How do digital cameras compare
with film cameras for underwater photography? Looking at the advantages
of digital cameras highlights the new possibilities in underwater
photography far beyond what was possible in the era of the film camera.
| Compact digital cameras are superior to film cameras in the
same class for shooting close-ups in macro mode. While film cameras
are subject to parallax on models with different sight lines
for the lens and optical viewfinder because the viewfinder field
is slightly offset from the actual area captured by the lens,
digital cameras eliminate this problem by allowing you to compose
with the LCD monitor, which uses the same sight line as the lens.
Digital cameras also have more depth of field, making it easier
to focus in macro mode. |
With a Digital Camera, you donÕt have to wait for film
to be developed. Since you can view your photos instantly wherever
you are, you can share them with friends at any point during
the dive or afterwards at the post-dive celebrations. You can
also view previously captured images underwater, making digital
cameras valuable communication tools for finding and identifying
fish. If you maintain a logbook of your diving discoveries, you
can use a card photo printer to print the images onto stickers
to add to your dive entries.

| Until the digital era, you couldn't see your photos
until the film was developed. Now, digital cameras show the images
the instant they are captured. Moreover, the right storage media
significantly increases your photo-taking capacity, allowing
you to shoot as many images as you like without worrying about
missed photo opportunities. Digital Photographic technologies
just keep on getting better. |
It was a laborious process to digitize an image in the era
of the film camera. First, you had to develop it, then you had
to scan it and finally retouch it. Now if you have a computer
and a digital camera, you can send it by e-mail or upload it
to a web page virtually instantaneously to share your beautiful
images with the world.
