Note: Some digital cameras can also
have close-up auxiliary lenses attached to the taking lens and so their
macro capabilities can also be enhanced. QUESTION: I have a good
35mm camera that takes excellent pictures. My husband wants to get a
digital camera to replace my camera. He says that digital cameras must be
better because they’re advertised so heavily and everyone is getting them.
Should I change and, if so, what features should I look for when I go
shopping? ANSWER: There are two questions here. I thought the first one was
the more important until I got to the last four words. The use of
digital electronics to make images or, in more simple terms, digital
photography, has done more to change the way people take pictures than any
other thing in the photographic field since film was invented. Indeed many
people look at picture taking in a whole new way. Once an image is
captured on film the piece of film storing that image is committed and can
no longer be used for anything else. So one has to continually use more
film to take new pictures. When pictures are taken with a digital
camera the images are captured from the sensitive sensor (which takes the
place of film) and stored as electronic files in the memory card in the
camera. Then the files with the pictures are copied to a computer or some
other more permanent electronic storage device without any loss of
quality. All the pictures on the memory card are then discarded and the
card is ready to be used again for picture storage. So once one has a
digital camera with a memory card and rechargeable batteries there is no
longer any film, processing, or batteries to buy. Because there is no
continuing materials charge tied to taking pictures with a digital camera
many people make far more pictures in any given situation than they ever
did with film cameras. Also, when a digital camera is used the picture can
be immediately examined to see if eyes are closed, or expressions are
unhappy, or if any other picture tragedy has occurred. So, with low
operating costs and immediate feedback why would anyone want to keep using
film cameras? The reasons to do so are many and we will discuss them in
the next column. Stay tuned. CHECK:
