When I walk out the door I always have a camera with me, be it the camera in my iPhone or my DSLR, and as Chase Jarvis said "The best camera is the one that's with you".

Last week I found myself at a conference in Copenhagen and ended up living Chase Jarvis's saying, or something like that.

On the first day of the conference I only had my iPhone 4S on me and got a great shot of VP. Brian Thompson presenting "Creo 3.0" and you could say that the iPhone was the best camera at the time and for the job, being more discrete than a DSLR allowing me to capture the subject without disturbing it or my surroundings. (The sepia one is taken with my DSLR and the 50mm f/1.4 the second day.)

On the second day I brought my DSLR and got the shot of the Vestas turbine and Bella Sky, and for these shots the DSLR was necessary, allowing much more control of the shutter speed and the metering. In order to get the movement from the turbine blades in the shot of the Vestas turbine a very slow shutter speed of 1/25 second was needed, slow given the conditions and being handheld. The shot of the Bella Sky Hotel is really a composite of 9 shots, taken with the exposure locked to avoid a new metering for every one of the 9 shots, allowing for an easier merge of the photos in photoshop.

You could say that "The best camera is the one that's with you" is overall true, but the camera that's with you will also govern what you will and can photograph. So if there is a good probability that something photogenic will be in your path, bring your bulky DSLR along, unless you know that the stealth of a camera phone is really what the situation calls for like on a night out on the town.
