until a few years ago, there was no questionyou used a still camera
for stills and a video camera for motion. Now that boundary has
blurred. Many digital still cameras have a Movie mode, and many digital
video cameras include a still-photo button. So, when you want to travel
light, can one camera do the job of two? As with most things in life,
it depends. Compare that to a basic pocket-sized digital still camera today, which hosts a 3- to 5-megapixel sensor. With a 3-megapixel sensor, each image will have 30 times more information than a frame of video. But for still photography, you dont need to process 30 frames a second; 30 images in an afternoon is more likely. The purpose of a digital video camera and a digital still camera, then, is different in terms of image resolution, the number of images that can be captured and the speed at which theyre processed and stored. What about those cameras that claim to do both? Well, there are compromises. Its easier to design a camera to do one thing well. The more functions built into a device, the more compromises to be made by the engineers. Think about combining the fuel efficiency of a compact car with the cargo capacity of a pickupits difficult to have both.
