This is probably one of the most dangerous things that you can do as a photographer. When the press gets shot at, and photographers get arrested for taking pictures of Ferguson, you know that you are entering a dangerous environment. While Photography is not a crime, there is a wide held belief in law enforcement that taking pictures of the police in action is illegal.
Plan on not resisting what ever the police tell you to do.
First things first, make sure your camera is connected to the Internet so that as you take pictures they are uploaded to a secure cloud service like Flickr, Smugmug, Zenfolio or other service that can take the storage of pictures as you go. I also highly recommend taking advantage of the Comcast XFinity public WIFI and carrying your own cell hot spot for your camera. You can expect jamming or at least the use of Stingray equipment so do not contact anyone on your phone just use it to upload your images to the net. Police will have a copy of everything you send when they use Stingray, and it might not transmit to the Internet depending on how Law Enforcement has the system set up.
You might want to transfer data laterally using Blue Tooth to a number of connected devices (more below).
In some ways it would be better to use an IPhone or something else that connects automatically to the internet, however you can set up your camera to use a WIFI enabled card on your camera like EyeFI and/or Transcender cards that way you have your local copy and one that is already on the internet. It is possible to jam the signals from your camera, which was seen in Hong Kong during the recent protests, but you can always use Blue Tooth to share the pictures laterally amongst a number of cell phones or connected devices.
If you transfer data laterally via Blue Tooth, carry a spare cell phone on you to store data, or travel with a friend that can also try to upload the pictures for you onto the Internet. The thing to remember is that you can have 7 devices connected, and that there is one master node with six slave nodes, however, the slave nodes can be masters in another mesh. This does work, but requires set up before you get to the event, and understand that you will want to have an in-depth mesh for this process to work. However it worked in Hong Kong to successfully get data out of the local Law Enforcement jamming of cell phones and networks.
Use twitter as a sending channel as well on the spot understanding that the signals can and probably are being intercepted. What you share with the Internet Law Enforcement will also be keeping an eye on.
If you are independent, hang out with a local news crew; some of the pictures I have taken have been from right behind a local news crew. We hung out, we talked, I told them I was an independent stringer, and I sold pictures to the local TV station while I was at it. This is one safeguard, as Law Enforcement will see you with a local news crew and make the assumption you are news and leave you alone along with the news crew. Don’t be an idiot about it, move around the crowd to get the pictures you want, but when it gets hairy, be close to a news crew.
Use professional equipment; using your IPhone to take pictures immediately says you are not a pro. Take professional DSLR gear with you; use your IPhone in your pocket to get the images onto the Internet. Your DSLR gear can take video as well as stills, you goal is to make sure you have access to the images and video you took off your devices in case you are arrested and have your gear confiscated.
Always cooperate with Law Enforcement requests, if they want you on the sidewalk get on the sidewalk.
Don’t argue, don’t complain, just do it.
A number of times Law Enforcement has after the protest asked me for copies of the pictures, that one is up to you. Your goal is to sell the pictures; you can sell them to Law Enforcement as much as you can sell them to the press. That one is up to your own ideas, but as long as they are in a public gallery Law Enforcement can also download them unless you have set up to sell the pictures first.
Cooperate with Law Enforcement, if they tell you to move on, move on. Find another vantage point to take the pictures from.
Stay out of the way, your goal is to document, not get arrested. Have a camera for close in, but if you are moved out of the way along with other media, find a roof top vantage point, and a super fast F1.8 200MM or 400MM lens to work with.
Try not to look like a sniper, police will have an issue with that, I highly recommend an orange reflective vest and a sign that says “PRESS” so that the police do not thing that you are a sniper.
At least you will get some good long distance shots. Shoot RAW to get as much data as possible, but if not shoot JPG Fine. The problem is going to be the upload and distance from the picture. Make sure you have plenty of remaining room on your cell phone or hot spot plan to cover the event. If you think you are going to shoot a full 32 Gig card, plan accordingly with your data plan so you don’t get over runs and the higher cost associated with that.
Be careful about flying drones around the area if you are using one. The FAA might have declared it a no flight zone. Make sure you are streaming the video to a storage system in case the drone gets shot down or gets interfered with or jammed. Use a cheap drone with a cheap camera because it will be likely that you will lose it. Fry’s electronics has a good collection of sub $100.00 dollar drones that have enough lift for a small video camera. You can hack a small video camera like the $20.00 Bang Good HD video camera and connect it to the drone and transmitter. You need to transmit it and connect it to power, but that won’t be hard to do either. Have a separate power source for the camera so you don’t interfere with the battery life of the drone you are using. In all you can cobble a good video drone for under $100.00 if you are of the type. You will need to be aware that they run on the same frequency as Cell Phones WIFI 2.4GHZ, and also subject to jamming. Some transmitters have multiple channels and work in the 5.4 GHZ range, so test your drone before you fly to make sure audio and video is coming through and not being jammed.
However, cheap disposable drones are an exciting advance in photography for covering important events. That cannot be understated, it keeps the photographer safe and somewhat untraceable, while capturing amazing photography and video of an event.
While the goal here is not to antagonize Law Enforcement, being an independent stringer for covering riots and other actions carries its own risks. If you are detained expect your devices to be gone through, and in some cases the video will be copied or erased from your devices. It is easy to recover the data using commercial off the shelf forensics tools, but you might need help with using them, or pay for the data recovery.
Be prepared, be realistic, and above all be safe when doing this. There is something sweet about close in photography, but the inherent danger might require that you move out of the way and go remote.
