All of these Post Processing Functions are combined on the FX Wizard.

When first loading the Wizard your rendered image will be converted to nXtImage format so that the Haze and Depth Blur changes will be active.

Select the desired effects from the icon area on the left.

The Tone Filters, Material Channels and Lighting Channels are also directly available from the icon toolbar above your rendering.

Automatic Luminance or Photometrics automatically adjusts the overall intensity of your rendering, much like the automatic exposure on a camera.

If you want to adjust Lighting Channels or other items without having Photometrics apply, you can lock the Average Luminance on the Lighting Channels Wizard.

See: Automatic Luminance

Quickly Adjust lighting with the Brightness Slider .

The Brightness control is the most important Tone Operator control in IRender nXt. You cannot control the overall scene brightness by boosting the intensity all of the light sources. The automatic exposure adjustment built into the tone-mapping process will defeat this attempt.

You can adjust overall scene brightness by using the Brightness control.

See: Brightness Slider

Adjust the effect of sun, sky or groups of lights.

This is an excellent way to change a rendered scene from daylight scene to a nighttime scene without having to re-render it.

Adjust the color or luminance of a material after rendering.

With Material Channels you can select a face in the rendered image and adjust the color of all pixels rendered from the same material using the slider bars.

You can also use material channels to adjust the brightness of "glow" images - such as the screen on the monitor in this sample image.

Adjust Contrast, Burn and Color Saturation as well as Brightness.

• Brightness - The Brightness control is the most important.

Adjusts the overall brightness. For example, if a white surface in your model is rendering gray, you can increase the brightness until the surface appears white. Or, if your exterior scene seems overexposed, you can decrease the brightness until the scene appears more correct.

The default setting is 100 — smaller numbers produce darker images. For most renderings, small changes produce noticeable effects.

• Contrast - Adjust the contrast of the image.

Lowering the contrast makes the image more gray.

Raising the contrast make light area lighter and dark areas darker.

• Burn - Burn changes the white point of the image so that less than max brightness objects will map to white.

See: Using Burn

• Saturation - Controls the amount of color included in the rendering.

Slide it to the left to create a gray image.

Image Filters can sharpen or smooth your rendered image, or be used for other special effects such as creating an embossed effect.
See Image Filters

The Background Wizard makes it easy to position your rendered model in a background, and to remember the settings for future renderings.
See Background Wizard

Apply Real Time Haze or fog to your rendering as a post-process after the rendering is completed.
See Real Time Haze

Depth Blur settings effect how much the image is in or our of focus.
