Types of Lamps in Blender
Point Is a light that goes in all directions from a single point
Sun Acts like Sunlight, with all the light travelling in the
same direction Spot
Acts like a spot light, with the spot size limiting how big it is.
Hemi Is a 180 degree constant light source.
Area Creates an area of multiple lights in an area
Basic Lighting Functions
Key light A key light is the main light of a composition. It
usually lights the main focus of the scene, by illuminating the detail of the objects.
Fill light The fill light works with the key light, lighting some
of the darker areas of the image created by the key light.
Back light The backlight or Rim light helps distinguishing the
foreground from the background. It creates a rim of light on the edges of objects,
giving them another level of dimensionality.
Lighting Rigs
1-Point light rig The simplest rig, using a single key light. It gives a high contrast between the light & shadow
2-Point light rig Consisting of a key and fill light. It is typically used for even illumination a scene or for
product lighting for a company. 3-Point light rig
The most commonly used rig can be either in a Studio or Standard rig setups The Studio rig consists of a key light and two fill lights. The Standard rig has a key light, a backlight, and a sidelight.
4-Point light rig It is a combination of the Standard and Studio rigs.
1-point lighting rig
Commonly a Spot Lamp is used for this rig
It producing an image with sharp contrast between light and dark areas.
An Example 1-point lighting rig
Key Light
2-point lighting rig
The combination of Key & Fill lights set high on either side of the camera give even lighting.
An Example 2-point lighting rig
Key Light Fill Light
3-point Studio Rig
The Studio rig consists of a key light and two fill lights.
The fill lights are typically placed on the side of the scene opposite the key light, illuminating the object from behind.
An Example 3-point Studio Rig

3-point Standard Rig
The Standard rig with a key light, a backlight, and a sidelight.
The key light, of course, is the brightest, positioned above, in front, and to the side of the object.
The backlight is less intense as compared to the key light and is positioned closer to the ground behind the object.
The fill light is off to the side, opposite the key light.
3-point Standard Rig
Key Light
Fill Light
Back Light
4-point lighting rig
This rig provides a good simulation of outside lighting—it's basically a hybrid of the Studio and Standard 3-Point lighting rigs. A key light illuminates the scene with the help of two fill lights off to each side. A backlight helps distinguish the background from the foreground.
