Ch. 8 - Viewing, Editing, and Annotating ImagesInsightB/WThe Convert to Gray Scale option is available only for RGB images that have been opened with theSPOT software/Insight Color camera. For monochrome image captures, the Convert to Gray Scaleoption is unavailable.From the Edit menu, select the Convert to Gray Scale option. The program converts the color image to agray scale image.Set Palette (monochrome images)The Set Palette option enables you to apply a specific color palette to acaptured monochrome image. There are four pre-defined color options:Grayscale, Red, Green, and Blue.To define a custom palette, use the Palettes option (Setup>Palettes).Refer to Ch. 4 – The Advanced Program Mode for more details. InsightB/W users can also apply palettes as part of the image capture process using the Palette option on theImage Setup window.Match ColorThe Match Color feature is typically used in two situations:• You want to change the colors of an image on the screen to match the way that you think the specimenlooks.• You want to set the white balance for pictures taken with a microscopic technique that never has whitein its images. A prime example of this situation is fluorescence microscopy.Note: The Match Color white balance adjustment can be used as an alternative to theCompute White Balance Values option.To use the Match Color feature, follow these steps:1. From the Edit menu, select Match Color.2. Click on OK. The cursor becomes an eye-dropper.3. Use the mouse to move the eye-dropper to the pixel location of the color that you want to match.Refer to the status bar at the bottom of the window to ensure that each of the R, G, and B values areless than full scale (255 for 24 bit RGB and 4,095 for 36 bit RGB).Note: If you select a pixel with a red, green and/or blue value that is saturated at full scale,the SPOT program prompts with a warning message indicating that you need to choose a pixelwith RGB values less than 255 (24 bit RGB) or 4,095 (36 bit RGB). Saturated pixels do notprovide a good reference point for correctly determining the RGB ratios needed for thisfunction.4. Click on the pixel. The Match Color window appears.Note: The Set White Balancebutton (not shown above)appears only for imagecaptures that have not yetbeen saved and closed.InsightB/WInsight B/W camerausers will not see theSet White Balancebutton.The window displays information about the pixel that you selected:User Guide to the SPOT Insight Camera 155
