DIGITAL FILE FORMATS FOR PHOTO-VIDEO
MOVIES ON
DVD
Co
JPEG, TIFF, BMP, PNG for photos.
Which one to use?
JPEG (Joint Photographic Experts
Group) and TIFF (Tagged Image File Format) are two of the
most widely used image formats in the graphics industry.
The .jpg extension uses compression & can be compressed up
to 90%, of the original file size. This type of compression
is often called "lossy", because it results in a loss of
image data and therefore, image quality suffers.
TIFF (.tif) is a
"lossless" format
meaning no
compression hence
the quality stays
but the file size
increases. It
is not uncommon for
a .tif to be 5-7
megabytes (5-7MB)
and that means great
quality for graphics
etc. It is
used mainly by
professionals and is
not used on the
internet because of
the large file size.
Which
file type is the most
used?
On
the other hand, most people
that come to us do not
use the .tif format and
frankly, that is not a
problem. JPEG is
commonly used everywhere
and with our high
resolution scanners, the
quality does not suffer.
So if your photos are
JPEG, not to worry, your
pictures will look great
on DVD.
BMP &
PNG
The
.bmp file otherwise
known as a "bitmap" has
been around a long time.
There are several
versions of them but the
"Windows BMP" is the
most widely used of the
bunch. It is a
"lossless" type and it
holds it quality for
printing etc. As
you have deduced, it is
not widely used on the
web, but on some
instances it is.
The PNG format (Portable
Network Graphic) is one
of the more recent files
used on the web.
Other applications for .png
are video & television
graphics. Its
relatively small file
size & the ability to
have 8 - 24 bit RGB
image means its
appearance is widely
accepted on the net &
TV. So the .png
(called ping) is used on
our site & we use it
exclusively in our video
post work.
Whatever format you
have, rest assured AVV
PhotoVideo can use it!
