Figure 35-6 Digital color meter tool icon.
This tool is only available on a Mac OS, but there are other equivalent tools for Linux
or Windows. There are also open-source tools you can download for nothing. You might
be able to use the color-dropper tools in paint applications. Check out your copy of
Photoshop or Paint Shop Pro to see if the color dropper works when the cursor is outside
of the painting canvas. Then use it to measure the preview window in your compressor.
Adjusting for the Optimal Setting
Now that you have a way to measure the values, adjust the brightness and contrast to get
the optimum black and white settings for the frame being viewed.
