Filters

Original Image rightOriginal Image A brick house downloaded from the 3D warehouse rendered in SketchUp.	Brightness Brightness The same model with Brightness increased by 5%
Contrast Contrast Contrast increased by 10%.	Saturation Saturation Saturation increased by 10%. Higher values add more color. Lower values move towards gray scale.
Sharpen Sharpen Filter Software sharpening creates enhanced sharpness by making the edges more contrasty. The algorithm notices when colors or intensities change in the image and sharpens up the transitions. You can apply this, and other filters repeatedly to enhance the effect. Just a little sharpening can add detail to a rendering.	Soften Soften Filter. Softening smooths out the transitions at "edges" - where the color or the intensity changes.
Smooth Smooth Filter. The Smooth Filter blends pixels together to create a smoother image. (Not just at color transitions.)	Gamma Gamma Filter Gamma filtering changes the intensities of colors to work better when displayed on a CRT screen. This image had a gamma factor of 1.2 applied.
Gaussian Gaussian 3 x 3 Filter A Gaussian Filter provides smoothing over a wider range (3 x 3 or 5 x 5) of pixels.	Embossed Emboss Filter The Emboss filter creates the effect that an image is embossed into a thin metal plate.
Edge Edge Filter. The Edge Filter recognizes edge transitions and displays only the edge lines.	Gray Scale Saturation set to 0. Setting the Saturation to 0 produces a gray scale image.
