In the later stage of photography, magnification and cropping is often used to make up for the composition problems during shooting, or to intercept parts from large scenes, such as when shooting birds, large cropping is likely to be used.

This time, I will explain a plug-in that enlarges the picture without damage.

I think in this picture, only cut and retain the top of the mountain in the yellow box, this is a large cut, normally it is difficult to get a clear picture.

Comparison before and after using this plug-in:

The details on the right are obviously stronger than those on the left, and you can see the texture and clear outline of the rock.

The plug-in needs to be installed additionally, and then find the plug-in in the "automatic" section of "File" on Photoshop.

Win is the Chinese version, mac is the English version, both Chinese and English.

Step 1: crop the image

First of all, select "cropping" for secondary composition.

This is the functional interface for cropping. On the right side of the interface, you can choose the clipping mode. As follows:

Mode 1: cut according to the scale of the picture, you can choose the free scale, or you can choose the scale template it gives.

Mode 2: manually set the number of pixels for length and width.

Step 2: after setting the image size, go back to the main interface of the plug-in and choose the size of the new image you want to get, that is, how many pixels you want the new image to be long and wide. As follows:

Select the resolution of the new image at the top right of the interface, and the specific value of the current resolution will be displayed at the bottom left of the interface.

There are three modes of picture resizing:

1. In proportion. To magnify the length and width by a certain multiple, here are several options "2x, 4x, 6x" or you can set them as you like, such as "1.3x, 2.2x".

2. According to the widest edge. In fact, it is manually set the value of the long side, and the short side is automatically generated according to the proportion. If you have specific pixel size requirements, you can use this.

3. According to the highest edge. In fact, it is the value of the short side set manually, and the long side is automatically generated according to the proportion.

Step 3: choose the lossless algorithm when we choose the size of the new picture, we have to start lossless processing, which is actually an intelligent algorithm.

There are 5 lossless processing algorithms:

1. Standard. The conventional general algorithm is suitable for most scenarios.

2. Lines. Suitable for dealing with architectural images, there are horizontal, horizontal and vertical line structure in the screen.

3. Art. This restoration of details is a little exaggerated and may feel a little unnatural.

4. Low resolution. This algorithm mode is suitable for the new cropped image with low resolution.

5. Very compressed. When the image compression is serious, it is suitable to use this algorithm mode.

However, some students said that he could not tell which mode to use, so the plug-in prepared a four-view preview function for everyone, at the top of the plug-in, as follows:

The four-view preview allows you to compare the effects of many different algorithms at the same time, see the differences intuitively, and choose the most comfortable one.

This is the effect of four views, the top left view is the original image without lossless processing, the other three views are loaded with algorithms, we can click on the right side of the different algorithms to load, and then compare the results, choose the best one.

Step 4: noise and details

Noise suppression: in fact, it is noise reduction, but too much noise reduction, the loss of detail will be serious.

Remove blur: in fact, it is to restore the details, but if the details are restored, the noise will be obvious.

Therefore, this is to find a balance between noise reduction and details, it is recommended that we choose "automatic", let the software calculate the balance point.

Step 5: other optimization settings

Reduce color overflow: mainly work on the dark part of the picture, so that the color of the dark part is not muddy. The effect is as follows:

Facial optimization: make the complexion of the character more smooth and natural. Available when dealing with portraits.

This is the end of the plug-in usage. This plug-in will greatly increase the possibility of our secondary composition.
