Original Image

rightOriginal Image
A brick house downloaded from the 3D warehouse rendered in SketchUp.


The same model with Brightness increased by 5%


Contrast increased by 10%.


Saturation increased by 10%. Higher values add more color. Lower values move towards gray scale.


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 Filter.
Softening smooths out the transitions at "edges" - where the color or the intensity changes.


Smooth Filter.
The Smooth Filter blends pixels together to create a smoother image. (Not just at color transitions.)


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 3 x 3 Filter
A Gaussian Filter provides smoothing over a wider range (3 x 3 or 5 x 5) of pixels.


Emboss Filter
The Emboss filter creates the effect that an image is embossed into a thin metal plate.


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.
