Simple and beautiful postcards, paintings and other art objects can be created using a simple technique by combining several separate images on one field. Do you know how to combine two photos using popular image editors?
From two to one: collage technique

In Photoshop or any editor that allows you to create collages, create a new file. Add both photos one by one and arrange them in the desired way relative to each other. Frames can touch edges closely, or there can be a distance between them. You can also add a colored background. An interesting effect can be achieved by blurring the edges with the tool of the same name or by adding a decorative frame. You can create similar art in many online editors, this is convenient if there are no suitable programs on your computer.
You can connect two photos in another way. The smooth transition from one image to another looks very interesting. To begin with, we copy both images onto one base, compare their size and overlay the images on top of each other with the required gap. Now the most interesting part of the work, on the last layer we make a mask. We apply a black-and-white gradient on the mask, it may not be possible for you to achieve a beautiful blend the first time, in this case, do not be too lazy to do it all over again. Before we merge the photos into one picture and send it to print, we merge the visible layers and add some noise. Our picture is almost ready, if you wish, you can desaturate the image and choose a new color for it.
How to take a photo that wasn't there?

It is often difficult to choose from a series of photographs even a single one that fully met the expectations of the photographer and models. Most often this applies to group photos. Is it possible to merge two photos into one? For intermediate Photoshop users, this is a simple task. Suppose we are not satisfied with one of the figures in the picture or its elements. But the same figure is in a suitable form in another picture. Select the elements we need and copy them to a new layer on a good photo. Then we transfer to the required frame. The hardest part is matching the sizes. We need a free transform tool, hold down the shift key to maintain proportions. At the time of sizing, you can make the working layer translucent. When the elements are laid out appropriately, it's time to work on the borders. In order to imperceptibly connect two photos, you can use a blur and a stamp, remove unnecessary details from the top layer with an eraser.

The task is greatly simplified if we need to process the landscape. For example,add sky from one image to another similar one. We do it in the same technique, it is much easier to select and insert homogeneous large areas than to move small elements. If you are going to join two photos, be sure to pre-process both of them to the desired look, this will make the job much easier. At the very end of the combination, you can slightly adjust the colors and contrast settings.
