Digital Travel Photography Avoid Optical Zoom if Moving SUMMARY: Optical zoom may blur your digital photos taken from a moving vehicle.   If you are taking photographs from a moving bus, car, boat, or plane, consider avoiding, or lessening your use, of your digital camera's optical telephoto zoom. While telephoto zooms are quite useful in showing details of a remote location, they can cause some problems if you are shooting from a non-stationary vehicle. A telephoto zoom (or telephoto lens if you use a digital SLR) requires more light to enter the camera to take an effective photo. For more light to enter the camera, the shutter speed must be slower to allow the digital camera to absorb light. If the shutter speed is slow and you are moving, your photos may turn out blurry. Thus, consider using a wide-angle zoom (or lens if you are using a digital SLR) whenever possible. Note that on especially sunny days, you may not experience this problem, as your digital camera may be able to absorb enough light to take quick photos, so be sure to experiment.   Add: Del.icio.us | Digg | Furl | My Yahoo!   Discuss This Tip Print This Tip Get E-Mail When New Tips are Online Return to the Digital Travel Photography page.
