The Image Editor is a Post Processing mode in IRender nXt to fine tune the appearance of the rendered image without having to change the model, lights, materials, or other settings.

nXtImage Mode

When you click the FX icon, and select the Image Effects tab, you will be asked if it is OK to Switch to nXt Image mode.

If you say Yes then the current rendering is saved in nXtImage format and reloaded. This can take several seconds - especially for a large image with multiple Lighting channels.

Note: If you start a new rendering, then the nXtImage changes will be lost and a new rendered image will be created.

Image Filters

The Image Filters convert the luminance data used by nXt into displayable or printable RGB pixels.

• Brightness - Brighten or darken the image.
• Contrast - Increase or decrease image contrast.
• Burn - See: Using Burn
• Saturation - Increase or decrease color saturation.

Vignette dims the outside of the image to highlight the interior.

Material Channels

Light Balancer

You can adjust the light channels in the Light Balancer to balance sun, sky and groups of lights. [[Image:Lighting Channels Tab.jpg]
