A quick way to build a realistic scene in Blender

Creating a fully CGI scene is fun but also a time-consuming job and requires a lot of skills to make everything look realistic. From modeling or finding models, texturing, lighting, post-processing, etc. But what if we already have a photo or video that we just want to extend with some elements?
In this tutorial, we will talk about exactly that. How to extend a photo with 3D elements in a free program blender.

We'll talk about how to import an image and camera into a blender with the correct perspective.
How to set lighting, shadows, and reflection to match the photo.
How to enrich the visual boring and low-resolution textures.
Where to find and how to add overlays that will make the scene more cinematic.
We will talk about post-processing color grading and much more.

At the end of this tutorial, you will be able to extend any photo with any 3d elements and get more realistic renders in a faster way.
All resources and links are included + final .blend file
