With the arrival of cell phones that all have cameras built-in, people everywhere began taking pictures more than any other time in history. As a result, many apps have been developed that help enhance photos as well. The quality of pictures that most people are able to take now is dramatically different than it was even five years ago. Compare the weight of a cell phone that one is likely to be carrying anyway, to the weight of the average DSLR, especially with all the extra lenses that likely accompany it, and it's easy to see why so many people have chosen to use their phones exclusively for photography instead of carrying around unneeded bulky equipment.
Of course, if you are on a really large investigation scene, your best bet will be the DSLR on a tripod. For a large area that you would like to catch as many of the details as possible of, a tripod mounted camera definitely has its advantages. I have also noticed that any time you have to use the zoom, that a DSLR with the right lens has a much better focus, depth-of-field, and resolution. Although the results are fantastic with a DSLR, they do require a higher level of knowledge about photography than your average point-and-click camera on the market. It also only used to be possible to take panoramic shots by using a tripod, however I have an app on my iPhone that does a better job than I have ever been able to do while taking my time, and using a tripod, so again, the phone is a great option.
New on the market is the GoPro series of cameras, which depending on your usage, comes with a variety of different waterproof cases and attachments to cover any inventive usage one might come up with. The quality is so good, that again, leaving the bigger DSLR at home seems wise. It also has a time-lapse function that can be very useful if you need see if something was affected over time. Because of its small size, light weight, and multitude of awesome attachments, the GoPro is worth serious consideration to add to your photo bag.
Again the question arises though; what do you do when in a situation where something, be it natural magnetic fields or effects of a craft of unknown origin, causes all your electronics to fail? Fortunately, Fuji Film still makes single-use disposable cameras, and you can order them on Amazon.com for a very reasonable price. Amazingly, there is still someplace to easily get your film processed. Walgreens still does all kinds of film developing, whether from a disposable single-use camera, or your vintage Minolta!
I hope this installment has given you some more ideas on ways to get that perfect picture and how to plan for any occurrence in the process!
