Adjusting Image Colour

Adjust sliders to alter the graphics quality of an image that has been superimposed onto an object or scan. Hue, saturation, lightness and contrast are individually adjustable. Points not covered by the image are displayed in greyscale according to beam intensity.

1. Select an object which has an image (or multiple images) superimposed and registered onto it. Select the image name from the Image pulldown list, if not already selected.

2. On the Home ribbon tab navigate to the Colour group. From the Photographic drop-down list select Adjust Image Colour.

3. Adjust the image characteristics according to the options given below:
   

   • Hue changes the overall colour tint by moving through the colour spectrum.
   • Saturation affects the strength of colours.
   • Lightness adjusts the brightness of colours.
   • Contrast affects the separation between shadows and highlights.
   • Reset brings sliders back to central default positions.

4. Select Apply colouring to selection in order to transmit alterations to the object.

5. Select Hide points outside image extents so that only points coloured by the photograph image are visible.
   

Note:  A selection to hide points outside image extents on import is also available in the Preferences > Advanced settings.

6. Click OK to adjust the image and exit or click Apply to carry out the function without exiting.

7. Click Cancel to exit the function without any further actions.
