels in the image, the magnified image will make it blurred and distorted, thus reducing the quality of the picture. One way to deal with this problem is to use filter > sharpen to restore a bit of clarity to the distorted image but not to be effective.

This is the interface of the image sizing tool after PS cc improvement. Let's take a look at how it operates, select Image > Image size, and display the upgraded Image Size dialog box:

The first thing you should notice is that you can resize the dialog box to adjust the size of the Image Preview window to show more images.

This is the adjusted Image Size dialog box:

The second thing to note: You can see a few new controls on the right side of the dialog box. Changing their settings can change the resampling of the image.

There are many options after resampling, and you can access the following options after the Drop-down menu: Automatic, retaining details (enlarged), two cubic (smoother) (enlarged), two cubic (sharper) (reduced), two cubic (smooth gradient), adjacent edge (hard edge), and two times linear. You can also quickly access them through keyboard shortcuts.

This explains what they mean:

Automatic: Photoshop picks the Resample method based on the document type and whether the document is enlarged or reduced.

Retention details (Extended): Select this method to use the noise reduction slider to eliminate noise when zooming in on the image.

Two cubic (enlarged): An effective image amplification method based on two cubic interpolation and designed to produce smoother effects.

Two cubic (sharper) (reduced): An effective image reduction method based on two cubic interpolation and enhanced sharpening effect. This method retains the details in the resampling image. If you use "two cubic cubes (sharper)" to make certain areas of the image more sharp, try to use the "two cubic cube."

Two cubic cube (smooth gradient): A method of analyzing the value of surrounding pixels as a basis, the speed is slower, but the precision is high. The "Two cubic cube" uses more complex calculations, resulting in smoother tonal gradients that are smoother than "neighboring" or "two-time linear".

Proximity (hard edge): a fast but low precision image pixel simulation method. This method preserves the hard edges and generates smaller files in the artwork that contains the jagged edges. However, this method can produce jagged effects that become apparent when you distort or scale the image or perform multiple operations on a selection.

Two times linear: a method of adding pixels by averaging the color values of the surrounding pixels. This method produces a medium-quality image.

Note that if you choose to keep the details set, the slider that reduces noise will also appear. This allows you to further adjust the image quality control.

When you adjust these settings to change your image, you will find that there are always some of the resampling tools that you use most conveniently. And, since they are all accessible, you can try a lot to test all the options to find out what works for you, and the results are good, and this process takes a few minutes at most.

In the actual operation, you use the retention details and reduce noise this option will be more. So I suggest you choose a percentage instead of a pixel when choosing a unit (when you're learning), so you know how many times the image has been enlarged or shrunk. When you are familiar with the different effects of these settings, you can try switching to centimeters, inches, pixels, and so on.

Here is an example in the actual operation, the image is sampled by 300%.

After clicking OK, the software will take a few seconds to process the image. The resulting new image is the result of your adjustment.

Limitations

The updated image size tool offers more possibilities, but there are some limitations:

A. Make sure the image quality is good before operation. It's important to have good color saturation and sharp edges.

B. Darken darken shadows or magnified highlights these cannot be repaired.

C. The image must be of a certain size. If your image is just an icon (100x100 pixel), don't expect it too much because it may lack the necessary color information.

Conclusion

Before you decide to use this new image size tool, you first need to understand what you want to achieve. If your image is intended to be used in a Web page, you want to make it bigger, that's fine; if you're going to use the image to print, it's not the same. The only way you have to try more, find the most appropriate settings, if you can't just give up the picture.

You may find that PS software actually improves the original clarity and detail of the image. I used another piece of noise to test the tool, and for a few seconds, I used the slider to reduce noise to eliminate most of the noise, which worked fine.

The screen shot of the frog above is the effect that I magnified the original image by 800%. You can see a little bit of softening around the eyes, in short, the noise reduction settings are particularly impressive.

Hopefully, this will give you a better idea of the image size tool in PS cc, and I hope you like this article!
