Digital Camera Problems
Another problem with digital cameras is that they Rosetta Stone Language tend to need morelight than a film camera to create a comparable exposure. As a result,slower shutter speeds are often used to get enough light. This can makeit very difficult to take a photo without some blurring. The solutionis simple: use a tripod. They're not very expensive, and you can mountalmost all cameras to one. This step will result in a huge improvementin photo quality. If you have to take a photo with a slow shutter speedand you don't have your tripod handy, try using burst mode. It willtake practice to hold the camera steady (hold it against your face andexhale as you press the button), but the burst will give you a betterchance at getting one unblurred picture out of the bunch.
