PS CS3 Secret: Use Photomerge to stitch pictures – photo synthesis

PS CS3 Secret: Use Photomerge to stitch pictures

When you see the magnificent scenery shown in wide panoramic photos, do you also feel envious and have an urge to imitate? However, for most people, they are unable to take a photo that expresses all the scenery due to lack of professional equipment. At this time, we use Adobe Photoshop to merge the pictures.

In fact, the picture merging in Photoshop CS2 is already very good, but for pictures with large differences or large color differences, the effect of Photoshop CS2 is still not perfect. However, with the release of Photoshop CS3, all this has been solved. Its new New Photomerge function has made huge improvements to the previous “picture merging”. The original two or three hours of work was reduced to 5 minutes, and the tones were even. ation is also well addressed.

Note: Since Photoshop CS3 does not yet have a Chinese version, the screenshots used in this article are all Chinese versions

First let us take a look at the effect of CS2

Picture merging in Photoshop CS2

In order to illustrate the difference, I chose a set of pictures that cannot be automatically assembled in CS2 and need to be manually assembled

It can be seen that despite manual adjustment, the effect is still unsatisfactory. After the picture is enlarged, the seams are obvious and the color deviation is also obvious. When I used CS2 to process this image, it took me two or three hours. I used stamps to slowly modify it and slowly equalize its tone.

Look at the effect of CS3 again.

This was made in 5 minutes using the New Photomerge function, and the effect is much better than the picture above.

First open the pictures that need to be merged in CS3

Open picture

Click “File → Automatic → photomerge options” in the menu

Start Photomerge

Click: add open files to automatically add the group of pictures that need to be combined just opened in CS3 to photomerge

Add picture

add open files will add all the JPG pictures you open in PS CS3. If there are unnecessary pictures, you can use the Remove button.

Remove picture

As shown in the picture, select the unnecessary pictures and click Remove to remove them.

We can see the row of options on the left side of the layout. What are they used for?

The options in the left row of photomerge are the stitching effect options. Select different options to create different stitching effects

Flat options

1.Auto (automatic adjustment, usually the default is this option, to create a perspective patchwork)

2.Perspective (perspective effect, basically the same as the first item)

3.Cylindrial (cylindrical effect, you can create a patchwork with good patching density and effect, this option is generally selected for patching)

4.Reposition only (only repositioning, mask modification effect)

5.Interactive layout (interactive layer, this is equivalent to free dragging and aligning in CS)

Let’s take a look at the comparison of the stitching effects made by clicking the 2.4.5 option respectively:

2 , 4, 5 stitching effects Then select Cylindrial, click OK, CS3 will automatically stitch together a perfect panorama.

It can be seen that the color tone is very even.

Partial enlargement comparison

1. It is a partial image stitched together using The new Photomerge of CS3

2. Pictures assembled using PS

We can clearly see the difference between the two
After the stitching is completed, you can use shift ctrl alt E to stamp the layer. Of course, you can also merge all the layers directly, but we have to develop the habit of trying to keep the layers when the picture is unfinished, otherwise it will be very troublesome when you find that you need to adjust it.

If you are not satisfied with the blended colors, you can also click “Edit → Auto-Blend Layers” in the menu to have the colors automatically adjust.

At this time, I am probably satisfied with the color, but I find that there are a lot of blank spaces left when the pictures are combined.

If these blank spaces are cropped directly, too much of the image will be discarded, and the composition will become very bad.

Don’t worry, let’s take your time to perfect the picture.

Click on the layer you just stamped, and click “Edit → Free Transform → Transform” in the menu.

Carefully pull the combined picture around, trying to cover the empty space. Remember to pay attention to the changes in the picture when pulling it out, and don’t pull out a distorted picture.

At this time, we can see the transformed image. Most of the blank parts have been covered, and the effect of the image has been roughly achieved, but there are still small parts of the edges. Blank, at this time we can use the cropping tool to crop it out, or we can create a border effect according to personal needs.

Of course, you can also use stamps, repair brushes, etc. to repair.

The final stage is to combine the layers.
