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.
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.

I'm not sure what you mean: a) how long after a print is left will ninhydrin still detect it, in which case I can say from my own experiment that there's little rhyme or reason to this, sometimes older prints develop better than newer ones or vice versa, or b) how long does a print developed with ninhydrin last, and the answer to that is that ninhydrin is a dark purple dye, so it is permanent, though it will continue to develop so that the entire page may eventually turn purple so we use a fixative chemical on the now-visible print so that will stop the ninhydrin from darkening the paper further. I hope that helps!

It may depend on what you want to do. If you want to work crime scene, then you might be a more attractive candidate with all the hands-on practical work of a forensic science degree. But if you want to be a DNA analyst, then I’d go with biology. Best thing to do is call the labs where you might someday apply and ask them. Best of luck!

Possibly, I suppose. If they were swabbed thoroughly and the swabs picked up a few skin cells, then it would be within the realm of possibility.

I used to analyze dried paint with an FTIR, which I believe would detect lead, but as to what would be better I really don’t know. Sorry I can’t be more help.

As far as I know, water doesn’t change the process of rigor mortis. The temperature of the water may speed it up or slow it down, but the process would still occur.

The requirements to work in a forensic capacity depend upon the agency--it might be anything from a high school diploma to a PhD for DNA analysis. The only way to know is to contact each agency and ask. Or at least check their websites, or the websites of forensic organizations such as IAI and AAFS, which post job vacancies. Drawbacks can be a lower salary than in the private sector, hours of work, having to work overtime or be on call. I don't know what you mean by 'self employ,' sorry. There are no 'freelance' type forensic positions that I know of, unless you have a specialty like soil analysis or anthropology, then you might be able to work doing consulting work when needed. But you'd have to have many years experience before that would be an option. I hope that helps! Best of luck!
