Proper Green Screen-Camera Lighting Techniques
With the changing world of technology, compositing, green screen lighting techniques are increasingly important with each passing year. When discussing lighting techniques chroma key, there are many things to consider in order to get the best performance, quality and configuration of the real image overlays to be completed in the departments of production and editing.
Not only green screens for longer
While speaking of screens on the greens all over the field, almost like an exclusive item, we neglect the traditional blue screens of the past. Lighting techniques is largely the same for both screens, and when the green screens were the primary basis for compositing technology that is the format we will talk more. While the green screens used in almost all of the video recording and production of today, there are some cases where the blue screens will be more suitable and ideal.
Everything begins and ends with the lighting
If your technique is backlight torque sub, then the entire production and the finished product will suffer. Lighting a chroma key set is not only perfect for capturing the essence of the plaintiff, but to avoid shadows, color combinations, unwanted and reflections that may not be visible during the recording, but it will rear its ugly head composite overlay.
There are those in industry who are in favor of the perfection of enlightenment, when you use chroma key techniques. Their design and layout of the various light has been carefully designed, tested, measured, and tested again before shooting begins. This can be ideal for big budget films, but it is not always necessary. The main idea of a good technique of lighting the green screen is to maintain a uniform distribution of light. sunlight outdoors under a white cover, such as tents, is a suitable light source that can be used. But there are many issues that may arise during a shoot when you use this technique, as clouds pass overhead or shadows that may be undetectable by shooting.
Using a chroma key background in a controlled environment is ideal. The set up is ideal for lighting a green screen or is it four or five light-hearted approach. Starting with a basic lighting plan with 3 points for your argument. This includes a key, fill, and backlighting.
1. Key Light – This is the main source of light, angles down toward the actor. Caution should be exercised to ensure that this light does not spill on bright green background.
2. Fill Light – This light is normally located in a corner opposite the actress led. Ideally, you want the light to be less intense than the key light will result in some light shade. This will help to create the illusion of 3 dimensions.
3. Light hair or back – Captures require a little ‘more light from above so that the actor’s hair or head is not lost in the overlapping composite assembly. This lamp will help separate the subject from the background.
4. Green Screen Light – Illuminates green screen itself. This device must be flooded to ensure a smooth, even cast of light. The fixture will be against a 45 degree angle.
5. 2: a light green screen – Set the same as the first from the opposite side of the set.
It is important to ensure that the light in the background is as smooth as possible.
Proper lighting chroma key does not stop with the light itself. When you shoot, you can be sure that the actor, or images that you use to shoot at least six to eight feet in front of the screen whenever possible. Otherwise it may cause shadows to be collected at the time of the overlap backgrounds added in post production. Also, make sure that there are strict as to hang clothes, hair or loose. These can cause problems when the background is added.
Proper lighting of the green screen is key to ensuring a positive chroma-key in post-production. Take time to define everything before you shoot, so when you get into the editing room, the background appears smooth on the actors.
