Methods

Three general types of post-processing methods are used to modify images:

  • Light and Color Adjustments: Modifying color, contrast, and lighting levels.
  • Effects: Adding atmospheric effects such as haze, blurred objects, and photo grain.
  • Entourage Modification: Placing realistic grass, enhancing water, and including backgrounds, skies, and objects. You’ll learn more about these methods in Chapter 32.
  • Combined Methods.

For best results, you can combine methods when it is appropriate. For example, haze, grain, and clay overlays will enhance the realism in exterior renders. Similarly, interior renders will benefit from adjusting the lighting levels, fixing hotspots, and altering color hue/saturation (Fig. 31.6).

Using Original Images and Layers

Before altering the image, make a copy of the original image by saving a copy of the file or duplicating the original image layer. A copied or duplicate layer of the graphic will allow you to compare or undo any modifications.
