A Pirate's Parrot

Every once in a while, I'm actually able to get a low light shot on a dark ride to a satisfactory sharpness.  This shot of the parrot at the front of Pirates of the Carribean is one example. 

It helps to have a fast telephoto zoom less.  Photography is all a function of how much light is being transferred onto the camera sensor (or film strip).  Either the shutter can be open longer to allow light to be captured for a longer period of time, or the aperture opens more widely (indicated by a smaller number in the denominator of the f/stop) for the same purpose.  However, unless both the camera and the subject are perfectly still, a longer exposure time can result in some sort of blur.  Thus, wide apertures become key to capturing low light images. 

Photographers will often refer to a lens with a wide aperture as being a "fast lens."  This is because the wider aperture will allow for a quicker shutter speed for the same exposure.  Understanding the inverse relationship between shutter speed and aperture is the key for a beginning photographer to make the transition away from simple "automatic" shooting and into more focused and intentional photography.  Then one can start to move on to how ISO factors into the equation, the effects that different apertures can provide on different photos, and issues like white balance and exposure bracketing.  I suppose I'll muse about those items in a future post...
