Making a photo CD.. Help

[Micus]

Hi All and Merry Christmas,

I'm recently bought a scanner with a 35mm film negative adapter. I want
to scan a bunch of old negatives and place them on a CD for my parents.
However, I have no idea what resolution and format to store the photos. At
first, they will be viewed primarily on an 17"-19" monitor, but I would also
like to have them at a TV quality resolution. Any help will be greatly
appreciated...

Thanks In Advance,
M

It would help us help you if you tell us the scanner model so we know what
kind of optical resolution is possible.
Here is a general rule. For 35 mm film negative or slide, setting your
scanner resolution at 2400 to 2700 dpi will be fine. Above this you gain
very little and you get a very large file. You can drop this down to about
1500 and still get a very good display on your screen.
The major issue when you scan is, will you print.
The above, 2400 to 2700 dpi will yield a very good 8 x 10 print. At 1500, a
very good 5 x 7 print.
If you do not intend to print, you can use a lower resolution. Do some tests
at lower resolution than my above suggestions and see how the output file
looks like on your screen. If it looks good on your screen, it will look
good on your TV if you copy the file to a DVD disk and you play it on your
TV with a DVD player. However, don't expect a miracle on your TV. It has
less resolution than your PC screen.

Thanks Yves, this is just the type of info I was looking for. Sorry about
the late reply (Happy New Year). I have an Epson Perfection 3170 Photo
scanner (specs below). I was also wondering what format to save the photos
(jpeg, bmp, etc...).

Scanner type : Flatbed, color
Photoelectric device : Color CCD line sensor
Effective pixels : 27,200 x 37,440 pixels at 3200 dpi
Scanning resolution : 3200 dpi (main scan), 6400 dpi with Micro Step (sub
scan)
Output resolution : 50 dpi to 6400 dpi (50 to 6400 dpi in 1 dpi increments,
12800 dpi.
12800 dpi performed with zoom function)
Color separation : RGB color filters on CCD
Image data : 16 bits per pixel per color internal - 1, 8, 16 bits per pixel
per color external
Line Art settings : Fixed threshold
Gamma correction : 1 type for user-defined

Any other tips will be appreciated,
M

Always use JPG.
