To combine three photographs into a single image, you can optimally do this in Adobe Photoshop. A fairly user-friendly interface of the application will not create a dead end for you in the process of combining three different images.
Necessary
Computer, photoshop, photos
Instructions
Step 1
Loading images into Adobe Photoshop. To open three photos in the program, you need to do the following. Select the desired images in the folder, then right-click on any of the photos. Next, you need to set the command "Open with". In the window that appears, you need to select the Adobe Photoshop program by clicking on the "Select program" link. You can also open three photos through the interface of the running application. This can be done by executing the command "File" - "Open".
Step 2
After all three photos are loaded into the working area of the application, you need to set them to the same height, or the same width (depending on how the photos will be arranged in a single image). To do this, one by one resize each photo using the command "Image" - "Size". When changing the size of the image, make sure that the box "Maintain aspect ratio" is checked. After you resize the photo to the desired size, you need to create a single background to combine them later.
Step 3
Open the File menu and click the New button. Create a new document with 5000x5000 aspect ratio (this is definitely enough for you). One by one drag each of the photos onto the created background, then merge all visible layers (right column of the program) by clicking on one of them with the right mouse button.
Step 4
Select the Selection tool and select three photos against the background. Press the keyboard shortcut Ctrl + X. Go to the File menu and create a new document. When creating a document, do not change the proportions (the program will adjust the required dimensions based on the proportions of the cropped image). After creating a new background, click on it. Press the keyboard shortcut Ctrl + V. The photos will be inserted into the form. Save the image in JPEG format. Thus, you can combine three photos in one.
