Find a camera you can carry, then *use* it. Making the choice — now that’s the tricky part. For example, I was hauled into the back of a swat truck once in Uruguay because, unbeknownst to me, policemen were making a drug bust in the market I was photographing. I think they concluded I was working for some magazine or something because the camera I was using had one of those long telephoto lenses on the front. It was too high profile. My suggestion is – carry a camera that’s comfortable and practical for you, but beware of equipment that raises your profile unnecessarily. Right now, I’m using a Canon PowerShot G7. It’s one of those unique cameras that has essentially all the settings of a single-lense reflex, without the look of one; in fact, it carries reasonably well in my jacket or vest pocket, completely out of sight. But it’s probably too much camera if you’re not the type to study the owner’s manual. Again, the secret is to find something that works well. Read reviews online. When you notice that a friend or co-worker is producing great results, ask her what she uses, then see if that would work for you. And once you find something you like, stick with it — and *use* it. That means you’ll probably a little tripod to stick in your backpack or vest pocket. It’s the only way you’ll get shots with *you* in them (using the self-timer). My carry tripod is so light, I barely know it’s in one of my right vest pockets. It’s probably just 6″ long, but it’s generally all I need to capture a shot of a luncheon meeting or a time-exposure of a church building at night. I sacrifice a bit by carrying a rather powerful external flash. Those built-in on-board flashes are great if you’re only taking snapshots up to 11′ away. To capture all those new believers at 10pm, you’ll need something stronger. Get a flash attachment with a head that you can pivot upwards to “bounce” the flash off the ceiling so it illuminates the entire room. That’s the way to get a really pleasing picture at night without all the glare in your subject’s eyes.
