Compositing

Compositing by 3D-Ace

Scope of application of compositing is huge - from commercial reels and presentations of architectural projects to the movies. One of the hugest branches of compositing is combination of 2D images and 3D graphics, as it  is often the only possible way to achieve the desired result, when the elements that have come from different sources are combined together in a single seamless image.

To be more professional, compositing - is the process of adding special effects and adaptation of images using 3D graphics. As a result one get an image composed of several individual objects or layers, and special effects.

Professional compositing also includes color correction and rarely does without chroma-key – the exceptions are when the whole scene is modeled in 3D. As one can see, the success of a final image depends on many aspects.

Our experts apply two kinds of compositing:

  1. insert photo- and video materials in 3D environment,
  2. and, conversely, place 3D objects in the real world images.

Our artists often use these methods in architectural and interior visualizations, filling lifeless 3D scenes with real people and animals or, on the contrary, inserting a 3D building in a real city for a spectacular presentation.

It may become quite a difficult task to insert a real object into a 3D scene. 2D and 3D objects are often lit differently and our 3D artists adjust the brightness, contrast and color for a realistic effect. Highly skilled 2D artists / compositors can turn a sunny day into a cloudy one and can organically combine real-world and modeled elements.

To combine 3D graphics and real world images we use a variety of techniques, such as alignment of color palette, desaturation, halo effect, image graininess, channel blur, etc.

We take up the position that preparation stage is extremely important in 3D graphics and modeling in particular. Preparatory works that precede the compositing include the following stages.

  • First, we study the original image and its key elements such as light (number of light sources, their position and brightness), focusing length, shadows (their depth and sharpness), brightness, contrast, chroma and luminance level, etc.
  • Second, we edit the original image. For example, in architectural visualization it is required to keep the vertical lines in the image, so we correct the vertical lines if necessary.

The next stage is compositing itself. Our 3D artists can professionally combine 2D and 3D media content for the stunning outcome.
