Is this photo or montage?

Inaccuracy

While doing the editing, a person uses certain tools that do not do everything you want, but what they do. It is necessary to adapt to a limited number of tools, something is most likely and will not work out as it should. You can see the joint.

Stamp Tool

This tool removes hard-to-remove fragments of the picture. He does this by copying the other photos. So it turns out quite harmoniously and unobtrusively. We are looking for similar fragments photo.

Overhauled

Once changing the tone, color, background, you can overdo it and it will look unnatural.

Unsuccessful components

Not always the pictures fit together perfectly. Not an infinite base for a man to choose from. Something may not be suitable, there is disharmony, or the person looks somehow not natural.
Either fragments of different levels of quality, the fragment may be overcompressed and not as clear as the rest of the picture.

Fragments of the old picture

Installation is made of several pictures, traces of which can be seen. Or there were unharvested fragments.

Shadows

Sourse of big light is located in one place and can not shadow on one fragment to fall to the left, and on the other - to the right. Or on one subject a sharp shadow, and another without a shadow.
This is only possible with the installation.
