After you open your image, go to the menu item Analyze>Histogram.
This will show the number of pixels with the specified intensity
value. You can then adjust the displayed intensity by adjusting the
brightness and contrast from menu item
Image>Adjust>Brightness/Contrast. When moving the cursor over the
image, there is a display in the tool bar that shows the current
positions of the cursor and the pixel value.
Good luck,
Randy
