What is TIFF ?
TIFF is an acronym for
Tag(ged) Image File Format. It is one of the most popular and
flexible of the current public domain raster file formats. etc. TIFF files are
relatively large when compared to JPEG.
Strengths: TIFF is primarily designed for
raster data
interchange. It's main strengths are a highly flexible and
platform-independent format which is supported by numerous image processing
applications. Since it was designed by developers of printers, scanners and
monitors, it has a very rich space of information elements for colorimetric
calibration, gamut tables, etc. Such information is also very useful for remote
sensing and multispectral applications.
Another feature of TIFF which is also useful is the ability to decompose an
image by tiles rather than scan lines. This permits much more
efficient access to very large imagery which has been compressed (since one does
not have to decompress an entire scan line).

What is JPEG ?
Short for
Joint Photographic Experts Group, and
pronounced jay-peg. JPEG is a
lossy
compression technique for color images. Although it can reduce files
sizes to about 5% of their normal size, some detail is lost in the compression.
JPEGs are better suited to displaying natural, complex images. Unlike a GIF a
JPEG is always full 24-bit color, so on anything but a 24-bit monitor it will
always be dithered by the browser.

How many pictures
per Data DVD?
The typical DVD has a capacity of 4.7 gig. Data DVD's are
formatted like CD's rather than Video DVD's. This would give you
approximately:*
| # of Images |
Resolution |
TIFF |
JPEG |
| 78 |

* These numbers are estimates only. If additional files (software,
etc.) are copied to the CD's/DVD's - the number of images per CD/DVD will
decrease. Actual file sizes will vary as well.

DVD Slide Shows
DVD Slide shows enable to your enjoy your photo album for viewing on your TV
set or PC. All you have to do is place the DVD in you computer or TV DVD
player and the slide show will start automatically. You do not have to
browse through each image from a file directory on your PC. This is
separate and addition to the individual slide/negative conversions you will
receive.
DVD Slides shows come in three styles:
- Simple slide show. One image shows and then replaced with the next
image
- Slide shows with transitions. Image fades out with various
transitions from image to image, making for more pleasing picture viewing.
- Slide show with transitions and music is the same as above, but in this
the slide show includes background music.
NOTE: Even though your
slides/negatives my be scanned at 2000 or 4000 ppi, the DVD slide show
will be in Industry Standard NTSC format. Since DVD's used are the
standard 4.7 gig DVD's they are not true HD quality found on a Blue Ray or HD
DVD giving you a 1080i resolution on your HD TV. Formats will be
either 4:3 or 16:9 based on your request.
