I spent the five happiest years of my life in a morgue. As a forensic scientist in the Cleveland coroner’s office I analyzed gunshot residue on hands and clothing, hairs, fibers, paint, glass, DNA, blood and many other forms of trace evidence, as well as crime scenes. Now I'm a certified latent print examiner and CSI for a police department in Florida. I also write a series of forensic suspense novels, turning the day job into fiction. My books have been translated into six languages.
I always loved mysteries and detection, but didn't want to be a cop.

Almost certainly, no. Unlike television, real forensic equipment is designed to test for certain things. For example the mass spectrometer in the toxicology department is set to test for illegal narcotics and not heavy metals such as arsenic. If arsenic is suspected, it could be detected with a different instrument or different parameters programmed into the same instrument. So I doubt there is any equipment that could be set up to detect microscopic amounts of photographic chemicals, if a photo would even shed any.

That's a pretty broad question. I can tell you that for both seminal stains and blood stains, the best way to package one is to let it dry, then place in a sterile paper envelope or bag. Never plastic! Then keep in a dry, cool environment.
Hope that helps.

I actually don't know. I haven't done DNA analysis in 20 years so I don't know all the details of what analysis can show. Sorry I can't be more help!
Share Answer: 
That entirely depends upon what agency you work for. Some police department crime labs may have that requirement. Many, like mine, have civilian employees for forensic support. The only way to know is to call the place you might want to work at and ask. (Or check their website for job postings.)
