I want to buy a digital camera, but I'm afraid that by the time I learn how to use it, it will be replaced with a better model.
Welcome to the world of digital photography, where equipment obsolescence is a fact of life. Just remember, a good camera still takes good pictures, even after a newer, better model comes on the market.
I want to get into digital imaging, but I don't want to buy a digital camera just yet. Can I use my film camera to make digital images?
Yes, you can. You can purchase a film scanner or have your images commercially scanned. Scanner prices range from about $400 to $2000, and they can produce stunning digital images from 35mm negative or slide film. If you'd rather not spend that much money, many photofinishers can scan your images for you; they deliver your scanned images on a CD-ROM.
Should I buy a 3-megapixel camera now or wait for the next generation of 4 or 5-megapixel cameras?
This is always a tough question to answer, because no one knows where the mexapixel race will stop. Many industry experts think that 3 megapixels are more than enough for most non-commercial applications.
