easy rendering for Rhino in Windows
|Understanding Flamingo nXt's Image Adjustment is key to understanding how to get good renderings from Flamingo.|
Flamingo nXt is always rendering in Luminance space. This means both color and actual light values are contained in a rendering. The values in luminance space contain a much broader range of values than can be displayed on a computer monitor. So we run the luninance values through a Tone Operator to compress the rendered image into colors that a computer monitor can display. You can control how the Tone Operator works in real-time giving you a lot of control over the rendered image.
There are 3 controls for the Tone Operator:
Brightness adjusts the overall Brightness of the image. So with Brightness, bright areas will get whiter, and dark areas will also get white. Colors and shadows all will get brighter. Use Brightness carefully, it is easy to wash out images.
Burn is a powerful control in the Tone Operator and perhaps the most important. Burn sets the white point of the image. This is the amount of light which will show white on the screen. Burn adds a bit of drama, life and sharpness to a rendering by adding more areas of white to contrast with the dark areas. Adding a little burn is always something to consider in an image.
Saturation controls the amount of color in the image. A saturation of 0.00 will result in a completely black and white image. By using values above 1.00 in saturation you can make colors richer and more extreme. This control is not used often, and if it is, then it is increased slightly.
By using the Brightness, Burn and Saturation controls you can quickly get an image that is dynamic.
