+  "text": "In the real world we have different light sources which basically lights up the world around us. This can either be natural light sources like the sun, but also artificial light sources like street lamps, lamps in our houses and so on. Besides the direct light source, that is emitting light, we also have the indirect lighting. That means areas where the light is not hitting an object directly but are close to, might be brightened up as well, since the light rays are bouncing off an object and carry the light and colors of these objects into the area around it. So, but in the real world everything happens naturally, but in Blender we need to imitate these behaviors, which we can do with the help of three different things. We have different light objects, which can be used for creating artificial light sources but also the sunlight. Then we can make objects emit light using a special emission material. So each and every shape can emit light basically. And we can also make the background of our 3D scene brighten up everything. Here we can make good use of so called HDR images which basically store light data in it and then realistically light up our 3D scene. Depending on what render engine we are using and what settings we have set up and enabled, we also have the chance to use indirect lighting in our scenes which can add a lot of realism. So, but the topic lighting doesn't only include the pure fact that we light up our scene so that we can see our 3D objects. So understanding the technical use of the different light sources and settings is just one part. Because lighting is also a strong artistic tool. The way we use light and color in our scenes can have a big effect on the mood of the scene. For example, a good lighting can help us understand what time it is, what parts of the 3D scene we should focus on and really important it also can elicit emotion in the viewer. So a simple 3D scene can look warm and friendly or dark and spooky by only changing the light. So lighting is a big topic and can probably fill a full course on its own. But I do recommend if you are interested in creating good lighting study how photographers are using light to create beautiful images because in the end we are just photographers in a digital 3D environment. And here you can use the same tricks photographers and cinematographers are using to create beautiful images.",
