What should always be on your person when photographing?
Yea, compact flash cards but that's not the answer, neither is extra batteries which you should also carry. Maybe a flash light, yea but not the answer so what is it? A portable voice recorder should always be carried and they come in all sizes and quality starting with a few bucks up to several hundred. The purpose is to talk to yourself since photography is normally a lonely endeavor? No, but that could work, it is to take notes about things that need to recorded. For example, you think of something you should always bring, make a note of it. Or, you are remembering names, spellings, make a note of it. You are taking a photo and want to be reminded of something about the scene/creature, record it. Now, if you have a D3, Nikon realizes you should always carry a voice recorder so they built one into the camera, yea you can talk to the camera and it is embedded with the frame you are shooting. I make notes of places I want to come back to, record things about where to stay, even what to eat or bring for food. And recently, I have begun interviewing people I meet who are part of my photography. Kiteboarders for example, or surfers, they may have something I want to remember or better yet embed their interview in a slide show. When driving, I always keep a voice recorder handy to make notes of things I see and want to remember. It's easy, much better than trying to write it down, It is easy to download these files into itunes, label them and manage them in Garage Band. I figure when I get old with dementia, I can play back my life and enjoy photography all over again. See, I have an end game. Lately, I have upgraded my recording and added a boom mike to record animal sounds, surf sounds, traffic sounds, etc. I don't know exactly what I'm going to do with all this, but my intuition tells me I will figure it out. Warning, you do look a bit odd walking around recording ordinary sounds with a boom mike and a camera around your neck. I did have someone ask me if I wasn't suppose to be taking pictures(I assume they thought I was confused). Anyway, those of you with whom I have talked about being organized,know a voice recorder is an essential tool. And for those interested in upgrading, look at the Olympus LS-10, it is a jewel with studio quality in your palm. If you want an entry model, go to Office Depot and get one with a built in hard drive for under $20. If you want a project, think about creating a short slide show and recording the sound track from real life sounds that add to the images. Even wind blowing can create mood. Food for thought and enjoyment.
