About the blue spark -- I'm assuming that you don't have the blue because it's blown. Two things you can try:
1. Do you shoot RAW? This gives you more control over the exposure during post processing. You can open the file and adjust it the way you want it to appear for the mechanism itself, then open another copy of the same file, this time bringing down the exposure until you get the blue, and then merge the two images, masking out the appropriate areas.
2. If the RAW file still doesn't give you enough information, since it was advanced editing, you can take two pictures -- one exposure adjusted for the machine then one exposure adjusted to the blue spark. Then bring the images together masking out the appropriate parts.
That's what I would do -- there's probably other ways of doing it. :)
Feel free to PM if you have questions.
Again -- wonderfully done!!
